PVC conduit is a popular choice for underground electrical installations due to its durability, resistance to corrosion, and affordability. However, selecting the right schedule rating for PVC conduit is crucial for ensuring a safe and reliable electrical installation. In this post, we’ll explain the different schedule ratings for PVC conduit and provide tips for choosing the best schedule for your underground electrical project.
Understanding PVC Conduit Schedule Ratings
Schedule rating is a term used to describe the wall thickness and pressure capacity of PVC conduit. The higher the schedule rating, the thicker the wall and the higher the pressure capacity of the conduit. The most common schedule ratings for PVC conduit used in underground electrical installations are Schedule 40, Schedule 80 PVC conduit, and Schedule 80 electrical conduit.
Schedule 40 PVC Conduit
Schedule 40 PVC conduit is the most common and affordable type of PVC conduit. It has a wall thickness of 0.154 inches and can withstand pressures of up to 120 psi. Schedule 40 PVC conduit is suitable for most residential and light commercial underground electrical installations.
Schedule 80 PVC Conduit
Schedule 80 PVC conduit is thicker and stronger than Schedule 40 PVC conduit, with a wall thickness of 0.218 inches and a pressure capacity of up to 200 psi. It is ideal for underground electrical installations that require extra durability, such as those in areas with heavy foot or vehicular traffic.
Differences between Schedule 40 and Schedule 80 PVC Conduit
The main difference between Schedule 40 and Schedule 80 PVC conduit is their thickness and pressure capacity. Schedule 80 PVC conduit is more durable and can withstand higher pressures than Schedule 40 PVC conduit, making it suitable for more demanding underground electrical installations. However, it is also more expensive than Schedule 40 PVC conduit.
Factors to Consider When Choosing a Schedule for PVC Conduit for Underground Electrical
Several factors should be considered when choosing a schedule for PVC conduit for underground electrical installations
Depth of burial: The deeper the conduit is buried, the higher the pressure it will be subjected to. If the conduit is buried deeper than 18 inches, Schedule 80 PVC conduit is recommended.
Soil type: The type of soil can affect the pressure that the conduit will be subjected to. If the soil is rocky or has a high water table, Schedule 80 PVC conduit is recommended.
Electrical load: The amount of electrical load that the conduit will carry can affect the pressure it will be subjected to. For installations with high electrical loads, Schedule 80 PVC conduit is recommended.
Environmental conditions: The environment in which the conduit will be installed can affect its durability. If the installation is in an area with heavy foot or vehicular traffic, or in an area with exposure to harsh weather conditions, Schedule 80 PVC conduit is recommended.
Local regulations and codes: Local regulations and codes may specify the type of PVC conduit that is required for underground electrical installations.
Best Practices for Installing PVC Conduit for Underground Electrical
Proper installation techniques are crucial for ensuring a safe and reliable underground electrical installation. Here are some best practices for installing PVC conduit for underground electrical:
Proper trenching and bedding: The trench in which the conduit will be installed should be at least 18 inches deep and wide enough to allow for proper bedding. The bedding material should be a minimum of 4 inches deep and should be compacted.
Correct installation techniques: The conduit should be installed in accordance with local regulations and codes, which may require specific burial depths, minimum bend radii, and proper use of fittings and couplings.
Use of appropriate fittings and couplings: The use of appropriate fittings and couplings is crucial for ensuring a watertight and secure connection between sections of PVC conduit. All fittings and couplings should be made of PVC material and should be rated for use with the specific schedule of PVC conduit being used.
Conclusion
Choosing the right schedule rating for PVC conduit is crucial for ensuring a safe and reliable underground electrical installation. Schedule 40 PVC conduit is suitable for most residential and light commercial installations, while Schedule 80 PVC conduit is recommended for more demanding installations that require extra durability. Schedule 80 electrical conduit is suitable for installations that require extra heat resistance. When selecting a schedule for PVC conduit, several factors should be considered, including the depth of burial, soil type, electrical load, environmental conditions, and local regulations and codes. By following best practices for installing PVC conduits, such as proper trenching and bedding, correct installation techniques, and the use of appropriate fittings and couplings, you can ensure a safe and reliable underground electrical installation.
Among the many types of conduit materials available, two stand out as the most commonly used: PVC conduit and steel conduit.
One of the first questions you might ask is: “Should I use PVC conduit or steel conduit?”
It’s a common dilemma because both materials offer distinct advantages and disadvantages depending on the application.
In this post, we’ll provide a clear and detailed comparison between these two popular conduit types.
We’ll cover everything from their material characteristics and the key industry standards they comply with, to practical considerations like installation ease, costs, and upkeep.
Additionally, we’ll examine how PVC and steel conduits hold up in different environmental conditions, helping you make the best choice for your project.
Whether you’re an electrical contractor, engineer, project manager, or anyone involved in electrical work, this guide maybe helpful for understanding the differences between PVC conduit and steel conduit.
Let’s get started!
To begin, we’ll focus on the materials being used and how they perform in terms of strength, flexibility, and other mechanical properties.
2. PVC Conduit and Steel Conduit: Material and Physical Properties
PVC and steel conduits are made from very different materials, and those differences shape how each performs in the field—from installation and safety to how they age over time.
Interestingly, despite their material contrast, both PVC and steel conduits come in two main types:
Rigid conduit, used for fixed, straight runs where protection and stability are essential;
Flexible conduit, used in areas that require bending around corners, movement, or vibration absorption.
Let’s take a closer look at how these materials behave in real-world conditions.
PVC electrical conduit, or polyvinyl chloride conduit pipe, is a type of thermoplastic known for being lightweight, corrosion-resistant, and electrically non-conductive.
In terms of physical performance, PVC conduit pipe typically offers a tensile strength around 5,000–8,000 psi, and is heat-rated up to 90°C (194°F) or much higher for continuous use.
These values can vary by manufacturer and specific product formulation, so it’s always a good idea to consult the supplier or product datasheet for exact specifications when making a purchase.
However, it may become brittle in cold weather and soften when exposed to high heat.
Steel conduit is much stronger and more impact-resistant. Made from galvanized or stainless steel.
Steel conduit offers tensile strength between 30,000 and 60,000 psi, excellent durability in high-traffic areas, and far better heat tolerance than PVC—often functioning in environments exceeding 400–500°C, depending on the application and protective coatings.
However, it’s heavier, conductive, and may corrode if not properly protected.
UL, IEC, AS/ NZS and CSA provide specific testing and classification methods, they all aim to ensure conduits meet core performance needs—mechanical strength, insulation, fire safety, and long-term reliability.

3. Installation and Handling of PVC Conduit and Steel Conduit
When it comes to installation, the differences between PVC and steel conduit become immediately obvious—especially to anyone who’s actually had to run several hundred feet of it on-site.
PVC conduit is often favored on job sites for one simple reason: it’s easy to work with. It’s light enough for one person to carry several sticks at once, and can be cut with a simple handsaw or even a fine-toothed blade. There’s no need for threading equipment or heavy-duty tools—just a clean cut and a deburring tool to smooth the edge.
Joining conduits and installing fittings for corner turns is also simple.
Most rigid PVC conduits use a solvent welding process: apply primer and cement, push the fittings together, and you’re done. It chemically bonds in a few minutes and sets quickly.
For flexible PVC, connectors usually snap or screw into place with a compression or locking ring—no heat, no glue.
Some types of PVC conduit can be bend with a heat gun or bending heater. With the right technique, it’s possible to make smooth bends around corners without special fittings.
In short: PVC is lightweight, requires minimal tooling, and installs fast.
Steel conduit installation is a different experience entirely. It’s heavier, tougher—and more demanding, both in terms of tools and physical labor.
There are usually three types of steel conduit: RMC, IMC, and EMT.
EMT is thinner and lighter, so in some classifications, it’s not considered a “true” rigid conduit.
Compared to PVC conduit, installing steel conduit like RMC or IMC is more labor-intensive. It typically requires cutting with a pipe cutter or hacksaw, threading the ends with manual or powered tools, and using thread sealant, bushings, or locknuts for secure connections.
If the metal-to-metal connection isn’t solid, a bonding jumper (a wire) is added to keep the system electrically continuous.
Bending steel conduit takes more effort—mechanical or hydraulic benders are often needed, and larger sizes may require powered equipment.
EMT, though lighter, still demands skill and force to bend with a hand bender.
Steel conduits do offer unmatched strength and protection, but from a labor standpoint, they take more time, more tools, and more training to install correctly.
4. Cost Analysis of PVC Conduit and Steel Electrical Conduit
When budgeting for an electrical conduit installation, material cost is one of the most visible expenses.
There are several other factors that can influence the total cost of a conduit system, including transportation, labor, installation accessories, and long-term maintenance.
💵 Material Price (Reference Only)
We searched a range of commercial sources to get a sense of typical market prices for both PVC and steel conduits.

💡 Note: Actual prices can vary depending on supplier, product quality, manufacturing process, and even region. They may fluctuate due to material costs, inventory levels, or supplier pricing models. Always confirm with the supplier at the time of purchase.
🚛 Transportation Costs
PVC conduits are significantly lighter in weight, which means lower shipping costs, especially for large-volume orders or remote site deliveries.
Steel conduits, being heavier and bulkier, typically cost more to transport and may require special handling.
🛠 Labor and Handling
Labor is another major cost driver. PVC conduits are easier to cut, join, and bend using basic hand tools. This speeds up installation and reduces labor hours—especially helpful on large-scale or fast-track projects.
Steel conduit is harder to work with compared to other types. It needs to be threaded, bent, and properly grounded. It may need specialized tools and more skilled workers to install it, so it typically takes longer to complete the job.
⏱ One case study showed that installing PVC can be up to 30–40% faster than steel in indoor commercial applications.
🔩 Accessories and Tools
Each conduit system comes with its own set of fittings and accessories. The cost of these accessories—both in money and time—should be factored into your total budget.
🧰 Long-Term Maintenance and Repair
PVC is resistant to rust and chemical corrosion, which reduces the need for protective coatings or replacements. However, it may degrade under UV exposure or extreme heat over time.
Therefore, we recommend using solar conduit for outdoor applications under direct sunlight.
And in the other hand, steel conduit pipe offers long-term strength, but may require anti-corrosion treatment, especially in humid or coastal environments, adding to upkeep costs.
5. Conclusion
Choosing between PVC and steel conduit depends on many factors — from material properties and installation ease to cost, environmental conditions, and safety requirements.
There’s no one-size-fits-all answer to which conduit is better. By looking at all the factors—material, cost, installation, and environment—the best choice is always the one that fits your specific project needs.
PVC offers lightweight, corrosion-resistant, and cost-effective solutions ideal for many applications, while steel provides superior strength and fire resistance where mechanical protection is critical.

Think of PVC conduit as the protective tunnel for your electrical cables — just like how a well-built subway keeps trains safe and running smoothly underground.
If the tunnel is built poorly, trains might slow down or get stuck.
Similarly, if PVC conduit is installed incorrectly, it can lead to problems like damaged wires, safety risks, and costly repairs.
If you’re planning to install PVC conduit for your electrical wiring project, this post may be helpful.
Some common mistakes include poor planning, choosing the wrong conduit size, overfilling the conduit, too many bends, using the wrong fittings, ignoring environmental factors, poor sealing, especially outdoors or underground, improper cutting, failing to secure the conduit, neglecting electrical codes, and not planning for future expansion.
In this post, we’ll walk through the most frequent slip-ups people encounter when installing PVC conduit.
Whether you’re a seasoned electrician, a DIY enthusiast, or someone just starting to learn about electrical installations, understanding the common mistakes people make with PVC conduit can save you a lot of time and money.
2. Poor Planning Before Installation
Here’s a truth that many people learn the hard way: jumping into PVC conduit installation without a clear plan is like setting off on a road trip without a map or GPS — you might get somewhere, but it probably won’t be the right place, and you’ll waste a lot of time and energy along the way.
Poor planning can lead to all kinds of headaches: wasted materials, having to redo work, unexpected obstacles on site, or even safety hazards.
For example, without a proper layout plan, you might end up with conduits running in awkward directions, too many bends, or unnecessary lengths that increase both cost and complexity.
So what does good planning look like? Start by sketching a simple conduit route on paper or with digital tools. Think about where your cables need to go, any obstacles you’ll have to work around, and how to minimize bends (each bend makes pulling cable harder). Also, consider future expansion — it’s smart to plan for any additional wiring you might add later.
Many of the mistakes we’re about to introduce stem primarily from a lack of proper planning. One common example is choosing the wrong conduit size — a seemingly small decision that can cause big problems later on.
3. Choosing the Wrong Conduit Size
Picking the right size of PVC conduit might seem straightforward, but it’s one of the easiest mistakes to make.
Imagine trying to squeeze a big group of people through a narrow hallway. It’s going to be uncomfortable, slow, and maybe even unsafe, right?
The same goes for your electrical cables inside the conduit.
If your conduit is too small, the cables get cramped, making it harder to pull them through, and they can overheat because there’s less space for heat to escape.
On the other hand, if you go too big, you’ll end up wasting materials and space — kind of like buying a jumbo suitcase when a carry-on would do.
So, how do you get it right? The National Electrical Code (NEC) usually recommends filling no more than 40% of the conduit’s internal area to keep things safe and manageable.
Before buying or cutting any pipes, take some time to calculate the total diameter of your cables and choose a conduit size that fits comfortably. A little planning here will save you from pulling your hair out later!
We talked earlier about the importance of choosing the right conduit size — and now, let’s take that one step further. Even if you’ve selected the correct diameter, overfilling the conduit is still a common pitfall that can lead to serious problems if not handled properly.
Imagine trying to shove too many clothes into a suitcase — it bulges, the zipper strains, and you just know something’s going to rip. PVC conduit works the same way. When it’s overfilled with too many wires or cables, you put your entire system at risk.
Overfilling is one of the most common — and most overlooked — mistakes in electrical conduit installations. It may not seem like a big deal at first, but cramming too many conductors inside a conduit can lead to:
Overheating
Increased friction during pulling
Difficulty in future maintenance or upgrades
Non-compliance with electrical codes like the NEC
The National Electrical Code (NEC) has strict rules about conduit fill capacity.
For example, if you’re using three or more conductors, the total cross-sectional area of all cables must not exceed 40% of the internal area of the conduit as we have mentioned above.
Sounds a little technical? Don’t worry — there are charts and tools to help.
📘 If you are interested in diving deeper into how to calculate PVC conduit fill properly, here we provide a post Understanding PVC Conduit Fill Charts: A Comprehensive Guide (2025) that explains everything in detail for you — checking out if you want to get the numbers just right!
5. Avoiding Excessive Bends
When planning your PVC conduit installation, one of the most important things to pay attention to is how you handle bends and turns.
Think of your conduit like a smooth highway for your cables. If the highway has too many sharp turns or twists, traffic will slow down, and accidents are more likely.
Similarly, too many bends in your conduit make it much harder to pull cables through, and could even damage them.
According to electrical standards like the NEC (National Electrical Code), the number of bends between pull points should not exceed 360 degrees total. This usually means you can have up to four 90-degree bends or their equivalent.
If your conduit path requires more than this, you must install a pull box or junction box at strategic points. These boxes give you access to change direction safely and make cable pulling manageable — like rest stops on that winding highway.
Also, the NEC advises using long-radius bends instead of sharp 90-degree angles whenever possible. Long-radius bends give cables more room to curve gently, reducing strain and making installation smoother.
6. Using Incorrect Fittings or Accessories
Using the wrong fitting is a bit like wearing the wrong size of shoes — it might get you through the day, but it’s going to be uncomfortable, and eventually, something’s going to break.
The same goes for PVC conduit installations. Fittings are the key to connecting and securing your system, and choosing the wrong type or size can lead to loose connections, water leaks, or even code violations.
Wrong size match: Just because two parts seem to “fit” doesn’t mean they’re the same size. Using a fitting that’s too tight or too loose can compromise the entire system. Always match the fitting size to the conduit diameter exactly.
Mismatched types: Electrical PVC conduit fittings are different from plumbing fittings, even if they look similar. Using a plumbing elbow or coupling in an electrical application is a common but critical mistake — electrical fittings are designed for wire pulling and code compliance.
Improper transition fittings: When connecting PVC conduit to metal boxes or other materials, it’s important to use the correct male adapters, threaded connectors, or transition couplings to maintain grounding and mechanical integrity.
Skipping box connectors or locknuts: When entering a junction box or enclosure, you should always use box connectors and secure them properly with locknuts. Otherwise, the conduit might shift or disconnect over time.
When installing PVC conduit, one common mistake is overlooking the environment where the conduit will live.
🌳Think of it like planting a tree—you wouldn’t plant a delicate tropical tree in the middle of a snowy tundra and expect it to thrive, right? The same idea applies here.
Environmental factors such as temperature extremes, UV exposure, moisture, soil type, and even chemical exposure can all affect how well your PVC conduit performs and lasts.
🌞 UV Exposure: Prolonged sunlight can degrade some types of PVC conduit, making it brittle over time. If your installation is outdoors, choose UV-resistant conduit or consider painting it with a UV-protective coating.
❄️ Temperature Extremes: PVC can become brittle in very cold weather or soften in extreme heat. Make sure to select conduit rated for the temperature range of your location.
💧 Moisture and Soil Conditions: Underground conduit faces moisture, soil acidity, and shifting soil. Proper sealing, burial depth, and choosing conduits designed for direct burial are crucial.
⚗️ Chemical Exposure: Some industrial sites or agricultural settings have chemicals in soil or water that can degrade PVC. Always verify that your conduit material is resistant to any chemicals it might encounter.
Ignoring these factors might lead to premature cracking, leaks, or system failures. So, take the time to assess the environment and choose the right materials and installation methods — your conduit will thank you later!
8. Poor Sealing for Outdoor or Underground Use
Installing PVC conduit pipe outdoors or underground? Then sealing isn’t just a good idea — it’s essential. Think of it like building a tent in the rain 🌧️.
If you don’t close up every flap and seam, water will find a way in. And just like that soggy sleeping bag, your conduit and wiring could suffer.
Many people overlook this step or assume the conduit will naturally be waterproof once it’s connected.
Unfortunately, that’s not the case.
Water, dirt, insects, and even plant roots can sneak into unsealed joints or entry points, leading to corrosion of conductors, short circuits, or degraded insulation over time.
So what should you do?
✅ Use approved solvent cement to seal joints completely, proper solvent cementing is one key part of sealing, but it’s just one piece of the puzzle.
✅ Apply watertight fittings like gaskets, bushings, and weatherproof connectors, especially where the conduit enters an enclosure or box.
✅ Seal entry points into buildings or underground boxes with weatherproof sealant or expandable foam.
✅ Use expansion fittings if temperature changes are expected, especially in outdoor runs — this prevents gaps from forming when conduit expands or contracts.
📌 Pro tip: For underground installations, always follow NEC and local code requirements for burial depth and backfilling — and double-check that your conduit ends are completely sealed before covering them up!
9. Improper Cutting and Deburring
Cutting PVC electrical conduit might seem like a simple task — just slice and go, right? But improper cutting and deburring can cause more trouble than you’d expect.
Imagine trying to push a delicate cable through a conduit with rough, jagged edges inside — it’s like trying to slide a smooth ribbon through a rough keyhole. Those sharp edges can snag, damage, or even wear down the cable insulation over time, leading to shorts or failures down the road.
So, how to do it right?
✅ Use a proper PVC conduit cutter or a fine-toothed hacksaw for clean, straight cuts.
✅ After cutting, always deburr the inside and outside edges using a reaming tool, a round file, or sandpaper — smooth edges help cables glide through easily.
✅ Take your time and check each cut before installation to avoid surprises later.
Before we dive into the specific challenges of underground PVC conduit installation, let’s quickly recall a few important points we’ve already touched on — like the critical role of proper sealing to keep moisture and dirt out, the use of expansion fittings to accommodate temperature changes and prevent gaps, and the strategic placement of pull boxes to make cable pulling easier and avoid excessive bends.
These elements lay a solid foundation for a durable and trouble-free underground conduit system. However, underground installations come with their own unique challenges and potential pitfalls that we should be aware of.
✅ Incorrect Burial Depth
One of the most common mistakes is not following the required burial depth. According to the NEC (National Electrical Code), the minimum burial depth for rigid nonmetallic conduit (PVC) in most residential applications is 18 inches.
However, this can vary depending on factors like voltage, location (driveway, lawn, or under a building).
✅ Skipping Conduit Markers or Warning Tape
Underground conduits are easy to forget once buried — until someone accidentally digs them up! This tape acts as a bright, early alert for anyone digging in the future.
Lay a continuous warning tape about 12 inches above the conduit to avoid accidental damage later.
✅ Improper Backfilling
Improper backfill can crush or crack PVC conduit, especially under pressure from vehicles or heavy soil.
Use soft fill material like sand or clean soil around and over the conduit first. Compact it in layers to avoid shifting, then finish with your usual fill.
11. Failing to Secure Conduit
Imagine trying to build a house without nails or screws — no matter how well you line things up, they won’t stay in place for long.
The same logic applies to PVC conduit: if it’s not properly secured, your entire electrical system could suffer.
Improperly secured conduit can sag, shift, disconnect at the joints, or place stress on fittings and enclosures.
Over time, this not only looks messy but can also lead to cable damage, compromised seals, or violations of building codes.
To avoid this, always follow spacing guidelines set by the National Electrical Code (NEC).
For example, smaller-diameter PVC conduit may require support every 3 feet, while larger sizes may allow wider spacing — but only if the material remains stable and straight.
And finally, choose support materials that are appropriate for the environment. In outdoor or corrosive settings, consider UV-resistant or corrosion-resistant clips and anchors.
12. Neglecting Electrical Codes and Regulations
Throughout this guide, we’ve mentioned how important it is to follow the NEC — the National Electrical Code — and there’s a good reason for that.
If you skip over code requirements or assume they don’t apply, you’re taking a big risk. Mistakes like the wrong burial depth, incorrect conduit size, or poor sealing could all lead to fire hazards, shock risks, or expensive do-overs — and you may even fail inspection.
Every country, and sometimes even different cities or regions, may have their own electrical rules. It’s important to check what’s required in your area before starting any installation. Whether it’s NEC in the U.S., AS/NZS standards in Australia and New Zealand, or local codes elsewhere, all of them exist for one goal: safety and reliability.
So before you pick up your tools, double-check the codes. Following the rules from the start is always easier (and cheaper) than fixing a mistake later.
13. Not Planning for Future Expansion
Earlier, we talked about the importance of choosing the right conduit size and planning your layout before installation. One key reason for that is often overlooked: future expansion.
Electrical systems rarely stay the same forever. Whether it’s adding new equipment, outlets, or lighting, chances are you’ll need to run more cables down the road. If your conduits are already full, you might face major headaches — like tearing everything out just to add a few wires.
What’s the smart move?
✅ Choose a conduit size that allows room for future cable runs — not just what you need today.
✅ Leave access points or junction boxes where new circuits could easily tie in.
✅ Document your layout clearly so future upgrades won’t be a guessing game.
A little foresight now can save a lot of time, money, and hassle later. Think of it as building not just for today — but for tomorrow too.
14. Conclusion
Installing PVC conduit might seem simple, but as we’ve seen, even small mistakes can lead to big problems later — from water damage and overheating to failed inspections or expensive rework.
The good news is, most of these issues can be avoided with good planning, attention to detail, and by following safety standards like the NEC.

Connecting PVC conduit to an electrical box typically involves the use of a PVC conduit connector or a PVC conduit hub.
Here are the general steps to follow:
Step 1: Measure and Cut the Conduit
📏 Use a tape measure to determine the required length of PVC conduit for your setup.
✂️ Then, cut the conduit using a PVC pipe cutter or a fine-toothed saw. Ensure your cut is straight and clean.
Step 2: Deburr and Smooth the Edges
🧹 After cutting, remove any burrs or rough edges on both the inner and outer ends of the conduit using a deburring tool or utility knife. This step helps prevent damage to wires during installation and ensures a smooth connection.
Step 3: Prepare the Electrical Box
🛠️ Ensure the knockout on the electrical box is removed and clean. Knockouts are the round, perforated sections on electrical boxes designed for fitting connectors or conduit.
Step 4: Insert the PVC Male Adapter
🔩 Insert the threaded end into the knockout hole on the side of the electrical box. Hand-tighten until snug and flush against the box. Use pliers if needed, but don’t over-tighten to avoid cracking the plastic.
Step 5: Apply PVC Cement (Flexible conduit can pass)
🧴 Apply a thin, even layer inside the socket end of the male adapter, and another layer on the outside end of the PVC conduit. Work quickly — PVC cement sets fast.
Step 6: Connect the Conduit to the Adapter
🔗 Push it in firmly until it bottoms out inside the fitting. Hold it in place for 15–30 seconds to let the bond begin setting.
Step 7: Let the Joint Cure
⏱️ Most PVC cement requires at least 15 minutes before handling and up to 2 hours for a full cure — always follow the manufacturer’s instructions.
Step 8: Pull the Electrical Wires
⚡ Once the connection is solid and dry, you’re ready to pull the electrical wires.
