How to Connect PVC Conduit to Electrical Box

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.
