How to Wire an RV 50 Amp Outlet

If you own an RV, it’s important to have the appropriate electrical setup to power your vehicle and all its appliances. One crucial aspect of this setup is wiring a 50 amp outlet, which provides the necessary power for larger RVs. Here’s a step-by-step guide on how to wire an RV 50 amp outlet.

Step 1: Gather the necessary materials. You’ll need a 50 amp RV outlet, a double-pole 50 amp circuit breaker, a 14-50R receptacle, a weatherproof box and cover, electrical wire, wire connectors, and electrical tape.

Step 2: Turn off the main power supply. Before starting any electrical work, make sure to turn off the main power supply to avoid any accidents.

Step 3: Select the location. Choose a suitable location for the 50 amp outlet, preferably close to where you park your RV and with easy access to the main electrical panel.

Step 4: Install the weatherproof box. Mount the weatherproof box on a sturdy surface and secure it properly. Make sure it’s grounded by connecting a green grounding wire to the grounding screw on the box.

Step 5: Run the electrical wire. Measure the distance between the weatherproof box and the main electrical panel. Cut the electrical wire to the required length and run it through the conduit from the panel to the box.

Step 6: Connect the wires. Strip the insulation off the ends of the wires and connect them to the corresponding terminals of the 50 amp RV outlet, following the manufacturer’s instructions. Typically, the black wire goes to the brass terminal, the white wire to the silver terminal, and the green wire to the green terminal.

Step 7: Install the double-pole circuit breaker. Turn off the main power supply once again and install the double-pole circuit breaker in the main electrical panel. Connect the black wire to one of the circuit breaker terminals and the white wire to the other terminal. Make sure the green grounding wire is connected to the grounding bar.

Step 8: Test the outlet. Turn on the main power supply and test the outlet using a voltage tester to ensure it’s functioning properly. If everything is working as expected, you can now safely connect your RV to the 50 amp outlet.
