It is an important safety measure that protects your RV’s electrical system from any voltage spikes or surges that may occur during power outages or when you’re traveling.
In this article, we’ll guide you through the process of installing and wiring a 30 amp RV transfer switch. We’ll cover the tools you’ll need, the steps you’ll need to take, and provide you with a wiring diagram to help you along the way.
Tools You’ll Need
Before we get started, let’s take a look at the tools you’ll need to install and wire your 30 amp RV transfer switch. You will need:
- Wire strippers and cutters
- Screwdrivers
- Drill
- Power drill bits
- Wire nuts
- Electrical tape
Steps to Install and Wire a 30 Amp RV Transfer Switch
Step 1: Turn Off the Power Supply
Before you start working on your RV’s electrical system, it is essential to turn off the power supply. This will prevent any accidents or injuries from occurring. Locate the main breaker or disconnect switch in your RV and turn it off.
Step 2: Choose a Location for the Transfer Switch
The next step is to choose a location for your transfer switch. The transfer switch should be installed in a location that is easily accessible and close to your RV’s electrical panel. It should also be mounted securely to a wall or other solid surface.
Step 3: Mount the Transfer Switch
Once you have chosen a location for your transfer switch, it’s time to mount it. Use your power drill and drill bits to drill holes in the wall or surface where you want to mount the switch. Then use screws and a screwdriver to attach the switch to the wall or surface.
Step 4: Connect the Wires
Now it’s time to connect the wires. First, connect the two hot wires from the generator to the transfer switch. Then connect the two hot wires from the RV’s electrical panel to the transfer switch. Next, connect the neutral wire from the generator to the RV’s electrical panel. Finally, connect the ground wire from the generator and the RV’s electrical panel to the transfer switch.
Make sure all wires are connected properly and securely. Use wire nuts to connect the wires together, and use electrical tape to cover the nut.
Step 5: Test the Transfer Switch
Once you have connected all the wires, it’s time to test the transfer switch. Turn on the power supply and test the switch by turning on the generator. Then, turn off the generator and test the switch by turning on the RV’s electrical panel. If everything is working correctly, you’re good to go.
