How to Wire an Onan Transfer Switch
Wiring an Onan transfer switch may seem daunting, but it’s actually a simple process. Here’s a step-by-step guide on how to wire your Onan transfer switch:
Step 1: Turn Off Power
Before you begin wiring your transfer switch, make sure to turn off the power to your home’s electrical system. This will ensure your safety and prevent any electrical accidents.
Step 2: Mount the Transfer Switch
Mount the transfer switch near your breaker box, ensuring it is securely fastened to the wall. Make sure to install any necessary conduit or wiring between the transfer switch and your home’s electrical system.
Step 3: Connect the Power Wires
Connect the power wires to the transfer switch. The power wires will consist of three wires: the black wire, white wire, and green wire. The black wire is the hot wire, the white wire is the neutral wire, and the green wire is the ground wire.
You’ll need to connect the black wire to the transfer switch’s hot input, the white wire to the neutral input, and the green wire to the ground input. Make sure to follow the manufacturer’s instructions for connecting the wires, as the wiring configuration may vary depending on the type of transfer switch you have.

You’ll need to connect the black wire to the transfer switch’s hot output, the white wire to the neutral output, and the green wire to the ground output. Again, make sure to follow the manufacturer’s instructions for connecting the wires.
Step 5: Test the System
Once you’ve wired your transfer switch, test the system to make sure it’s working properly. Start your generator and turn off the main power to your home. Your transfer switch should automatically switch your home’s power source to your generator.
