Operation of a Coleman Manual Transfer Switch?

Question

I have a Coleman Manual transfer switch wired to my main panel for my generator but no manual. It was already installed when I bought the house. When I use the generator during power outages do I need to turn off the main breaker in my panel? What is the proper way to use the transfer switch?

Answer 1

Wired correctly, you can use your generator to power devices in the transfer panel while the regular AC powers the rest of the house, all at the same time. I do this sometimes as a load test for my generator. There is no need to turn off the main breaker in the panel. If you are expecting an extended outage you may want to turn it off anyhow, just to protect your house against any power surges or spikes which often accompany a return of power.

The Coleman transfer switch is very similar to the Generac 1276 switch. I have a pdf manual online...

Note that this style of transfer switch does not switch neutral, so your generator should be wired with a floating neutral, not bonded to the chassis.

Read my generator page for other safety items for home backup generators.

Answer 2

Providing the transfer switch is wired correctly, all you need to do is start your generator and place the transfer switch handle in the generator position.

I recommend hiring an electrician to check for proper wiring. You may also want to check Coleman's website to see if you can obtain a manual for your transfer switch.
