[Amps] I need transfer switch information

Good point.  I could tie the main and generator neutrals together and just switch the hots.

I have a Portable, pull-start, Honda generator and fortunately we have only lost power for less than 2 hours in the 9 years we have been living at our current home.

Thanks to you, now I only need a DPDT, which is probably easier to find.

Many thanks,

Ken W2DTC

    I would like to switch out two circuits from my main panel to an emergency generator with a manual transfer switch or a contactor.  I've sketched out a circuit that will do this even when the main panel is live and I will need a 3PDT switch.

  You only switch hots so you only need a DPDT switch.  Should not switch neutrals
