120v switch over

I have installed a wine cooler (120v) I want to wire it to my inverter (stand alone) and to shore/generator and be able to switch over from inverter to shore/generator power to inverter (back-n-forth) based on hook ups or boon-docking. Need schematics.

There are two ways

Auto-Transfer hook the mains feed (The feed from the breaker panel) to the GENERATOR input and the inverter to the SHORE input

Manual Transfer..DPDT switch NOT from Radio Shack but from a proper electrical supply... A transfer switch can not be switched from Main to Inverter without a stopp off at OFF or at least passing THROUGH off.

NOTE: I have no problem with an SPDT switch but I do not think it is code.. Better to switch both black and white wires.

Home is where I park it!

Why not always run from inverter? When on shore power your battery charger is charging batteries...

If you really want to switch, you could use a regular three way switch for homes. The same type used to switch on a light from two locations.

You would tie the black from the wine cooler to the "common" on the switch, the black from shore to any other two and the black from invert to the remaining. Tie all whites together et voila.

You can buy a auto transfer switch from West Marine.

It plugs into the inverter, so 1/3 of the wiring is done for you.

You just cut the feed to the cooler outlet and wire it in. You could cut the cord and put it inline there.
