I'm planning to add a dedicated inverter for my 120VAC refrigerator. Would like to build a transfer switch that would switch the refrigerator between the 2 inverters and shore power / generator. The one inverter has a transfer switch to accomplish the shore power / generator switching.
A transfer switch is essentially one or two relays. In some transfer switches, a relay is used for each power source to prevent contact arcing. I'm looking at a maximum of 4 amps AC, and trying to determine whether I need 2 relays, 1 relay with two double pole double throw contacts, or if I can find it a 4 pole double throw relay.
Thoughts?
