Rotary Switch replacement
I am new to this forum and finally made the jump to a trawler after many years of dreaming about it. I have just bought a boat with, I believe, a bad transfer switch for incoming power. Presently both AC circuits will work on shore power at both AC circuit panels but not when set to generator. The generator is putting out 118 volts at the generator and there is 117.9 incoming at the transfer switch #1 (house panel switch). The air conditioning panel is only energized by shore power at this time. I would like to have two new switches in the lines so that the 2000Watt inverter, the 8 K generator, or a 30 Amp shore power cord can power the house panel and a 30 Amp shore cord or the 8K generator could power the Air Conditioning panel. Since the 8k Genny should be about 66 amps I will have to install a bus bar to split it into two 30 Amp lines through circuit breakers and then feed these lines into the rotary switch. I am not sure if the Inverter has to go through the transfer switch as it will automatically switch to inverter when AC power is interrupted and back to AC when it is restored, but I have had an automatic switch start a fire in my last boat so I thought it prudent. If it could be wired directly into the panel that could change the switch configuration – I am looking for simplicity but also for safe operation.
