My wife and I live aboard and most of the time we manage our shore power loads with infrequent circuit breaker trips. Our Taiwanese trawler has the standard 2-30A 125V shore power cables. One cable provides 30 amps to the air conditioning and one provides 30 amps to the rest of the boat electrical systems. We have a ship shore switch and a 8KW generator wired for 125V.
I am contemplating another air conditioner and would like to have more amperage for the rest of the boat.
Going to 50 amp 250Volt is not practical and I would have to rewire the generator and change too many devices and upgrade too much wire.
But I am considering two 50 amp 125volt shore cables from a 50 amp 125/250 Y. I would change the inlet fittings and up the wire size to the ship shore switch. I would change my 2 main breakers from 30 amp to 50 amps and up size the connecting wires from the ship shore switch.
My estimate for new Y adapter, cables, inlets, wire and breakers is about $1200. For this I would have 100 amps on board instead of 60 and I might have to manage load when on generator.
Any comments? Sanity check please?
