What ever the reason, you now have two lines connected where one was before and an overheating
problem that is likley to get worse. Would suggest you get or make new cables (2/0 wire should be more than enough to handle your current
load) and a new switch and fuse holder before you end up with a fire which can ruin anyone's day.
I'd also suggest a label or sign with big letters near your AC switch reminding to turn on the generator
. I have a numberf of those 'disaster avoidance labels on my boat.
Even better I split my AC wiring
, and no inverter.
The no inverter, (A/C's stove, water
heater, etc...), come directly from AC buss fuse bank, the buss is split with the only connection being a circuit breaker that feeds inverter, inverter output is then connected to the other side of the buss. With the inverter loads (outlets, fridge, lights), on that portion of the fuse bank.
Inverter has a bypass that essentially takes it out of the circuit and leaves all AC devices powered by shore power
. In case of power failure the loads on the first part of the buss simply lose power, and the inverter keeps the second buss powered.
No need to run around in a panic switching off high power devices in case someone trips over shore power
cord, or worse blowing inverter leaving you with NO power.
Inverter is sized to power full load on second buss, so no worries.
I try to "idiot" proof my boat as much as possible, as the idiot may be me at three am, while fumbling in the dark to turn something on.
