Well
Electrical fire at AC terminals on circuit board was probably due to loose/corroded connections.
Water environment requires higher degree of maintenance.
Wow, ok, so the fuse would not blow? There is a 5 amp fuse on the powerboard, and a circuit breaker at the main ac panel.
So, are you saying there was resistance at the powerboard AC connector, causing it to heat eventually igniting the wire insulation or other?
I guess I thought a fuse would blow, but I guess not in the above scenario as the current never exceeded the fuse rating.
Scary, as this would apply to a residential fridge or any appliance on board.
So how do you maintain this, after the applicance has been powered on for a while feel the wire for warmth? Learned something new today, thanks guys...
5A fuse on circuit board is for the AC circuit/electric heater element. Not for the AC power coming to board. That is what the AC circuit breaker for the OUTLET power cord plugs into is for.......15A CB
Need to check the tightness and keep terminals on circuit board clean.
As suggested..di-electric grease---water environment.
Also go thru your Main AC Panel and check/tighten ALL terminal lugs.
Best of luck!
