Re: Refrigerator off main breaker?
We use a dedicated fuse for the fridge, wired directly to the battery. Fuses cause less voltage drop than circuit breakers. Our fridge is always on.
Actually, our compressor is well aft, far from the house bank and right near the shore power charger. I use the (now disconnected) shore power charger's wire. It's 6 gauge. Then I have the fridge fuse coming off that, to a short-ish 14 or 16 gauge wire. 5 amps load. Seafrost says to make sure the compressor gets good power.
