So I'm planning to run power to the back of the cargo area so I can run some accessories. These include a 12 volt fridge/freezer, Smitybilt air compressor, a 600W inverter, and a 12 volt fan.
Also in the mix is adding a 200 amp battery isolator, and an existing 200 amp alternator. One question I have is if all the 2 guage is overkill for the battery and starter connections?
The inverter is 1200W peak, which should be drawing around 100Amp(?). According to the wire gauge charts 4 gauge should be OK for that.
The fridge I'm looking at says it only draws 5.4 amps
The Aircompressor is either 30 or 45 amp max, so should that have it's own power too?
So I'm planning on running 4 gauge wires back to the inverter, the air compressor, and a 6 place fuse block. Below is a sketch of what I'm thinking.
Any advice would be appreciated.
