I picked up a Truckfridge tb51a recently and I'm continuing my build(I'll update a journal when I get a chance).
I'll be running the fridge off a set of 6V golf cart batts maintained by an Iota dls45/iq4 converter-charger. Though capable of running off 120V, the fridge will be run(wired) only by 12V as TF suggests switching back to 120V, when a good supply of 12V is available, is somewhat unneeded duplication(and a waste of power) as the fridge converts 120V to 12V to run anyway.
The camper has a 50A 120V service and distribution panel that runs only the AC/heater and Iota charger. There are no other 120V loads. (30A would have been plenty, but the 50A service was installed already..so..50A it is..).
All the 12V power draws will be switched and run off an individual circuit-fused 12V distribution panel. All the 12V circuits are run through a switch panel in the galley. All switches have a 20A rating. Each switch has a small red led to indicate "on".
My question:
Are there any issues with wiring the fridge circuit with a switch? The fridge comes with a 16 gauge 12V power cord. I'll cut off the round 12V cigarette-lighter plug and hardwiring the fridge to the 12V panel. The fridge comes with its own fuses installed. The fridge circuit will be WELL within a 3% voltage drop distance with the 16ga wire. The fridge can be shut off with its own control panel, but I'm thinking it might be better to have the lighted switch installed in the main panel to make it easier to see the on/off state of all power draws in one place.
