It'll be a long time until I'm putting in electrical panels, but I need to have my wiring planned out so that I can do the rough wiring in the ceiling soon.
My battery and main distribution will be in a tongue box, and originally I planned to run all 12v circuits from there, through the ceiling, and out to the various switches and fixtures in the trailer.
Today it occurred to me that it would shorten all the wire runs, and decrease the number of wires going from tongue box to camper if I had a separate distribution panel in the camper.
So, does it make sense for me to have basically a main and sub panel arrangement for my 12v distribution? There would be an ATC fuse block in the tongue box, serving a couple nearby circuits. One of those circuits would be a 20A circuit with 10ga wire going into the cabin to supply another fuse block inside the camper. Branch circuits would come off that cabin fuse block (fused down to 5a mostly) and using 16ga wire to feed lights, receptacles, etc.
So, any thoughts on the two options?
Plan A: Run every circuit from the fuse block in the tongue box
Plan B: Supply a second fuse block in the cabin from the tongue box main block, and run most cabin circuits from the second in-cabin fuse block.
Thanks for your input!
