Some of the older Casitas have a DC fridge
circuit run with 12 ga wire and sharing the fridge
with the entry light
and porch light
. Better to have the fridge
on its own circuit and upgrade to 10 ga wire to minimize voltage drop and resistance.
This is how it was done on a 2000 Casita
Starting at the fridge, remove the two wires on the left side of the terminal block. Remember, where black and white were connected,

feed the new wires thru from under the bench and attach.
run the wires along the existing wire bundle, using tywraps to secure, to the back of the trailer and across to the converter side
Bring the wires in thru the back of the converter (I folded back about a foot of wire and tywrapped it just in case the slack was needed sometime in the future). Cut to fit. The white (ground) wire goes on the large terminal in the lower right of the photo. Black wire goes on a terminal below the empty fuse terminals. Plug in a 15amp fuse (for the small fridge), turn the fridge on DC and if the chimney gets hot, it'll work. Don't leave it on DC very long without a charger hooked up to the battery
This photo is after my wiring was installed. Notice the second fuse from the left, a fat black wire, that's my fridge circuit. The fat white wire is hiding behind the others on the ground terminal.
