Proper gauge of wire?

[65 overlander]

The 2 way Black and White wire that, goes from Trailer Umbilical to rear of trailer to Batts. The black insulation is brittle and a new splice wont work, being that the brittleness goes back to far. I replaced the tongue umbilical, Breaker, and common sense says ,Fix all! Any info would be great! Thankyou in advance! Jeff

Use #10 gauge stranded copper THHN or THW or THWN you can find at Home Depot or Lowes......
Run new wiring all the way back.... don't splice
If you run the wiring under the belly pan and exposed, go to an r.v. supply house for special two conductor jacketed cable...

Good luck!

since it is your charge line you may want to keep your voltage drop ro a minumum.

this chart may help in your choice of wire.

Thanks John, I'm in the middle of rewiring the 18-footer (Boris) and needed a chart like this. LP

if you read carefully on that chart you can use 5% voltage drop for lighting.

it will save you a couple of bucks on wire.

duh

on edit, just use the 2% table, the other one is for 120 volt.

If you're really really good at it, and real lucky, you CAN tie the new wire to the old, and pull it through without taking anything else apart.

I was thinking of using a wire mesh gripper, to hold the new cable and use the old as a guide. But are there any cable clamps holding the cable from moving around, if so , I dont want to take on removing the belly, but I also understand that running it on the outside would look sloppy! Thank you again for the quick responses. Jeff
