What size wire?

Fishfried · Mar 5, 2020

Two questions:

1. What gauge wire to run between batteries for a 24 volt trolling motor? The wire that runs between + and - terminals.

2. My fuse panel is a foot from the battery. What gauge + and - wires should I use to go to the fuse panel? The panel is for bilge, aerator, livewell pump (all 500gph) LED nav lights and some small LEDs for night fishing.

Thanks

1) Not less than 8 gauge

2) Not less than 10 gauge

You should not suffer any voltage drop, or low voltage problems as the electrical load increases in either circuit with my recommendations.

It all has to do with how much length you will be running, the volts and the amps you are pushing. There is a wizard on the Blue Sea website: https://www.bluesea.com/

Regardless of what the recommended size is, I always prefer to go at least one size larger for safety.
