Extending power cable

[Juan]

I'm hardwiring a trolling motor and getting the wires off the deck but to do it right, I need to extend the wires about 3 feet. I'm guessing currently the wires on the trolling motor going to the receptacle are 12 gauge (stranded) and the wires from the battery to the receptacle are 6 gauge (stranded). Can I splice about 3 feet of 12 gauge (solid) wire without any voltage loss?
I'm thinking if 12 gauge solid copper wire can handle 120 volts AC, it should handle 12 volts DC?

The volts aren't the concern, it's the amps you need to consider. Current will flow easier through a larger gauge wire than a smaller gauge.

Got it. Thanks. I used a jumper cable wire (#4 stranded) and connected that to the original #8 so should be good.
