Gauge of Wire for Using as Charge Wire for Trailer Battery


My trailer connector needs a wire from the battery to connect and charge the trailer battery. Its a Scamp trailer. What wire gauge should I use? 10 AWG? What fuse should I use? Thanks.


Expert Reply:

For charging a trailer battery you want to go with as thick of wire as you can. 10 gauge would be ideal. We sell 10 gauge wire by the foot with part # 10-1-1.

Typically a 40 amp breaker like part # 9510 is used.
