I am adding a Renogy 60 amp DC to DC charger to my 2021 ford transit RV build. It draws 90 amps input so would attaching it to #14 175a auxiliary power point 1 on the pre-fuse box under the driver seat with a 100amp breaker be safe and not interfere with anything
ReplyDeleteI’m trying to find the trailer fuse,
