Can Fuses Be Used In Place of Circuit Breakers When Installing 4 to 7-Way Adapters
Question:
I am piecing the parts together to for the 4 pin adapter. I am buying the 12 gauge wire but can I use an in-line fuse instead of circuit breaker? If circuit breaker is needed, what size? If in-line fuse, what size?

Expert Reply:
In regards to a 4 to 7-way adapter, you'd need to use a fuse or circuit breaker on both the brake output circuit as well as the battery charge line circuit. I recommend the Universal Installation Kit for Trailer Brake Controller part # ETBC7 since it comes with everything you need. The battery charge line with need to have 40 amp protection and the brake output circuit will need to be 20 or 30 amp depending on the number of braking assemblies. We use circuit breakers since most are auto resetting which means you don't have to replace the fuse if there were a short.
