I am converting to a Spal electric fan and have a wiring question. I ordered the wiring kit from the vendor and what I received was a kit that has both a 30A breaker and a 40A fuse. The instructions show wiring the kit using the breaker as circuit protection and don't address the fuse whatsoever. I feel the fuse was included in the kit for a reason but cannot find a diagram which uses both a breaker and fuse for circuit protection. I have found systems that utilize a 5A breaker for protection between the switched ignition source and the relay, but nothing that depicts a circuit breaker and fuse in the same system. Can anyone shed some light on the reason my kit has both a fuse and breaker? Has anyone else used both in a fan electrical circuit? Should I just use the breaker and discard the fuse? Should I use the fuse and discard the breaker? Does this paragraph sound like the end of an episode of "Soap"? Just trying to get my ride squared away. The vendor is no help. They sell the parts they get from their distributor.
