The ARC panel fuses the trigger for the relay. The main feed to the relay that powers the pump should have a circuit breaker or fuse properly sized for the wire and the load it's feeding. If the fuse is rated higher than the wire the wire burns. That's the reason I posted the wire gauge chart, size and length of the wire is important.
I have a friend with an ARC panel and it was the same deal but he didn't have a relay and still burned the wire, basically his wire became the fusible link.
