Thanks for the tips. I checked the connections in the circuit breaker panel and the electrical safety box/switch and they are all nice and tight. The fuse that is blowing is the replaceable one in the electrical safety box/switch, not the circuit breaker in the electrical panel. After replacing several fuses it's safe to say there is an overload issue vs a fuse issue.
If it is the type that allows the fuses to snap in, not screw in, then the connection is not tight and is overheating, blowing the fuse. The more times you change it the looser it will get. Like someone said above, use an inexpensive clamp meter to verify the current and either bypass the fuses or replace the fuse holder portion inside the safety switch.
