Ok... I can’t stand it any longer.
The breaker you install has nothing whatsoever to do with the equipment your going to use on that circuit. The breaker is chosen for the size of the wire you run in the walls. PERIOD!!!
The amp is protected by the fuses in the amp! Not the circuit breaker.
The only thing protected by the breaker is the wire use in that circuit. If you have a 50amp 240 v circuit, FINE! The amp will use what it needs. The fuses will protect it from overdraw of current.
The circuit breaker will protect the wire to the receptacle. PERIOD!
If you don’t know this you should hire an electrician. PERIOD!
Talk about a thread that’s gone on too long!
