I'm new in this. I remember there was a formula to determine what the amp size of the conductors or wires need to be based on the amp specs of the load. Does anyone know what it is?
I think load has to be 80% of the breaker size. Is that right?
Say a plate on an electrical device says 30 amps. This is the only device that is going to be used on this circuit. The breaker has to be 125% or 1.25 times the 30 amps. But wire running between device and the breaker has to able to handle a load greater than 30 amps. Is there a formula or multiplier to determine how many amps of wire to use?
