I have seen several different answers and got different answer from each of the licensed electricians I know. Here is the situation.
Pool sub panel is a 90 amp Cutler Hammer breaker wired with 4 AWG aluminum wiring. The type of wire is THHN2. Now from what I could get from it is that this wire is MAX rated for 75 amps of power. I know the higher temperature rated wiring can facilitate more power. But doesn’t the connection point also have to be properly rated.
So is this wire good enough for a 90 amp sub panel fed from the main panel and were can this be found specifically.
Thanks in advance.
