Can someone please answer this one correctly. I am so tired of reading comments or arguments in regards to wire size and breakers on a compressor unit.
Same old story.
50 amp breaker on 30 amp wire.
Max breaker 50 amp
Min circuit ampacity 23 amps.
To me this means you can get away with 30 amps to run, or 50 amp max or the circuit may not trip before damage to the unit occurs.
Last compressor I had go bad, turned my breaker into charcoal. It would have also fried my wiring if it had been undersized due to load from the weak compressor.
I also find plenty of burnt wires in disconnects or panels, from what I suspect is due to oversize breakers.
Unless someone can show me how this is possible, I will continue to write up small wire and big breaker.
Charlie do you have an answer?
