When inspecting service panels, I compare the wire sizes to the breaker sizes. #14 AWG (Cu) - Max 15 amp breaker, #12 AWG (Cu) - Max 20 amp, and so on. Many times I will catch a #14 AWG (Cu) attached to a 20 amp breaker and call that out as a potential safey hazard.
Here’s the question, What is correct call when there is a #14 AWG (Cu)attached to a 20 AMP 220V breaker for an A/C unit? The namplate of the A/C is attached.
Minimum Circuit amps 12.6 (#14 AWG Cu is OK)
Running Load Amps 9.0 x 125% = 11.25 (#14 AWG CU is OK)
Maximum breaker size 20 amps OK
14 AWG Cu on a 20 amp breaker. Circuit breaker too large for wire capacity. Recommend evaluation by a licensed electrician
I evidently ticked off the electrician when he was called back to this property because of this. Without being technically exhaustive (knowing what circuits feed what in the home) How should this be reported?
I will be talking with the local AHG on Monday morning. I’ve also have seen #12 AWG on a 25 amp and 30 amp breakers in the past.
