I’m purchasing a new build with some issues with the wiring of the HVAC system.
The home has a AC unit that says it is rated to a minimum current draw of 36A.
So my home inspector informed me that the 8AWG wire leading from the AC Unit to the 60A breaker was improperly set up, since 8AWG wire is not rated for currents that high.
However, a 3rd party inspector hired by the home builder to counter-act that stated that it would be okay, since due to code, the Maximum breaker allowed would be 60A, and that the maximum current that the conductor has to carry is 45A, so that an 8AWG wire is okay.
When presented with this, my own inspector stated that you’re still not allowed to mix a 60A breaker with 8AWG wire which will fail at currents lower than 60A, and I’m inclined to side with him.
Does having an AC unit of 36A draw on a 8AWG wire and 60A breaker meet code? Or do I need to require them to replace the 8AWG wire with 6AWG as suggested by my inspector?
