A condenser unit is newly installed and the manufacturer minimum rating on the equipment is 32.6 amps.
Inspector finds this unit installed on a 30A circuit. Is it a code complying installation?
If not what is the fix?
Pretty common here in Nor Cal

The undersized 30 amp breaker could prematurely open. You would hope that the wire SIZE was installed to handle what the max rated amps the unit calls for and go with the next size higher 40 amp breaker. Remember that an undersized wire and an oversized breaker could result in a FIRE and equipment damage. I would say it is not to code its not to mfg. specs calls for.
I really don't to be a pain but...
The open areas are not where this should be. Questions like this should be in the Professional areas.
Yeah, I know this is fun for us but it could be considered to be DIY help and you could loose your posting privileges.

Why are you asking? Doesnt make sense. Anyone smart enough should know that any piece of equipment that pulls x amount of amps should not be on a circuit rated for less than that. You say that you see that alot? I have never seen that anywhere I have ever lived. You ask what is the fix? The correct way would be to run larger wire with the proper sized breaker, although I'm sure there are many morons out there that would just put in a larger breaker! Unless there is something I am missing, I dont see how an inspector would pass something like that. Someone correct me if I am wrong.:confused:
