Trane -- House inspection -- Maximum Breaker Size

Yes it should be fixed. 35 amps is a standard breaker size, but you'll probably have to go to an electric supply house to get one. I'm impressed that a home inspector caught it. This post crossposted back to AHR so as not to offend boy Pauly.

Hey a GREAT HOME INSPECTOR! Good catch too bad more arent that good:(

Definetely replace that breaker!

I am not sure where you shop, but in 30 plus years I have never seen a 35 amp RESIDENTIAL breaker. I do so little residential that it is possible. A quick google for square dog proved no such animal.

A fused disconnect at the unit with 35 amp time delay fuses would solve the problem. Sadly most contractors use the damn pullouts now days instead of a fused disconnect. If indeed the infector is right. Have you actually looked on the unit yourself? All a/c units say min and max circuit capacity.

What does the local jurisdiction have to say? You said new house, or is it just new to you?

If there is a problem with the compressor it will indeed trip a 40 amp breaker.

Try this;

Actually, if the unit calls for a Maximum Fuse OR breaker size of 35 amps, a 35 amp fused disconnect at the outdoor unot will do fine. If the unit nameplate says maximum breaker size (without mentioning a fuse size), then you must use a 35 amp breaker.

I carry the 15 and 25 and the 35 amp Square D, GE, and Homeline breakers on my truck for just that purpose. These are residential plug in breakers, 2 pole. Not the screw in commercial types. The big box stores don't always have them, but I get them easily at electrical supply houses.
