My son is buying a townhome and had it inspected. The inspection
report said that the A/C was overfused. This sounds like a simple fix
to me - that of replacing the breaker with a lower rated breaker.
Or am I missing something important here?
The inspector was just reporting that the breaker was too large for the wire
He wasn't making any judgement about the ampacity necessary for the A/C.
It's entirely possible that the a/c would run on the appropriate sized
breaker, then again, maybe not.
Are there by any chance two sets of breakers for the unit. In the county
seat near me, code requires a second breaker located at or near the outside
unit. I assume this a safety factor so a technician working on the unit can
see and be sure that he has no power to the unit and that someone in the
basement hasn't flipped the breaker back on. Or maybe to foil the techs
tendency to work on a hot unit to avoid climbing up and down the stairs.
So, anyway, the practice around here is to oversize the outside breaker so
if there is a problem only the inside one flips off. I'm not an electrician
or HVAC guy but that's what I was told...I only sold the breakers.
