Electrical Wiring in the Home/Warm breaker


Hi. I have a Gould 100 amp breaker panel with a double pole main breaker. One of the poles on the main breaker will get slightly warm when my central air has been running for a while. I am aware that a hot breaker is dangerous, but I've read differing opinions on a warm panel. The temp here has been very high, so the ac unit has been running almost continuously and the panel gets more than slightly warm. It has also never tripped. The unit itself is a 13 SEER 3 ton Goodman.

Does this sound like something I should be concerned with or is this something to be expected with a lower amp breaker box? Also, why would only one pole of the main breaker get warm?

Thank you for your help.


Overheating is frequently caused by loose wires that are arcing. It also happens in older equipment due to age.  It's hard to say at exactly what point it should be replaced, but it should be replaced. The more of a load, the more it will overheat. I would keep a close eye on it, and replace it as soon as you can.
