External Breaker for Home A/C


My A/C unit’s external power/breaker box has a bad circuit breaker. It is an older style “Stab breaker” (I think that is what you call it...see picture).

Bottom line: I am wondering if the path of least resistance for me is to simply find a compatible replacement breaker (since I’m not sure how to connect the wires in a new Eaton Box). Would it make sense to just replace the breaker? (presumes one can be found).

There are 3 conduits connected to the box.. 1 conduit carries the wires from the main power, another goes to the outside A/C unit itself, while the 3rd conduit carries the wires that go to the air handler in the basement.

Thanks for your thoughts on this. Here are some pictures of my situation.

That one says made in China so thinking it is newer and was replaced already. Bramec is a supplier of replacement breakers.

Current replacement: https://www.amazon.com/UBIF230N-Elec.../dp/B000VYNPXE

You have an unusual and non-code install. There are two wires per terminal which breaker wasn't rated for. Have to do a full review of what you have to determine what a compliant solution would be. Probably need to run new wires from the panel splitting the inside from outside loads.

I would agree with that.

There should be 2 double pole breakers there. A 2P15 and a 2P30 at the very least and technically the air handler should not be connected to that disconnect.
