Hello Electrical Experts,
I have a Challenger Panel and need to add a double breaker 40amps for a mini-split system (240 volt).
Are there different qualities of breakers? E.g. the Home Depot breakers might be for cheap construction/etc.
How do I know that the breaker is the correct dimensions compatible with the panel.
Cutler-Hammer and Eaton seems to be a common recommendation.
Below are pictures of the panel sticker and currently working breakers for my air compressor and an unused breaker.
Thanks.
