Forgive me if this has been asked recently but I searched the forum and googled the 'net for a circuit breaker compatibility chart.
Has anyone documented what breakers will fit other manufacturer's panels? I'm talking residential.

Just because they fit doesn't mean that you can use them. If they are not from the original manufacturer, then they must be UL "classified" for use in that panel. All classified breakers come with a listing of panels that they are permitted to be used in. Use of breakers that "fit" but are not listed of classified for use in that panel is a code violation and a safety hazard.

OK. I'll rephrase the question.

Forgive me if this has been asked recently but I searched the forum and googled the 'net for a circuit breaker compatibility chart.
Has anyone documented what breakers are UL classified for use in other manufacturer's panels? Or is that generally not done?

I'm talking residential.

I don't know of any published list. The information is required to be on the classifed breaker or its package.

I was wondering the same thing. I know that Siemens and Murray are exactly the same and should be listed for each others panels since they are made on the same line, just diferent stickers. I know Siemens will fit in a GE, but a GE doesn't quite fit right in a Siemens. Square D homeline fits a Siemens, but Siemens doesn't fit a Homeline. Cutler Hammer makes a breaker specifically to fit a Square D QO, so I guess it's listed.

Our trucks are stocked with a wide array of breakers so we don't mix and match unless it's an obsolete panel, like Challenger, then we use a Siemens.

I really would like a list of "legal" breaker cross referrences.

I'm glad you agree with me. I'll post here if I find anything. Or maybe I'll research the subject and report my findings.

For electric eagle.
I think the proper replacement of challenger breakers is cutler hammer. Challenger was part of westinghouse and westinghouse became part of cutler hammer.

Just as an aside there, guys,
Over here in NZ, this very topic is a real sore point with us Electricians.
In that, competitiveness, between the Manufacturers of Switchboards/MCB's, is such that, the one manufacturer, will make thier board to only accept thier range of Breakers, it's all OK, until you go to fit the front panel back on the board, after you have finished the job, and they don't fit!.
They are all DIN Rail mounting, but the front pieces are slightly different in width.
Sure, you can rip the panel out, but why?.

Cutler Hammer has a line of breakers listed for use in alot of the more popular panels.
