In my home, I have a Square D service panel. I am changing one of the circuit breakers from a standard breaker to a GFCI type (the circuit is outside). I could not find any 15A Square D breakers at any of my local stores (Home Depot, Lowe's and a few electrical supply stores). Most stores carry 20A GFCI, but I need 15A.

I tried another brand (Murray), but it does not fit because the mounting on the back of the breaker will not seat properly as the "slot" is not long enough.

I have found some used breakers on-line, but I am not sure if this is a good way to go.

My questions:

Based on experience, is there a large risk in buying a used Square D 15A GFCI?

Can I use another brand and file the back of the case to seat the breaker?

Thanks in advance,

Joe

I assume you have the Square D QO Series. You have no choice but to use a Square D QO breaker, as these are unique. No others will fit, and no others are UL listed to fit.

If you have the HomeLine series, GE, Siemens, and Cutler Hammer sell UL Listed breakers that will fit in HomeLine panels.

Note, any breaker you use, other than Square D, must be listed to be installed in that panel.

I buy used and reconditioned breakers all the time, from reputable dealers that offer one year warranty. I cannot say what you may have if you get something from E-Bay, etc.

No, put the file away and back away from the breaker!!

That is never allowed. If there is a fire, an insurance carrier may call for forensic evidence, and if that breaker is found, somebody will have a lot of explaining to do.

Why the hang up on a 15 amp GFI? What size wire is the circuit? If it is #12, you can use a 20 amp breaker. If the circuit is #14, then your right, you have no choice but to use a 15 amp breaker.
