Trying to identify a Breaker in my electric panel...

Hi,

I have a '91 airstream and on the lower breaker position is a GFI, ground fault breaker.

So the identifying marks on the actual breaker are:

************************
Type Q0 60/75 deg CWIRE
1 Pole Class A 120vac
Square D AL/CU #8-#14

Interrupting rating 10,000 amps

Max. RMS sym. 120 vac

series 2
************************

So its a Square D...
I went on the internet and did a bunch of searching, and, I found a breaker part number that might be it. But Im not sure. The first part number in the list seems to be a base part number and the ones after that seem to be breakers with special options. I have no idea what the options mean.

Partno. QO120GFI
Mini CB - QO - 20A - 1P - 120V - 10kA - Plug-in - GFI

Partno. QO120GFI35

    Replacing a GFI with a standard breaker without making the first outlet a pass through GFI outlet is a violation of electrical code, and makes for a very unsafe situation.

    If the breaier is a GFCI (has test button) I would only replace with another GFCI. there is a reason they use those.

    Check your local Home Depot or Lowes I think they both carry Square D breakers and panels. 84 Lumber may even carry them. Take it out, take a picture or take it with you and match it up.
