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.

The issue is this...lol

When I connect my christmas lights up through a very old extension cord to my outside sockets, and if it rains, the breaker being discussed trips quite a bit.
The diesel truck is also plugged in to the same outlet through the other extension cord that is just as old. In both extension cords, there are three new ends and one original.

At first, I suspected the breaker. But the breaker never trips the rest of the year. And it pretty much happens only when it rains.

That it needed to be replaced
Only that he was trying to identify it
I can explain it to you.
But I Can Not understand it for you !

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.


The standard breaker they are referring to is a GFI breaker.

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.
