Hi all

I have a used FPE 3 Pole Bolt On Breaker I am trying to determine the amperage of.
The white "amps" number is totally gone from the handle. The little CSA sticker is readable but from what I can see from other three pole breakers I have of the same as per se vintage, are all the same, they don't appear to identify the amperage.

Does anyone know where I can find out the amperage of this breaker?

Thanks in advance

I don't think you could without some sort of load testing equipment. Replacement is your best route. What wire size came off it?

Hey Tim. I assumed load testing devices would be required. The wire size would have been an indicator for sure but this breaker came out of a big box of FPE breakers that had been sitting on a shelf in the work shop of a long term client. I am cleaning them up from about a decade of dust to put them up for sale, hence my original question. Thanks for responding.

I'm hanging onto some newer FPE breakers (white housings, Schneider-made), just in case. All the handles have molded -in amperages, so I'm not sure what to think other than you've got a very old breaker. Probably best to toss it.

As far as I know, the 3 pole FPEs worked ok.

If possible, rent a breaker test set, that way you could tell what it trips at.........or even if it trips at all......lol.

How about a pic of the lugs?
also, there is such a thing as a non-rated switch

Non rated? How’s that work?. I never noticed it mentioned in the NEC

Send it to me along with the rest of the CB's I'll test them. Megger, high current (long time instantaneous) too small to ductor/microhm most likely.

I pretwist and then use wire nuts. Solder pots rule.

The old NE frame had the amperage as part of the model number
Good breakers also..

Some breaker frames are just a simple switch without a trip unit.
Square D makes these in 2 and 3 pole, 30 and 60 amp plus 3 pole 100 amp, not sure about the 2 pole.

I use these once in a while as a disconnecting means in a 2 or 3 circuit panel when I don't want overcorrect, short circuit or ground fault protection.
