Refurbish CB in the field?

I am working on a project which includes replacing many FPE Stab-lok circuit breaker panels in apartments. Not a problem, we have done tons of these.

The oddball on this project is the (5) FPE main circuit breaker/CT cabinet assemblies. One main CB was "done" under phase 1. The p-touch label above the CB says the "300A circuit breaker refurbished and tested 6/20/2015". Since the management has changed as of 12/31/15, there is little or no history available. But I am skeptical that the circuit breaker could be refurbished in the field, and if so, if there is any value to this. I'm also skeptical that it was tested to any sort of standard. But again, no access to historical documents or folks.

Stab-lok CBs are notoriously unreliable. But I'm not a concerned with a larger (300A) frame molded case CB by FPE, and feel they should be left alone, or if we do anything, replace them entirely.

Any thoughts?

FPE breakers are notorious for not tripping when needed

there are professional refurbish companies. Many belong to PEARL.
They have standards for such too.

Yet, the P-Touch labeling would make me think it was not a professional job like that.

There are a lot of "breaker brokers" who resell used breakers and call them "refurbished" by just blowing them out with an air hose and wiping them down with WD-40. There really isn't anything else you can do to a molded case breaker, they are not designed to be taken apart. The only difference with a PEARL shop's process is that they will test it and certify it, which would mean a seal stating that. No seal, no testing. Just a blow-and-go.

I am a bit unclear as to the label. It is my understanding there is a P touch label placed above the breaker, like on the panel cover. Something a EC may do to let others know that a refurb was installed.

also I have seen 300 amp breakers that are not riveted together.

that was my take as well. I figured the label was there to note that a refurbished breaker had been installed, not that it had been refurbished by someone in the field.

No, it's not a test/maintenance firm's label, and it does not say the breaker was replaced with a refurbished one - it just says the braeker was "refurbished and tested". I agree with posters above - I'm not sure there is any refurbish that can happen to a MCCB (at least not without sending it to the factory), and especially on an FPE breaker (no more factory...).

I am going to recommend that the breakers be retrofit with new CBs (which will probably require custom buss fabrication to suit the FPE enclosure), or they just be left alone. "Refurbishing" them is IMO a waste of time and money.

Thanks all.

maybe it was sent out to be refurbished and tested. it does not make much sense that someone would go to the trouble to make a label that provides false information.

I would not be doing any custom buss work inside of an existing panel board. If you are convinced the main needs replacing, maybe it is better to just replace the whole thing. Will probably cost less. Or remove the main from the panel board and add one externally.

This is from PEARL:

Finally, the application of the Blue reconditioning quality seal is affixed in testimony to this device being treated to and passing all necessary tests required by the referenced standard and will operate in a Safe and Reliable way as intended by the original equipment manufacture at the time it was made.

Looks like this:

Exactly! Could not have said it better.

My recommendation would be to have these properly tested, if it fails replace it with a new one or at least one that comes with a certified test report. I can't help much more without knowing the breaker type but there may be other than FPE replacement options as well (Might require different mounting hardware)

What is the breaker type and panel type? You shouldn't need any custom bus, just the right kit.

you are not allowed to use them at all, or can't install them in new installations?

it seems odd they would allow a CB that has never been refurbished but not to allow one to send it off to be refurbished and tested.
