Connecticut Electric UBIF0250N FPE Circuit Breaker, 2-Pole 50-Amp Thin Series

Expensive but had to replace to satisfy insurance guy. Not a problem. (the original had been in there since 1954 and never failed but Hey you can't argue with insurance policy so I replaced it. Then the agent said I'd have to have it redone by a professional where I kind of blew up. I showed her my MSEE from Cal Tech, My Journeyman ticket from the IBEW and my 40 year old city license. Still she balked so we just changed insurers. So really I don't know if I had to do this or not. There was a report out of Florida where they said that 60-80% of FPE breakers failed when the normal rate is .01%. I think that was bunk. 60-80% failure rate would mean a chicago fire in every town in the USA and that didn't happen. Actually statistically it is not significantly different than any other breaker made in the 50s and 60s. Anyhow, I have a new breaker, I hope it is as good as the original. My only complaint is that it is quite expensive.

This lasted about a year. Bought it last summer for to charge my Car. I use it only on weekends during the summer at my cottage, so I can safely say at most about 100days of use so far and the breaker keeps tripping. Electrician says the breaker is defective and everything else is fine, so I am buying a proper Stablok breaker at HomeDepot.ca for 125$ delivered to my door.

I required a 2 pole 50 amp stablok breaker and it worked great.

I haven't applied more than 50A to it, so don't know if it'll kick or not. But so far it appears to be doing the job.

The Federal Pacific breakers are simple and same as any other breaker. Well built and functional. Unfortunately if you complain about warehouse deals being bad sometimes they do not post your review. So I post my review on other sites. The wire screws are not very secure and vibrate out easily so two breakers were missing one screw bolt each and it is very hard in Canada to find one that fits properly
