All info I read about Federal Pacific Stab-Lok panels reference 1982 and older panels. Are the newer panels different and considered to be safer?
I do home inspections and I always throw up a red flag and recommend replacement of any and all FPE stab-loc panels manufactured prior to 1984. After a federal investigation that ended in a very shallow "Duh, we don't really know" kind of conclusion.
FPE panels kinda disappeared for awhile. I'm not sure if they were bought out or retooled, but the newer panels and breakers do have a legit UL listing. In my opinion (backed with 40 years experience), if yours is pre-1983, replace it. A new GE, ITE, etc. panel is not that expensive and you can sleep easier knowing you don't have a questionable electrical distribution in your home.
