FPE Circuit Breaker Replacements: this article gives expert advice about replacing FPE Stab-Lok® circuit breakers - Federal Pacific Electric Stab-Lok® breakers and discusses how to repair FPE StabLok Panels and circuit breakers for actual improvements in electrical safety.
Replacement FPE Stab-Lok® circuit breakers are unlikely to reduce the failure risk of this equipment. We recommend that residential FPE Stab-Lok® electrical panels be replaced entirely or the entire panel bus assembly be replaced, regardless of FPE model number or FPE year of manufacture. We do not sell circuit breakers nor any other products.

Homeowners and renovators who encounter these panels should replace the entire panel and circuit breaker set with new equipment. Panel replacement, can involve significant expense, typically $800 to $1800 depending on service size and other factors.
Do not simply replace individual FPE Stab-Lok® circuit breakers:
1. No Evidence of Improved FPE Stag-Lok Replacement Circuit Breaker Performance
First of all, there is no data suggesting that new stock, replacement FPE breakers, or "new old stock" FPE breakers found in storage somewhere perform any better than the ones already in the FPE Stab-Lok® panel. In fact, limited testing of replacement FPE Stab-Lok® circuit breakers also detected failures to trip in response to overcurrent conditions. In at least some cases, replacement circuit breakers are manufactured in Asia as copies of the original, problematic breaker design, as we discuss at #3 below.
2. Other FPE problems besides circuit breakers
FPE Second, there are other functional and safety concerns in the panel besides the breakers themselves. We've seen panel bus damage, panel bus meltdowns, and failure of breakers to remain secured in or onto the connecting bus itself.
See REPLACEMENT PANELS for some panel replacement alternatives that might reduce the repair cost.
For several reasons We do not recommend attempting to "repair" an individual failed Stab-Lok® breaker by buying a replacement either from used stock, new stock, or "compatible" stock:
4. A few other warnings about things people try to reduce the hazards of FPE Stab-Lok® Breakers:
In sum, if you could replace all the FPE Stab-Lok® equipment with (somehow magically obtained) all "new" FPE Stab-Lok® equipment (found in a used-or new-old-stock warehouse for example) the risk level for the building would not be sufficiently different from before the replacement and would remain high: there remains a latent risk of fire from failure of these breakers to trip in response to overcurrent.
5. Replacement Federal Pacific Electric FPE Stab-Lok® Panels is Recommended
For some cost and method alternatives when replacing an Federal Pacific Electric Stab-Lok® Panel or "load center" see REPLACEMENT PANELS which describes conventional Option#1 - "remove and replace" the electrical panel and Option#2 - FPE Load Center Replacement using Cutler Hammer (CH) Adjustable Retrofit Kit
