This document describes how to identify Federal Pacific Stab-Lok® Electric Panels in buildings with special focus on the Federal NOARK Stab-Lok® Panelboard and the Federal NOARK Load Center. This is safety information for building inspectors, home buyers, home owners, electricians exploring the background of possible hazards associated with Federal Pacific Electric Stab-Lok® circuit breakers and service panels.
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. For more information see FPE REPLACEMENT PANELS and FPE REPLACEMENT BREAKERS. This page assists in identifying Federal Pacific Electric Stab-Lok® electrical panels and circuit breakers. More FPE information is in the links listed at Related Topics .

Here is what another model of the Federal NOARK Electrical Load Center looks like. (Some inspectors misreport this product as "Federal NOARC".)
Even before inspecting this electrical panel closely you can see the characteristic FPE Stab-Lok® circuit breaker red-painted toggle faces. The center black identification label in this Federal NOARC load center Catalog No. 116-68C is black painted.
Later FPE Stab-Lok® load centers painted white or other colored text directly onto the gray-painted electrical panel face.

Here is the unambiguous text which identifies this Federal NOARC load center as a Federal Pacific Stab-Lok® design and Federal NOARK Stab-Lok® LoadCenter Cat.No. 116-68C. |
