If your home has a panel with "Federal Pacific Electric" or "FPE" stamped on the door, it is worth understanding exactly why this brand became the most commonly flagged panel in the country — and why the company that made it no longer exists.
A Brand Investigated by the CPSC — Then the Investigation Was Closed, Not Cleared
In the early 1980s, the U.S. Consumer Product Safety Commission opened an investigation into circuit breakers made by Federal Pacific Electric between 1960 and 1985, after reports of breakers failing to trip during overloads. CPSC-commissioned testing found that 51% of the breakers tested failed to trip during overload conditions, and failure rates on some circuit types reached 65% to 80% after repeated surges.
The CPSC closed its investigation in 1983, citing budget limits and the logistics of a nationwide recall — not because the panels were found safe. No recall was ever issued, which is part of why FPE panels are still sitting in homes decades later. We covered how this connects to current insurance non-renewals in Why Texas Insurance Companies Are Flagging Zinsco and Federal Pacific Panels.
Why a Breaker That Won't Trip Is Dangerous
A breaker's entire job is to cut power before an overloaded wire overheats. When it fails to trip, the wire keeps carrying more current than it is rated for, insulation heats up, and the risk of arcing or fire climbs. FPE's Stab-Lok breaker design is the specific mechanism investigators found prone to this failure.
Why Insurers Won't Touch Them
Most major insurers now decline new policies on homes with an FPE panel, and homeowners with an existing policy frequently receive a non-renewal notice once the panel shows up on an inspection report.
What To Do If You Have an FPE Panel
There is no retrofit or partial fix — replacement is the only real solution. Since FPE stopped production in the mid-1980s, every one of these panels still in service is at least 40 years old, well past the service life any electrician would recommend.
Corpus Christi's neighborhoods that grew during the postwar boom of the 1960s and 70s — along with older sections of Alice and Kingsville — still have a meaningful number of homes running original Federal Pacific panels from that era. If yours is one of them, don't wait for a tripped breaker to prove the point.
