What are Federal Pacific Stab-Lok Panels?
Federal Pacific Stab-Lok panels were commonly installed in homes across the United States between the 1950s and the late 1980s. Recognizable by their distinct red-tipped breakers, these electrical panels were manufactured by Federal Pacific Electric (FPE), a company that was one of America's largest producers of circuit breaker panels during this period.
Millions of homes built primarily between 1950 and 1990 contain Federal Pacific StabLok panels. During their peak, builders favored these panels due to their affordability and widespread availability. However, what initially seemed like a cost-effective electrical solution soon became a significant safety hazard for homeowners.
The Recall and Safety Concerns
Federal Pacific Stab-Lock panels gained notoriety for a troubling issue: breakers frequently failing to trip during circuit overloads or short circuits. When breakers fail to trip, they do not provide the critical safety mechanism intended to prevent overheating and fires.
Investigations into these panels revealed that approximately 25% of the breakers failed basic safety tests conducted by independent safety organizations. These results led to class-action lawsuits, and ultimately, a recall and discontinuation of these products. However, despite these findings, a formal nationwide recall by government safety agencies was never enforced, leaving millions of potentially hazardous panels still installed in homes today.
What Makes Them Dangerous?
Breaker Failure: The most severe problem is the breakers' inability to trip properly. This significantly increases the risk of electrical fires.
Electrical Fires: Due to their failure rates, homes with these panels are estimated to be significantly more likely to experience electrical fires compared to homes with more reliable breaker panels.
Insurance and Resale Issues: Many insurance companies refuse coverage for homes containing Federal Pacific panels, or they may require replacement before issuing or renewing homeowner's insurance policies. Home inspectors like Trinity Home Inspections always flag these panels as hazardous.
