If your home has a Federal Pacific Electric (FPE) Stab-Lok panel, then you may be wondering what all the concern is about. We frequently come across these panels in older homes, and they always raise a red flag on our reports.
While FPE panels may look a lot like any other electrical panel, the history behind them tells a different story—one that has led electricians and safety experts to recommend their replacement.
The Issue with Federal Pacific Stab-Lok Panels
Federal Pacific Electric was one of the most common electrical panel manufacturers from the 1950s through the 1980s. Their Stab-Lok panels were widely installed in homes across the country and can be easily identified by their red-tipped breakers. However, decades of testing and real-world failures have revealed a dangerous flaw: many FPE breakers fail to trip when they should.
Circuit breakers are designed to shut off power when a circuit becomes overloaded, preventing overheating and potential fires. Unfortunately, studies have shown that FPE Stab-Lok breakers may fail to trip up to 60-80% of the time under testing conditions. This means that when an electrical fault occurs, the breakers may not shut off power, leading to overheating wires and a potential fire hazard.
Real-World Example: A House Fire Caused by Stab-Lok Breakers
A tragic example of the dangers of Stab-Lok panels occurred in Poughkeepsie, New York, in 2010. One of the breakers failed to trip during a ground fault event, allowing the wires to overheat and ignite surrounding materials. This failure resulted in a fire that quickly spread and caused extensive damage to the home.
Fortunately, the family escaped the house unharmed, but a subsequent investigation confirmed that the Stab-Lok breaker had contributed to the fire by failing to cut off the electrical current when it should have.
This is just one of many documented cases where an FPE panel failure led to catastrophic property loss—or worse. Electrical safety experts and fire investigators have linked these panels to numerous house fires over the years, reinforcing the urgency of replacement.
History of the Problem
Concerns about Federal Pacific panels have been raised for decades. In the early 1980s, an investigation by the Consumer Product Safety Commission (CPSC) found that Stab-Lok breakers failed key safety tests. However, due to budget constraints, the CPSC never issued an official recall. Independent research, however, including studies by electrical engineers and safety experts, has continued to confirm the risk.
One of the most significant findings came from a class-action lawsuit in New Jersey that determined Federal Pacific Electric had knowingly violated testing standards and sold panels that did not meet safety requirements. As a result, electricians across the country widely advise replacing these panels rather than attempting repairs.
Why You Should Upgrade Your Federal Pacific Panel
If you have a Federal Pacific Stab-Lok panel in your home, here’s why replacement is strongly recommended:
- High risk of electrical fires: The failure rate of Stab-Lok breakers makes them a serious potential hazard.
- Inconsistent performance: Even if the breakers appear to work when tested manually, they may not trip when an actual overload occurs.
- Insurance concerns: Some insurance companies may refuse coverage or charge higher premiums for homes with Stab-Lok panels.
- No safe repairs: Replacing breakers within an FPE panel does not fix the underlying design flaw.
What Should You Do?
If your home has a Federal Pacific panel, it’s best to have a licensed electrician evaluate and replace it. While replacing an electrical panel comes with a cost, the peace of mind and safety benefits far outweigh the risk of an electrical fire.
