Federal Pacific Electric Stab-Lok Circuit Breaker Articles and Failures Research

Federal Pacific Electric "Stab-Lok" service panels and breakers are a latent hazard and can fail to trip in response to overcurrent, leading to electrical fires. The breakers may also fail to shut off internally even if the toggle is switched to "off." Some double-pole (240-Volt) FPE circuit breakers and single-pole FPE Stab-Lok circuit breakers simply do not work safely. There are other panel-defects independent of the breaker problems, panel and panel-bus fires and arcing failures in some equipment. The failure rates for these circuit breakers were and still are significant. In some cases failure to trip occurs 60% of the time - a serious fire and electrical shock hazard. Failures are documented in the CPSC study and by independent research. Additional independent testing and research are on-going and are reported here. FPE Stab-Lok electrical panels should be replaced. Do not simply swap in some replacement breakers.

• FPE Stab-Lok New Jersey Class Action Notice - 20 April 2005 Claims Deadline. The New Jersey Court document confirmed FPE cheating violated New Jersey Consumer Fraud Laws - Class Action Settlement Notice for New Jersey Residents. FPE was found to have committed fraud under the New Jersey Consumer Fraud Act. (Appeals are pending). "In a class-action lawsuit against FPE/Reliance in New Jersey, the Court found that Federal Pacific Electric Co. (FPE) committed fraud by representing that their FPE Stab-Lok(R) circuit breakers met the applicable (UL) standard test requirements when in fact they did not. The Court's finding of fraud, published in 2005, indicates that FPE cheated on the tests that were required to obtain UL listings. The company improperly applied UL labels to circuit breakers that could not and did not meet the UL requirements. FPE covered up the defective performance of the circuit breakers by a long-standing practice of fraudulent testing. The Court's finding helps resolve the question as to how the defective breakers got into the marketplace and into homes." -- 2007 FPE Stab-Lok TECHNICAL REPORT, p.1, Dr. Jess Aronstein [next linked-article below].
