Federal Pacific Electric Panels

If your home was built between 1950 and 1990 and is equipped with a Federal Pacific Electric (FPE) circuit breaker panel with Stab-Lok circuit breakers, you run a significant risk of breaker malfunction and fire.

The breakers inside the panel are designed to guard your home against serious electrical problems by preventing circuit overload, short circuits and outside power surges coming into the panel. When an overload occurs, a breaker protects you by tripping, thus shutting down the power to the circuit. However, if a breaker is defective or not operating properly, the risk of fire to the panel and consequently to your home becomes imminent.

Why are Federal Pacific breaker boxes dangerous?
Multiple tests done on the breakers since the 1980s have proven that one in four Stab-Lok breakers are defective and will not properly trip off. Unfortunately, when the testing began in the early 1980s, a New Jersey court later ruled that FPE committed testing fraud and a cover-up, labeling the breakers as meeting the standards set by the UL when in reality, they were defective.

In 1983, the Consumer Product Safety Commission closed its two-year investigation and felt it impossible to create a product recall at the time because of budget issues, even as Federal Pacific panels and breakers continued to be installed in millions of homes that to this day still run the risk of an electrical fire. An estimated 2,800 fires each year directly result from Federal Pacific panel breaker malfunction. Federal Pacific Electric has been out of business for many years, but the danger and damage caused by their negligence continues.

Do you have a Federal Pacific panel?
If you own a home between 25 and 65 years old, check your breaker box. A Federal Pacific panel will usually have its name or logo on the front cover. Inside, you will find the name Stab-Lok printed near the center or side of the panel. The intact breakers will have the signature red strip that runs across the front.

If you find you a Federal Pacific panel or Stab-Lok breakers, call a licensed electrician in your area for further information about replacing your circuit breaker panel.

Federal Pacific Electric Company (FPE) was one of the most common manufacturers of circuit breaker panels in North America from the 1950s to the 1980s. Millions of their panels were installed in homes across the country. Yet, as the years passed, electricians and home inspectors often found Federal Pacific Electric panels failed to provide proper protection to homeowners and their families. Experts now say that FPE panels can appear to work fine for years, but after one overcurrent or short circuit, they can overheat and become fire hazards.

In a class action lawsuit, a New Jersey State Court ruled that the Federal Pacific Electric (FPE) Company “violated the Consumer Fraud Act because FPE knowingly and purposefully distributed circuit breakers which were not tested to meet UL standards…”  An expert who investigated the potential hazards of Federal Pacific Electric panels stated under UL 489 test conditions, that FPE panels fail to trip at a much higher rate than standard panels.

When a breaker fails to trip, an extreme amount of power from the outside electrical supply surges into a home’s panel and circuits. Once that happens, it cannot be stopped or shut off manually. Electricity will burn until it runs out of fuel or the wires melt. The panel could overheat and catch fire, causing serious harm to a home and its occupants. Many Federal Pacific Electric panels and breakers can operate properly for years. But if and when they do malfunction, a disaster could occur.
