4 recalled electrical panels

Electrical panels, sometimes called load centers or breaker panels, are service boxes that contain your main power line and distribute electricity to circuits throughout your home. If the panel fails to operate as expected, it can send too much electrical current through a circuit and cause a fire.

Old electrical panels are usually found during the home inspection before you buy, but inspectors can miss them. The following panels are considered out of date or have been involved in an electrical panel recall:

• Federal Pacific Electric (FPE) Stab-Lok panels

• Zinsco panels, also known as GTE Sylvania-Zinsco panels

• Challenger panels made by Challenger Electrical Equipment Corp or Eaton/Cutler-Hammer

• Pushmatic

Federal Pacific Electric

FPE panels were a popular electrical panel and were widely used starting in the 1950s through 1990. However, Stab-lok panels can fail to trip when a circuit is overloaded, causing the system to overheat and potentially ignite a fire.

This concern led the US Consumer Product Safety Commission (CPSC) to investigate Stab-Lok panels in the early 1980s. In 2011, the CPSC issued a press release stating it could not make a "determination as to the safety of FPE panels or the accuracy of of the manufacturer’s position on the matter."

While FPE Stab-Lok panels were never actually recalled, most electricians recommend removing them. Here are a few ways you may be able to recognize FPE Stab-loks:

• Federal Pacific Electric or FPE stamped into the metal cover.

• An information sticker on the inside that reads Federal Pacific Electric, Federal Pioneer FPE, or Stab-lock.

• Breakers with a red stripe on each switch.

Zinsco

Many homes built or updated in the 1970s, particularly those in the western portion of the county, have electrical panels made by Zinsco. Unfortunately, these panels have several design flaws that create a serious electrical panel fire hazard, including:

• Insecure connections between breakers and bus bars (the part that distributes power).

• Components made of aluminum that need to be replaced at 30 years.

• Bus bars that corrode easily.

• Breakers that melt into the bus bar.

Moreover, Zinsco panels may continue to conduct electricity even when the breaker appears to be off.

Zinsco was purchased by GTE Sylvania in 1973, so you want to check your electrical panels for the following names:

• Zinsco

• Sylvania

• GTE-Sylvania

• Sylvania-Zinsco

You can also look for bright red, blue, and green tabs on the individual breakers, but treat this as a rule of thumb. Zinsco electrical panels can also have black breakers.

Challenger

During the 1980s and early 1990s, Challenger electrical panels were installed in hundreds of thousands of homes, but they were recalled in 1988. That recall specifically focused on Challenger panels with 15- and 20-ampere circuit breakers made between February and April of 1988 that have a mechanical component that can detach leading to overheating, melting, and fire.

Unfortunately, problems with these panels continued even after Eaton/Cutler-Hammer purchased the Challenger. In 2014, Eaton/Cutler-Hammer recalled 1,000 panels because their easily accessed components presented a shock risk.

You may have a Challenger electrical panel that you need to replace if you see:

• Challenger stamped on the handle or door.

• Challenger on the manufacturer’s label (often found on the inside of the panel door).

• Circuits with yellow buttons and the word “test” on one side.

Please note that Challenger parts can show up in other electrical panels, including those made by GTE Sylvania and Zinsco.

Pushmatic

Pushmatic panels were popular from 1950 through 1980. During that time, the Pushmatic system wasn’t known to have any fire hazard, but it’s now considered an outdated system and should be replaced. Be forewarned that you can still buy new Pushmatic components. However, these parts may not be compatible with the original Pushmatic electrical panel.

Identifying a Pushmatic panel is relatively easy. Unlike most panels that have right-to-left switches, a Pushmatic has rectangular buttons that activate and deactivate circuits.
