Has Your Electrical Panel Ever Been Checked?

Electrical panels are service boxes that house your main power line and distribute electricity to circuits throughout your home. They’re also known as load centers or breaker panels. A fire could be started if the panel doesn’t function as it should and sends too much electrical current through a circuit. 

The following electrical panels have either been recalled or are recommended to be replaced:

  •  Stab-Lok panels from Federal Pacific Electric (FPE) 
  •  Zinsco
  •  GTE Sylvania-Zinsco
  •  Eaton/Cutler or Challenger Electrical Equipment Corp. 
  •  Pushmatic 

Federal Pacific Electric: Stab-Lok

From the 1950s to the 1990s, FPE Stab-Lok panels were widely used in home construction. Stab-Lok panels, however, sometimes failed to trip when a circuit was overloaded, resulting in system overheating and the possibility of starting a fire.

In the early 1980s, the U.S. Consumer Product Safety Commission investigated Stab-Lok panels as a result of this problem. Even though FPE Stab-Lok panels have never been recalled, most experienced electricians advise removing them.

You can identify FPE panels in one of these ways:

  •  The metal cover bears the letters FPE, or Federal Pacific Electric
  •  Stab-Lok, Federal Pioneer Electric (FPE or Federal Pioneer Electric is written on an information sticker inside the panel) 
  •  Each switch has breakers with a red stripe


Many homes constructed or renovated in the 1970s have electrical panels made by Zinsco. These panels have several design flaws that pose a significant fire hazard, such as: 

  •  Shaky connections between bus bars and breakers 
  •  Aluminum parts that need to be replaced after 30 years
  •  Easily corroding bus bars
  •  Bus bars by integrating breakers

In addition, Zinsco panels might still be conducting electricity even if the breaker seems to be turned off. 

Since GTE Sylvania acquired Zinsco in 1973, you should search your electrical panels for the names listed below: 

  •  Zinsco
  •  Sylvania
  •  GTE-Sylvania
  •  Sylvania-Zinsco

You can also look for vivid red, blue, and green tabs on the individual breakers.  


Thousands of homes had Challenger electrical panels installed during the 1980s and the beginning of the 1990s, but they were recalled in 1988. The Challenger panels with 15- and 20-amp circuit breakers manufactured between February and April of 1988 were the subject of the recall. They have a mechanical component that can come loose and cause overheating, melting, and fire. 

Even after Eaton/Cutler-Hammer acquired Challenger, issues with these panels persisted. Eaton/Cutler-Hammer recalled 1,000 panels in 2014 due to the risk of shock from their easily accessible components. 

If you notice any of the following, you may need to replace your Challenger electrical panel: 

  •  Challenger is imprinted on the doorknob or handle.
  •  The manufacturer’s label for Challenger is on the inside of the panel door.
  •  There ar circuits with the word “test” written on one side and yellow buttons.

Be aware that other electrical panels, including those made by GTE Sylvania and Zinsco, can contain Challenger components. 


Pushmatic panels were used extensively from 1950 through 1980. The Pushmatic system wasn’t known to present any fire risks, but it’s now considered an outdated system that should be replaced. 

Pushmatic panels have rectangular buttons that activate and deactivate circuits, unlike most panels with right-to-left switches. 

Electrical Panel Safety

Never attempt to remove your electrical panel. Only a licensed electrician can repair or remove your panel. However, it’s wise to watch for warning signs that yours needs to be replaced, such as: 

  •  Rust
  •  Corrosion
  •  Signs of melting
  •  Insect damage
  •  Inadequate panel access
  •  Water or condensation
  •  Popping or crackling sounds
  •  A tingle or a shock when you touch the panel
