Federal Pacific Stab-Lok Panels

Federal Pacific Electric (FPE) panels were installed in millions of homes from the 1950s to the 1980s.

The problem

Testing has shown many Stab-Lok breakers may fail to trip during an overload. A breaker that doesn't trip can let wires overheat.

How to spot one

• "Federal Pacific" or "FPE" on the panel label
• "Stab-Lok" printed inside the door
• Breakers with red or black faces and thin toggles

What to do

Have a licensed electrician evaluate the panel. Replacement is the most common fix.
