Federal Pacific Electric (FPE) and Zinsco panels have design flaws that can cause their breakers to fail, creating a safety hazard. If you have either of these panels, we recommend replacing it with a new, UL-Certified panel.
How to tell if you have an Federal Pacific Electric (FPE) or Zinsco Panel:
Federal Pacific Electric: Homes built between 1950 and 1990 may have Federal Pacific Electric (FPE) panels with Stab-Lok circuit breakers. To check if you have an FPE panel, look in your panel for a Federal Pacific label or logo, which will usually appear on the front cover. Inside the panel, look for a “Stab-Lok” label near the center or side of the panel. The breakers will have a signature red strip running across their front.
Zinsco: Homes built between 1963 and 1981 may have Zinsco panels. Look a label stating “Zinsco,” “Sylvania,” or “Magnetrip.” Zinsco panels also have a signature red, green, and blue toggles on their circuit breakers.
