How can I Identify if my Home has a Federal Pacific Electrical Panel?

Identifying a Federal Pacific electrical panel is a visual process that any homeowner can perform by looking for specific brand markings and design characteristics. These panels, which were commonly installed between the 1950s and the early 1980s, are widely recognized for significant safety risks due to design flaws.

To determine if your home has one of these units, look for the following clues:

• Check the Brand Name: Look for “Federal Pacific Electric” or “Federal Pacific” printed on the panel door or the interior cover label. Even if the sticker is faded, the name is often still legible.
• Identify Stab-Lok Branding: Examine the circuit breakers themselves. Federal Pacific used a proprietary design called Stab-Lok, which is typically stamped directly on the face of the switches.
• Observe Breaker Colors: These breakers often feature a distinctive bright red or dark gray casing and a visible metal stab clip that locks into the bus bar.
• Verify Model Numbers: On the rating sticker inside the panel door, look for model numbers that begin with the prefix “FPE” or explicitly include the name “Federal Pacific.”
• Note the Main Breaker: Some older models may lack a main breaker entirely, which can confirm the panel’s vintage and indicate outdated safety features.

Because of the documented failure rates of these systems—especially in coastal environments like Marina del Rey where salt air can accelerate corrosion—visual identification should always be followed by a professional evaluation. If you identify any of these markings, we recommend scheduling an Electrical Safety Inspection with a licensed professional to assess the risk and discuss Electrical Panel Upgrades to bring your home up to modern safety standards.
