Federal Pacific, Zinsco, Pushmatic: The Dangerous Panels Still Hiding in LA Homes
These panels look ordinary. They're also the leading cause of preventable electrical fires — and they're still in thousands of Los Angeles homes.
A quiet hazard in the garage
Walk into almost any Los Angeles home built between the 1950s and the early 1980s and you'll find a beige, gray, or brown breaker panel bolted to a wall. It looks ordinary. It has been quietly powering the house for 40 or 50 years. And in a large number of cases, it's one of three panel families that the electrical industry now considers unsafe at any age.

The three panels to look for
Federal Pacific Electric (FPE) "Stab-Lok"
- Manufactured roughly 1950s–1980s
- Silver or beige front, red trip strips on the breakers
- Independent testing has shown Stab-Lok breakers can fail to trip during an overload or short circuit
- Even breakers that appear in the "off" position may still carry power
Zinsco / Sylvania-Zinsco
- Manufactured 1950s–1970s
- Colored breaker handles (red, blue, green, yellow) on a shiny aluminum bus
- Breakers are known to fuse to the bus bar, meaning they can't trip when they need to
- Aluminum bus bars corrode and arc, sometimes melting into the panel
Pushmatic (Bulldog)
- Push-button breakers instead of toggle switches
- No main disconnect on many models
- Breakers stiffen with age and often fail to trip; replacements are extremely hard to source
Why insurance companies care
More and more homeowners insurance carriers in California will decline to write, or non-renew, policies on homes with these panels. If you're buying or refinancing, expect the inspector to flag it and the lender to ask for a replacement quote.
What a safe replacement looks like
Replacing a dangerous panel is not a "swap the breakers" job — the panel itself is the problem. A proper replacement includes:
- Full removal of the old panel and dead-front
- Installation of a modern 200-amp panel with copper bus and current-generation breakers (with AFCI/GFCI where code requires)
- New grounding electrode system and bonding
- LADWP-coordinated power drop and re-energize
- City of Los Angeles permit and inspection

What to do this week
- Open your panel cover (leave the dead-front alone) and look for the FPE, Zinsco, or Pushmatic name.
- If you see any of them — or you're not sure — schedule a free inspection.
- Don't "rely" on the panel just because it hasn't caught fire yet. That's the exact scenario these panels are famous for.
