Federal Pacific Stab-Lok, Zinsco, and Pushmatic panel identification and replacement. GFCI, AFCI, grounding upgrades. Code-corrections from licensed Master Electrician.
If your home was built between the 1950s and 1980s, there’s a meaningful chance it has an electrical panel that has been documented to fail under load — meaning the breakers don’t trip when they’re supposed to. We replace these panels every week. Here’s how to identify them and what to do.
Federal Pacific Electric (FPE) Stab-Lok: Sold extensively from the 1950s through the early 1980s. Independent testing has shown a high rate of breaker failure. Many insurance carriers now refuse to insure homes with FPE panels.
Zinsco / Sylvania-Zinsco: Common in homes built 1955-1975. Known for breaker melting and failing to trip. Frequently associated with panel fires.
Pushmatic (Bulldog Pushmatic): Older push-button breakers, mostly 1950s-1970s installations. Reliability issues and parts availability problems. Often replaced for safety even when functional.
Don’t panic, but don’t delay. The risk isn’t imminent for most homeowners — people live with these panels for years — but the failure mode (breaker doesn’t trip during a fault) is exactly the failure mode that causes electrical fires. The fix is straightforward: panel replacement with a modern Square D, Siemens, or Eaton panel.
Cost in Austin runs $2,200-$3,800 for a like-for-like 100A replacement, $2,800-$4,500 for an upgrade to 200A service. Permits, inspection, and code-compliant arc-fault protection included.
If you’re refinancing or selling, your insurer or buyer’s inspector will likely flag an FPE or Zinsco panel as a condition of the transaction. This often forces emergency panel replacement on a tight timeline. We can sometimes provide a documentation letter showing the panel has been inspected and is functional, which buys time, but most carriers want it replaced.
Better to replace proactively on your schedule than reactively under transaction pressure.
