Zinsco (and Sylvania-Zinsco) panels are known for breakers that fuse to the bus and fail to trip. Replacement costs $1,500–$4,000. If your panel says Zinsco, book an assessment now.Typical installed cost: $1,500–$4,000
Zinsco panels, common in homes from the 1950s–70s, use an aluminum bus design that corrodes and lets breakers weld themselves to the bus, meaning the breaker may never trip, no matter the fault. Like Federal Pacific, this is a replace-not-repair panel.
About Zinsco Panel Replacement
Zinsco (later Sylvania-Zinsco) panels have a quieter reputation than Federal Pacific but the same bottom line. Their aluminum bus bars corrode and pit; breakers clamp onto that bus and, over years, can literally weld themselves to it. A welded breaker conducts happily, and never trips.
The visual signature is deceptively cheerful: slim breakers with turquoise, red, and blue handles. If you see them, the panel predates 1980 and carries the design flaw. Replacement is the fix, one day, full modern protection.
Zinsco failure pattern
- Aluminum bus corrosion at the breaker connection
- Breakers that overheat, melt internally, or fuse to the bus
- Failure to trip under overload, the silent hazard
- Burn marks visible when breakers are removed (we photograph everything)

Look for 'Zinsco' or 'Sylvania' on the label and colorful (often turquoise/red) slim breaker handles. We verify it during a free assessment.
No, the failure is the bus design itself, not individual breakers. Replacement breakers inherit the same connection problem; a new panel is the only real fix.
General home inspections often note the brand without opening the panel. The damage lives at the bus connections behind the breakers, visible only during an electrical inspection, and progressive over time.
