What is a Zinsco Panel, and Why Should You Replace It?

Protecting Sacramento Homes, One Upgrade at a Time

If your home was built between the 1950s and 1970s, you may have a Zinsco electrical panel without even knowing it.
While they were popular decades ago, today Zinsco panels are known as one of the most dangerous and outdated electrical systems still found in homes.

At Peak Electrical Contractors Inc., we specialize in Zinsco panel evaluations and insurance-approved replacements throughout Sacramento.

Here’s what you need to know.

What is a Zinsco Panel?

Zinsco was a major electrical panel brand installed in thousands of homes between the 1950s and 1970s.
At the time, they were considered modern — but design flaws have become dangerously clear over the years.

Why Are Zinsco Panels Dangerous?

  • Breakers May Fail to Trip: Breakers can appear "off" but still allow electricity to flow, creating a massive fire hazard.

  • Bus Bars Corrode and Overheat: Aluminum components inside the panel can deteriorate, leading to overheating and potential fires.

  • Melted Breakers: Breakers can fuse to the bus bar, causing loss of control over electrical circuits.

  • Not Code-Compliant: Zinsco panels no longer meet modern NEC (National Electrical Code) safety standards.

In short — Zinsco panels pose a serious risk to your home and family.

How to Tell If You Have a Zinsco Panel

  • Look for the brand name “Zinsco” or “Sylvania” (certain models) inside the panel door.

  • Breakers are typically colorful (red, blue, green) with distinctive thin switches.

  • If you’re unsure, Peak Electrical Contractors Inc. can inspect and identify your panel safely.

Can Insurance Cover Zinsco Panel Replacement?

In many cases, yes.
Because Zinsco panels are recognized as high-risk, insurance companies often approve panel replacement as a covered upgrade.
