Project Showcase:
What Is a Zinsco Panel and Why Is It Dangerous?
Zinsco electrical panels were commonly installed in homes from the 1950s through the 1980s. While they were considered innovative at the time, modern research and field data have revealed serious safety issues.
Major Problems With Zinsco Panels:
-
Circuit breakers fail to trip when overloaded
-
Electricity may still flow even when breakers are switched off
-
Overheating and arcing are common inside the panel
-
High risk of electrical fires
-
Difficult to find replacement parts
-
Do not meet current electrical safety codes
🔥 Real Fire Hazards: Zinsco Panel Failure in Action
This image shows a real example of what happens when a Zinsco panel fails. These issues aren’t just theoretical — we see damage like this regularly in homes that haven’t been upgraded.
🏠 How This Affects Your Home (and Your Insurance)
If your home still has a Zinsco panel, you could be at risk in more ways than one:
-
Fire Risk: Breakers may not shut off during faults, leading to overheating and fire.
-
Electrical Code Violations: These panels are no longer approved under current codes.
-
Insurance Red Flags: Many insurers may deny or cancel policies for homes with Zinsco panels.
✅ What a Safe Electrical Panel Looks Like
A modern panel is designed with up-to-date circuit breakers that reliably trip during faults, reduce fire risk, and ensure your home meets all local electrical codes. Upgrading offers:
-
Better safety
-
Easier maintenance
-
Increased property value
-
Peace of mind
🔍 How to Tell If You Have a Zinsco Panel
Not sure if your panel is a Zinsco? Here are a few signs:
-
The name “Zinsco” or “Zinsco-Sylvania” on the panel or breakers
-
Brightly colored breaker switches (often red, green, or blue)
-
Breakers that are difficult to remove or don’t snap in like modern ones
