Safety Concerns Regarding Zinsco Panels

As a homeowner, you rely on your electrical panel every single day to keep your lights on, your appliances running, and your family safe. But what if the very heart of your electrical system is a well-documented fire and electrocution risk? For many homes built between the 1950s and the early 1980s, this is a dangerous reality. The culprit? Outdated and unsafe electrical panels, most notably those manufactured by Zinsco.

At Gilwee Electric, your safety is our number one priority. We believe in empowering homeowners in Placer and Sacramento counties with the information they need to protect their families and their investments. Here’s what you need to know about the risks of Zinsco panels and why a simple inspection can prevent a catastrophe.

What Are Zinsco Panels and What Makes Them So Dangerous?

Zinsco electrical panels were a popular choice for builders for several decades. Unfortunately, a critical design flaw has since come to light. The circuit breakers within these panels can become fused to the panel's main bus bar.

This means that even when a breaker "trips" during a power surge, the connection isn't actually broken. Electricity continues to flow, superheating wires and creating a severe fire hazard. Worse yet, the breakers can appear to be in the "off" position, giving a false sense of security while the circuit is still live, posing a serious risk of electrocution.

The key dangers of Zinsco panels are:

• Failure to Trip: The breakers don't reliably trip during an overload or short circuit.

• Melting and Fusing: The breakers can melt, fusing themselves to the panel and preventing them from shutting off power.

• Fire Hazard: Uncontrolled electrical flow can overheat wiring inside your walls, leading to a fire.

• Electrocution Risk: A breaker may appear to be off when it is still conducting electricity.

The Insurance Problem: A Major Hurdle for Homeowners

Beyond the immediate safety hazards, owning a home with a Zinsco panel presents a major financial and logistical problem: most insurance companies will not insure these homes.

Insurers view Zinsco panels as an unacceptable liability. Because of their documented history of failure and non-compliance with modern electrical codes, the risk of a catastrophic electrical fire is simply too high. When an insurance inspector identifies a Zinsco panel, you can expect one of the following outcomes:

• Denial of Coverage: A new policy will be outright denied.

• Non-Renewal: An existing policy may not be renewed.

• Increased Premiums: In rare cases where coverage is offered, it often comes with significantly higher premiums.

• Mandatory Replacement: The most common requirement is that the panel must be replaced by a licensed electrician before coverage can be issued or continued.

Failing to disclose the presence of a Zinsco panel can also lead to the denial of a claim if a fire does occur, leaving you financially responsible for all damages.

How to Check if You Have a Zinsco Panel

You may be able to identify a Zinsco panel yourself, but under no circumstances should you ever open the panel or touch any of its internal components.

Look for the following signs on the exterior of your electrical panel:

1. The "Zinsco" Brand Name: The name is often printed on the panel door.

2. GTE-Sylvania Branding: The panel may have been rebranded, so look for this name as well.

3. Colorful Circuit Breakers: Zinsco was known for using brightly colored breakers (red, green, blue, yellow).

If you see any of these signs, or if you simply have an older home and are unsure about your panel's history, it's crucial to have it professionally inspected.
