In today’s modern homes, where high-powered appliances and cutting-edge technology are the norms, electrical safety is paramount. And when it comes to electrical safety, your panel plays an integral role. If you’re a homeowner, especially in an older property, you might have come across the Zinsco brand name. In this blog post, brought to you by Positricity – your trusted local electric company – we’ll dive deep into the world of Zinsco electrical panels, the risks they pose, and why considering an upgrade might be in your best interest.

A Brief History of Zinsco Panels

Zinsco was a popular electrical panel brand during the 1970s. Thousands of homes were fitted with Zinsco panels, touted for their cutting-edge features of that era. However, as time moved on and more became known about their durability and safety, concerns started to rise.

Why Zinsco Panels are a Concern

     1. Circuit Breakers May Not Trip

The primary function of a circuit breaker is to trip, or shut off, when there’s a fault or overload. Zinsco panels have been found to have breakers that may fail to trip, leading to potential fires or electrical shocks.

     2. Melting Components

Some Zinsco panels have been reported to allow the bus bar (a conductor inside the panel that distributes power to the breakers) to melt and fuse with the breaker. This not only prevents the breaker from tripping but can also be a fire hazard.

     3. Outdated Technology

Like all technology, electrical panel designs have evolved over the years. Newer panels accommodate modern electrical demands and offer more safety features.

Identifying a Zinsco Panel in Your Home

If you’re unsure whether you have a Zinsco panel, there are a few identifying features:

– The Zinsco logo: Often, this is a clear giveaway. Look for the name “Zinsco” on the panel.

– Unique colored breakers: Zinsco panels often have breakers in varying colors like green, blue, and red.

– The design and shape: Zinsco panels are distinctive with a certain retro look distinct from modern panels.

If you’re still uncertain, it’s always a good idea to call in an expert like Positricity to examine your electrical system.

Why Upgrade Your Zinsco Panel?

     1. Safety First

This cannot be emphasized enough. An electrical panel that doesn’t operate properly is a fire hazard and poses a risk of electrical shocks.

     2. Home Insurance

Many insurance companies are wary of Zinsco panels. Upgrading could mean a reduction in your home insurance premium.

     3. Increase Property Value

If you’re considering selling your home, an upgraded electrical panel is a solid selling point. Prospective buyers are likely to appreciate a home with a modern, safe electrical system.
