Problems with Zinsco Electrical Panels

We have had customers calling us for years here in Northern California with problems they are experiencing with their Zinsco electric panel. These panels have been causing problems for a long time now and a lot of people consider them a hazard. It has definitely become a confusing subject because problems with the Zinsco panels cannot be seen by the naked eye. Problems of this nature even go a step further, because even with the panel cover removed and everything working fine, you STILL might not be able to discern that there is a problem. Lots of times an electrician will try to remove the breakers from the box only to find out that they are welded together and cannot be removed. In a situation like this, a breaker would be unable to trip, which is definitely an electrical problem to say the least.

With problems concerning electrical panels, and more specifically, Zinsco panels, please have a certified, qualified and most importantly licensed electrician handle this job. The breakers inside the panel may even appear to be off but meanwhile and still in fact conducting electricity.

These Zinsco panels were manufactured back in the mid 1970’s and most electrical experts say that they would not pass code in today’s standards.

Some of the problems include:

-The panel containing aluminium

-The connection of the breaker to the bus bar is often not solid

-It seems the bus bar corrodes quite easily

-Breakers may appear to be off when they are actually not


I don’t think that I need to go into very specific details about why each of these scenarios can pose a great threat to your home or business.
