A friend and I recently did some bartering. My drywall hanging/ finishing in a new bathroom for his electrical expertise. He is changing out one of our subpanels putting in a new panel and breakers. Also hooking up a generator switch in the barn.
We have one of these been wanting to get replaced
Zinsco Panels
Zinsco or GTE-Sylvania panels were popular electrical panels installed in homes throughout the 1970s. Zinsco is now defunct, but many homes still have these panels.
Why they’re unsafe: The circuit breakers inside many Zinsco panels melt to the main ‘bus bar’. This means the breaker can’t ever trip, even when there’s a short or overloaded circuit. So if there ever is a short or other problems, the surge of power melts wires and starts fires in your home.
How to tell if you have one: The name Zinsco anywhere on the panel is a sure sign it should be replaced. Also, many GTE-Sylvania or Sylvania panels are simply re-branded Zinsco panels or contain the problem Zinsco design. These should also be replaced.
However, not all Sylvania and GTE-Slyvania branded panels are dangerous. So if you have one, an electrician will need to inspect it to see if it has the problematic design.
