IDENTIFY Kearney or Zinsco Sylvania Electric Meter Base & Main Switch Combo

This website discusses the electrical, fire, and shock hazards associated with Zinsco electrical components, circuit breakers, electrical panels, including certain Sylvania electrical panels and breakers which are in fact of the same product design and origin.

Above, courtesy of Judd Stiff, we include photographs of a Zinsco-Sylvania electric meter base. At the right of our left-most photo (above left) you can see the interior of the Zinsco main service disconnect switches.

At our closeup (above right) you can see that the electric meter connections have overheated and look burned.

Below is a close-up photograph of connections in a Kearney electrical meter base.

Sean

Unfortunately, yes, that's a Zinsco-Sylvania panel design. Notice those two vertical strips that connect to two deep slots in the circuit breaker?

That identifies this as a Zinsco design. Above I post a closer-view excerpted from your photo. There we show the key identifcation points to confirm the Zinsco breaker design.

On 2020-07-04 by SeanN - I don't think this is the bad Zinsco panel - is that right?

...

Thank you for all the information - I don't think this is a Zinsco panel, but would you be able to confirm?

Model# is MT12MBB and House was built in 1977 in San Mateo County, California, USA.

I'm looking to upgrade to 200A with solar system in future but trying to decide if I should replace it now if it's unsafe.
Please see attached - Thanks!
Sean
