Are all Zinsco panels considered potential problems ?


When did they go out of business?

Yes.


They were bought out in the early 70's by Sylvania. They were phased out shortly after that.

Sylvania placed their name on the design without making any changes. The panel has the same external appearance.

When the cover is removed, it's obvious by the bus bars that it's the same failed Zinsco design.

Thanks Jeff !


I just remembered a GE plastic main panel on a townhome exterior built in 1995. It had all gas appliances so the service was 90 amps. The plastic panel had just one 90 amp C/B (rare?) that fed the interior sub panel.

These plastic GE panels should have been recalled since they start melting really easy.

Anyone know of any other recalled panels ?

recalled panels. Don’t make the mistake of telling a client that Zinsco or FPE have been recalled.


In fact, if you don't have supporting documentation, don't say "recalled." Simply state your recommendations.

Either didn’t find it, or not very good at searching… but is there any kind of authoritative source that documents the Zinsco panel problems?


Thanks!

For some reason articles about Zinzco’s problems are very hard to find. There are a few out there about FPE, but not Zinzco. The best I’ve found is in Electrical Inspection of Existing Dwellings, but it’s copyrighted material so I can’t quote it here. Even that isn’t a large article. Have you tried the inspect-ny site?


Jeff, how can you use a harsh, unforgiving word like "failed' to describe the Zinzco design? You're supposed to be PC in CA, no? That design was...um, "safety-deprived"....or "intelligence-deficient"....maybe even "arc-enhanced", but failed? Meanie!!! ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif)

I don't have any "supporting documentation" nor do I know if any exists. My recommendations are based on training, education and personal experience.

My training helped me to identify the panel board - my education made me aware of the potential problems - my personal experience has uncovered defects in 80% of the Zinsco panel boards I've come across.

My area is littered with these in many shapes and sizes. I inspect three or four a week.

If I do come across any documentation, I will be sure to post it for all. Maybe in a few more years, I'll have enough experience with these systems that I'll write my own "evaluation."
