    Default A good Zinsco???

    After an inspector called out a Zinsco panel for replacement, a licensed electrician evaluated it and called it "perfect." He even put it in writing. Homeowner said that there are Zinsco's that are good and this is one of them. I am dubious.... DSCN3066.jpgDSCN3067.jpg

    I was under the impression that all Zinsco with multi-colored breakers were suspect and then when Sylvania bought Zinsco even thoses were flawed. Does anyone know if there are acceptable Zinsco's???

    To my knowledge there are no "Good" Zinsco panels/breakers or Sylvania ones that used Zinsco breakers. I suppose some were slightly better than others. As far as I know they do not make a UL listed replacement breaker for them any more.

    Suspect, not necessarily dangerous.
    You notified them of your concern. You did your job.

    If nothing else, it's old technology.

    I can't see everything in your pic, but I see a backfed breaker that doesn't appear to be secured.
    Is this service equipment?

    Gunnar,

    The black wire at the top left side of panel?? I agree with you that some unprotected circuit is coming off the bus.

    Ummm... there's a lot of black wires.

    Probably not. I was referring to the topmost 240 volt breaker. I assumed that is the main disconnect. It looks like a 100 amp breaker and the neutrals/equipment grounds are connected together at the bottom of the panel. If the panel is not service equipment, then the neutrals/equipment grounds are incorrect. Is it service equipment?

    If it is the main disconnect, then it looks to be backfed (fed from the conductors to the buss bar rather than from the buss bar to the conductors). Backfed breakers should be secured to the panel (I don't know when that became a requirement).

    Are you are referring to the smaller gauge wire that heads from the top/left toward the main lug at the top of the panel? If that is connected to the main lug, then I cannot imagine an electrical contractor "certifying" this panel.

    I take things differently at times, such as an electrician calling an FPE panel "perfect" means to me that it is a "perfect" FPE panel, and we all know that FPE panels have issues, so a "perfect" FPE panels would "perfectly represent all of the issues of FPE panels".

    Likewise, we all know that Zinsco panels are issues, thus a perfect Zinsco panel would perfectly represent all the Zinsco panel issues.

    Now, if the electrician were to document that "all" appropriate tests were done on the breakers, the buss bars, and all other aspects of the panel, and that all those tests passed, then, sure, go ahead and put forth the meaning that the panel 'has no issues as it was fully tested and passed all tests'.

    Otherwise, that piece of paper from the electrician is not worth anything, unless that electrician also provided a letter from his insurance company stating that the insurance company will fully cover any and all losses and incidents arising from or related to that Zinsco panel ... and then it is not the electricians letter which means anything, it is the insurance company's letter which means something.

    Thus my response to my client would be to have the seller provide a letter from the electrician's insurance company covering all losses and incidents arising from or related to that Zinsco panel.

    I suspect that seller will never get such a letter, because I suspect that the electrician could never get such a letter from his insurance company, at least not without some additional giant premium being paid for that insurance coverage.

    Otherwise ... that letter is not even worth what toilet paper is ... that letter is too stiff for wiping ...

    Some electricians are idiots, even the licensed ones.

    As much as I hate Zinsco/Sylvania panels, the plug-in panels are problematic, the bolt-on panelboards are not really a problem, other then paying outrageous prices for used breakers when needing one for replacement or adding a circuit, $140.00 for a 20A 2-pole breaker that was much older then the circa 1976 panel it went into.


    The Zinsco residential panels were just a really bad design.

    Zinsco are still used even after a Home Inspector's " visual inspection report" the condition in their written report. Some building and safety city inspectors "grandfather them in" after an State Licensed Electrician rewire the branch wiring and leave the Zinsco Service Panel in place.

    Even in this case I call it out as "needing to be evaluated by a State Licensed Electrician" if a State Licensed electrician come on record and document the "Zinsco Electrical Panel" as "perfect" that is the end of the matter as to my responsibility to my client, the national electrical code have changed many times since the Zinsco electrical Panel was manufactured. My report is based on the condition of the property "on the day of the inspection".

    I have had electrician state that they are fine, I have some Realtors her locally that say they have an electrician that will "Certify" them as okay. I still have the conversation with my client why they are not.

    The issue is there is no recall or industry warning other than we HI's and a few insurance companies state. Most electricians I know who worth their weight in salt agree that they should go bye -bye.

    I have plenty physical example of issues with Zinsco's in my possession (pitted bus bars, melted breakers etc)

    FYI- Some insurance companies will have an issue with them. I have a client that has an apartment complex that Zinsco's were installed. The insurance company is charging him 20K extra a year in insurance rate for having them present. He was a little peeved because the inspector that did that inspection did not mention anything about them.

    That's how FPE panels finally became such a no-no that agents basically had no choice but to acknowledge the issues ... the insurance companies began saying that they would not insure the houses ... and no insurance means no sale ... and agents don't like "no sale".

    It is unfortunate that the "Sale" becomes the driving factor versus the issue of these being poorly designed and cheap.

    It also hard to get the consumers/public to understand that some of these older panels may have reached a useful life and it is time to replace them.

    I've been calling out Zinscos for years as a safety concern and recommending replacement. Only had pushback once from an 'electrician', who said it was fine, but would not offer that up in writing.
    Here's one from a package unit disco last July.
    I include this link in my report. http://www.ismypanelsafe.com/zinsco.aspx

    I suspect that the only "good" Zinsco panel is one which is still in its original unopened box ...

    Yes-sirree ... it is "listed" and "ready for use" (just don't use it).

    Well ... I'll be doggone ... I never thought someone would have one ... wait a minute now - I said "unopened" ...

    But that's 'close enough' to round the bases and make the score.

    My client wanted me to look at this and get an opinion, I told him it looks great and that is should always remain in the box We actually had a good laugh about it.

    Absolutely the best place for it ... in that box.

    I'll make a slight correction to the above as I have seen "split bus" Zinsco panels before ... that panel is a "manufactured" split bus Zinsco panel ... I have seen 'split bus' Zinsco panels which 'became split bus' because the bus bars MELTED COMPLETELY IN TWO due to arcing from the breakers ... so someone added a breaker to the now-split-off-bus and jumpered from one breaker in the top section to a breaker they put on the 'now-bottom-section' ... and the agent couldn't comprehend why I was writing it up.

    You could have had a pallet of Challenger branded FPE Stab Lok loadcenters at a local auction a few years ago, would have loved to see the buyers face when they found out how much breakers were going to cost.
