Zinsco panel and breakers

The wife and I found a very cosy looking home in a remote setting in northern virginia that we plan to make our own little getaway paradies. The previous owner didn't have the exact information but it was build somewhere in the 70s, which is where my problem comes in. The panel and breakers are all Zinsco, you know, the company infamous for unsafe equipment. It's been standing for over 5 decades and it's all good, but I still think I want to replace everything. Am I overthinking this, or should I upgrade? If the upgrade is your answer, which brand should I aim for? The apartment we're living in has Siemens, so it that a good option or are there better ones?

It's great that you spotting the Zinsco panel. Even if it's been okay for decades, their reputation is pretty rough. Upgrading is probably a wise investment for your getaway paradise
 
Definitely upgrade it. Zinsco panels are known for being a fire hazard, even if they've been standing for decades without issue, also consider Square D or Eaton along with Siemens, hey are both are reputable, reliable brands and would give you peace of mind.

Nice, congratulations on that piece of paradise! I would echo what they said and go for an upgrade! Siemens seems like a good option, especially that you're already familiar with it! If you haven't made a choice yet, it's best to consult a licensed electrician who can assess your specific needs!
 
Hello Multifunctionalhusband,
Your new home sounds great!

As the others said, it would be wise to eliminate the Zinsco. I worked industrial & distribution and encountered many Zinsco serving office spaces, mostly Q-Series. Lots and lots of problems arose- even back when they were new. I saw no fires that left the enclosures, but the fires burned all wiring inside the enclosures.

Also note that purchasing a replacement circuit breaker might be difficult. They are becoming harder & harder to find. (Perhaps that is a good thing. You can sell the bus bars and breakers on eBay or Bonanza for some quick money!)


Here's A Silver Lining-
Can you negotiate a discount on the home price due to the pending service work? Note that some insurance companies will not insure when Zinsco (or FPE Stab-lok) are in the building. That's a bargaining point for you.



Brand?
My preferred brand is Eaton Cutler Hammer. Bolt-on is ideal, but snap-in are also excellent. As mentioned by others above, Square D is great (QO being superior to Homeline). Siemens is also excellent.

Important-
Once you do replace the load center, contact your insurance company. I did a few "friends and family" freebies where I replaced FPE or Zinsco load centers. The home owners received a lower home insurance premium due to reduced fire hazard.

Very Important-
And Absolutely, Positively, Certainly make sure the electrician is licensed, insured and takes out permits. When the job is complete, ensure that the AHJ inspects and issues a Green Tag. (If this will be a DIY job, be sure to get a Homeowner's permit and have your work inspected.)

A Good Plan-
If I may step beyond your inquiry, should you replace the load center consider what the current service ampere rating is. You may wish to upgrade for the future. Perhaps you will someday want, for example, an electric vehicle or something in the fun stuff category (central air, hot tub...)

Again, congratulations on finding a great home! I hope you guys love it!

iI you're on the fence then what PGB1 says about Insurance Companies is salient. Whether you want to or not it's only a matter of time before they request it be replaced so do it on your schedule, not theirs.
