What Breakers Are Compatible with Zinsco? Best Answer

By James N. Miller

Are there any Zinsco breakers that will work with the panel you still have this company produced? Since it’s quite likely you won’t find Zinsco breakers with updated compatibility chart any longer, the best response is to avoid looking for one simply. Furthermore, a specific Zinsco circuit breaker is unlikely to still exist for your panel.

Due to its panels’ somewhat subpar past performance, this brand is no longer regarded as secure by local codes. If you keep using it, you practically put your home in danger of electrical and fire threats because it frequently fails to trip. I advise you to swap out the new panel or, if money is tight, swap it out for a brand-new UL-certified breaker compatible with the panel.

What Zinsco Panels

Previously, Zinsco In some regions of the country, electrical panels were frequently installed in residences. With time, electricians and home inspectors have learned that some Zinsco panels frequently experience improper operation, putting homes and their occupants at risk of fire and electrical shock. These panels may function properly for years, but when homes’ energy needs rise, they may overheat, and some of the material may melt.

An extraordinary quantity of electricity from the external electrical supply rushes into a home’s panel and circuits in this scenario if a breaker burns to the bus bar of the panel and can no longer appropriately trip in the event of an over-current or short circuit. After that, it cannot be manually turned off or halted. Electricity will keep burning until the fuel runs out or the conductors melt. A house and its residents could suffer severe injury if the panel overheats and catches fire.

For years, Zinsco panels can appear to be in perfect working order. But experts caution that if and when these panels malfunction, they could cause a wide range of issues and even dangers. In fact, according to one expert, up to 25% of Zinsco circuit breakers may not trip in response to an overcurrent or short circuit, thus posing a danger.

It is impossible to see issues with some Zinsco panels with the naked eye. The Zinsco panels’ cover can still be removed, and everything may appear in perfect working order. Electricians discover the bus bar’s breakers cannot be removed after dissecting it. As a result of the breakers melting, they have welded together. A breaker in that situation wouldn’t be able to trip, and the amount of electricity entering the house might be harmful. Possibly, a fire could result from this.

To check if your breakers have melted, kindly refrain from attempting to remove them from the panel. Only electricians with licenses should. Zinsco panels risk electrical shock because they may still carry electricity even when they appear off.

Are Zinsco Electrical Panels Dangerous?

If your Zinsco panel has a problem, it might not be obvious immediately. They might appear to function properly without any problems for a long time. Even if you attempt to take off the lid, nothing will change.

Electricians and industry professionals believe Zinsco electrical panels to be harmful. About 25% of the examined panels failed due to Zinsco circuit breakers that melted and fused to the aluminum bus bar.

The Risks Associated With Zinsco Panels and Circuit Breakers

Zinsco replacement breakers might once have been perfectly viable (albeit perhaps not safe), but those days are long gone. Mind you, at that time Zinsco was still a small manufacturer; it would have been in the 1960s or early 1970s.

These breakers frequently fail to trip, whether they are Zinsco breakers with a capacity of 125 amps or others with a lower or greater capacity. Consider situations where two-pole breakers fail, but only one of the poles fails and remains engaged while the other fails.

Even after running at levels between 135% and 200% of its present capacity for hours, others don’t trip! This is important information because current codes demand that breakers be able to handle those loads. In the US, they are even tested religiously for it.

Although you can’t remember when it tripped the electrical system, does your Zinsco breaker have parts that have melted off? No other indicator of subpar breakers exists. Aside from that, it wouldn’t hurt to make sure the breakers are truly properly seated because there is another problem with the breakers linked with this brand that is frequently encountered.

Do you now see why looking for Zinsco breaker replacements is not sage? It’s a good thing that Zinsco-produced breakers are no longer offered on the market now for the benefit of everyone. Naturally, that doesn’t stop some unlicensed shops from selling “alternatives.”

By Edwin 

Avoid being duped by fraudulent marketers who offer “working replacements.”

Although Zinsco panels can be used to replace Sylvania breakers and GTE Sylvania circuit breakers, you should be wary of retailers that offer ostensibly superior alternatives under these brand names. They are probably phony.

In this extremely helpful post, Inspectapedia has already refuted the assertions made by these merchants. Given the remote possibility that you still run into ersatz circuit breakers, I advise you to review it. That also helps to confirm the details I also mentioned here.

I Will Only Recommend This Breaker Brand for Zinsco Panels

Choose the panels made by Connecticut Electric with the utmost caution if you have no alternative and must leave the old panel in place. Why am I not hesitate to endorse them? Because they are the exclusive owners of the intellectual property for the original Zinsco breaker design and have taken extra precautions to guarantee their safety and compliance with current UL requirements.

It says a lot about their general credibility that they are still unafraid to advertise Zinsco replacement breakers on their primary website. If Zinsco had lasted, Connecticut Electric would be the most modern equivalent; therefore, if you want breakers that work with your Zinsco panel the best, stick with them.

The electrical panel should be entirely replaced as the best line of action

Can you claim that your home is completely secure while you’re still utilizing an antiquated panel? Just consider the potential damage after a fire and the associated repair expenditures. If you get rid of the panel, you’ll only save more money in the long term.

Even better, if the homeowner has the appropriate electrical knowledge, replacing a Zinsco breaker may be done without a professional electrician’s assistance. I suggest watching this video first if you want to do it yourself and need to get comfortable with the general process.
