Sylvania Electrical Panels & Breakers
Electrical panels that do not use the Zinsco™ breaker design

POST a QUESTION or COMMENT about the identification of Zinsco, Sylvania-Zinsco, and Kearney Electrical Panels - Zinsco-look alike Electrical Panels and Circuit Breakers

Sylvania, non-Zinsco circuit breaker & electrical panel identification guide:

Here we provide text, labels, and equipment photographs used to help identify Sylvania electrical panels and circuit breakers. These electrical panels do not use the Zinsco or GTE-Sylvania-Zinsco electrical panel bus and breaker design.

Sylvania Electrical Panels that are NOT a Zinsco design

Note: photo shown above of a recent GTE Sylvania Zinsco circuit breaker burn up was provided courtesy of Jeff Weissman who reports its occurrence in a GTE-Sylvania electrical panel.

This circuit breaker may have been installed in a GTE-Sylvania electrical panel that did not use the Zinsco-design circuit breakers and/or may be of a different brand or manufacture.

Reader Question: is this Sylvania panel a GTE-Zinsco model?

Enclosed [above] is a pic of my Electrical Box but does not show that it’s a GTE Zinsco which are having to be replaced.

Can you tell me by the pictures [shown here] if mine is a ZINSCO™ electrical box that is unsafe? - anonymous by private email 2018/05/02

Reply: probably not, here's how to know for certain

Could you please send me a photo of the electrical box entirely from its outside front, and a photo showing a close up of the circuit breakers themselves. Don't remove the cover that is don't expose the panel interior because you could get shocked.

BTW the panel label identifies this as a Sylvania SB12(20-24C) 125A electrical panel. The list of permitted circuit breakers given on the limited part of the label that we have does not include the Zinsco -Sylvania circuit breaker line.

I want to see the color and appearance of the circuit breakers.

... [after photos were received]

At IDENTIFY GTE SYLVANIA-ZINSCO PANELS we show the

GTE Sylvania Zinsco panel labels:

Typical GTE-Sylvania-Zinsco label that includes the words GTE SYLVANIA and ZINSCO
GTE Sylvania Zinsco breaker toggle colors:

Black , aqua, red, and blue circuit breaker toggle switches.

Your label does not include those terms and all of your circuit breakers are black. Your photos were not sharp enough for us to read the breaker labeling or text.

GTE Sylvania Zinsco panel bus and breaker connections:

Beyond those identification keys, to absolutely rule out the presence of this circuit breaker in your panel, your electrician would need to

Open the electrical panel, remove the panel face, pull one representative circuit breaker, and compare the side of that breaker as well as the electrical panel bus-bars to which the breaker connects to those in this photo.

Watch out: do NOT try to open up your panel nor to remove circuit breakers yourself. There is live voltage in the panel interior - you could be shocked or killed. Never insert any tool nor your fingers into the interior of an electrical panel. Electrical panel interior access should be by a licensed and trained electrician.

What a True Zinsco-Sylvania Circuit Breaker & Panel Bus Looks Like

Below: The photo shows a classic Zinsco-Sylvania circuit breaker design.

Or without pulling a breaker, see this view in the electrical panel:

Below: The photo shows another classic Zinsco-Sylvania circuit breaker design.

Or see circuit breaker labels matching those in the article above on this page.

IF the bus and breaker in your panel match these - a vertical or thin on-edge strip bus and those deep slot connectors in the circuit breaker,

THEN you have the poor-performing breakers that we describe.

IF NOT (which I think is the case for your panel) you have a different panel design for which we don't have the same failure rate data nor reports.

Examples of Sylvania Electrical Panels, Bus, Breakers that are Not the Zinsco-Design

On 2023-05-03 by InspectApedia Editor - Connecticut Electric replacement breakers performed the same as UBI circuit breakers

@Frank Smalarz,

Connecticut Electric replacement breakers performed the same - as you'll read in Aronstein's test report in this article series. Sorry, I should have made that clear.

However I agree with you that copper bus bars would be a substantial performance improvement. IF the bars were solid copper. I think you'll read that Aronstein found that insertion of Zinsco-style breakers onto a copper PLATED bus bar scratches right through the plating to expose the aluminum base material and to invite arcing and overheating - the performance wasn't what one would have hoped.

I appreciate the wish to avoid a panel replacement and you can be sure that if we had independent, unbiased information supporting replacement breakers and parts we'd sure be happy to share that information.

@InspectApedia Editor , Hello, the response I received was relative to UBI circuit breakers tested in 2017. I'm asking about Connecticut Electric breakers, but more importantly their replacement copper buss bars.

From what I've read about the Zinsco failures is that it's primarily attributed to the aluminum buss bars which are softer than copper and result in scratching/gouging and resulting poor contact.

On 2023-05-01 by InspectApedia Editor - high failure rates for FPE and Zinsco replacement breakers, too

@Frank Smalarz,

I would replace the panel.

The "replacement breakers" that you ask about were tested independently (see Aronstein's reports) and had about the same failure rate as the original equipment. That's proven the case for several brands with high failure rates such as FPE and Zinsco. Example: see

ZINSCO CIRCUIT BREAKER TEST REPORT - testing on UBI replacement circuit breakers sold for Zinsco electrical panels

and see

UBI FPE CIRCUIT BREAKER TEST RESULTS - also not recommended, fail at similar rate as FPE original equipment

On 2023-05-01 by Frank Smalarz

@InspectApedia Editor , Thanks for your response.
Are the Connecticut Electric breakers and buss bars an adequate replacement for the Zinsco hardware? Is the source of the problem the aluminum buss bars of Zinsco or do the breaker contacts have some particular design problem?

Are the Cutler Hammer retrofit kits a safe alternative?

Do you know what the difference is between the Sylvania MTMB10 panels and the SMB/SB panels that seem to predominate as being a problem?

On 2023-04-28 by InspectApedia Editor - multicolored toggle switches look like the troubled design

@Frank Smalarz,

Most-likely, from their multicolored toggle switches, we can say yeah those look like the troubled design.

For an absolutely-certain check it's easy enough to have an electrician or experienced contractor open the panel enough to look at the circuit breaker side and bus connection design: the Zinsco design is unique and unmistakable - with those deep slots in the breaker body - here's an example photo from the article above

Watch out: do NOT try to open up your panel or remove circuit breakers yourself. There is live voltage in the panel interior - you could be shocked or killed.

On 2023-03-05 by InspectApedia Editor - Sylvania model 390-205-09 missing part of panel door

@ray moshiri,

In addition to the death by electrocution hazard of leaving the cover off of an electric meter box as you show and comment, there are more subtle hazards that come from leaving the electrical wiring exposed to the weather, to water, to short circuiting.

For an old Sylvania electric meter box and panel combination such as shown in your photo, I think. you'll have trouble finding an original equipment manufacturer OEM part that fits exactly.

Start by asking your local electrical inspector if she or he will approve and consider safe a custom-fabricated cover made by a local metal working shop to whom your electrician gives measurements.

But the bottom line is that this is an obsolete meter and panel that in fact should in my OPINION be replaced with a new electric meter base and most-likely a completely separate main switch and electrical panel, the latter, perhaps, indoors.

On 2023-03-05 by ray moshiri

I have a Sylvania model 390-205-09 which is a main circuit breaker but the door panel adjacent to it where the meter by DWP was installed, the bottom cover is missing and it is 7.5 inches in length to 17.5 inches. height. Where do I buy that door panel because the wires are exposed and dangerous if touched accidentally?

On 2022-12-12 by InspectApedia (Editor) - Sylvania SLB20 electrical panel cause for concern?

On zooming in for a closer look the photo is a bit blurry, but I don't see the characteristic deep slots that appear in the sides of Zinsco circuit breakers.

Compare the photo above - excerpted from this article.

I have a client with a Sylvania SLB20 electrical panel. I opened the panel and I don't see any burn marks near the breakers or wires. I don't see any Zinsco labels on the panel or breakers. Wondering if this panel or breakers are the ones that could be fire hazard, would like your opinion. Thanks.

On 2022-07-06 by InspectApedia-911 (mod) - Zinsco circuit breakers should be replaced

@Jim,

Thank you for the good photos. Yes that's the Zinsco circuit breaker design that is unsafe. I would replace the entire panel.
A report that the breakers are good and tight has no meaning with respect to the safety hazard of us circuit breaker that doesn't trip or catches fire.

You could leave the panel and agree to make an allowance to a buyer however that may slow your sale process as some buyers will find that their mortgage company won't issue a mortgage or their home insurance company won't issue a fire policy until the panel is replaced.

On 2022-07-06 by Jim

I'm sending an image of the side of a breaker that goes in my electrical panel. Is it of the Zinsco design? Like I mentioned before the technician said all breakers were good and tight and that everything was good. We're trying to sell our house and hope to not have to upgrade the electrical panel

...

On 2022-07-06 by InspectApedia-911 (mod)

@Jim,

No, definitely not. Only panels that use the zinsco circuit breaker design are the ones that need to be replaced.

That's easy to identify by simply looking at the panel bus or looking at the side of one of the circuit breakers.

On 2022-07-05 by Jim

Do all GTE Sylvania Zinsco Electrical Panels need to be replaced? Ours is 44 years old and we've never had a problem with it. Had a licensed electrician check it out. The technicians said it was in good shape. All breakers are tight and none felt hot and all wires are in good shape

On 2022-04-28 by Inspectapedia Com Moderator - Sylvania 200AMP meter socket

@Anonymous,

Curious that part of the electric panel label was torn away, so the model number isn't there.

You wouldn't expect to be able to connect more than two individual hundred amp breakers, each controlling one leg of the circuit and giving a total of available amperage of 200.

On 2022-04-27 by Inspectapedia Com Moderator

@Mats,

I don't know for a fact all of my assumption its 100-amp just as you described. If you can find a sticker that has a product number or model number it might be possible to research the panel further.

Can you tell me the age and location of the building?

On 2022-04-27 by Mats

I have a Sylvania 200AMP continuous meter socket. From the Meter the 200AMP will go to a Generac ATS (Automatic Transfer Switch) and then comes back into to this panel where it is split into 2X100A to drive the 2 main panels in the house.

I am now planning to add Solar it will connect via an Enphase IQ System Controller 2 that will replace the spot of the ATS.

Does anyone know the busbar rating for this bus bar (it only handles the split of the 200A into 2x100A as you can see from the photo.

Question: we were told that ALL Sylvania Electrical Panels are Unsafe & Must Be Replaced

We have a Sylvania electrical panel in a home. And we were told all Sylvania were unsafe. Can you please tell us if ours is safe or should it be replaced? - Anonymous by private email 2022/04/28

Moderator reply: Really?

Thanks for the question, Anon.

No one with an ounce of experience or sense would nor could pronounce your electrical panel "safe" based simply on seeing photos of its exterior and its label. Not if by "safe" we mean - "are there unsafe or questionable conditions in the electrical panel?"

[Click to enlarge any image]

That requires removing the panel cover to expose the breakers, wiring, wire connections where an experienced inspector looks for a laundry-list of problems like leaks, corrosion, overheating, improper wiring, wrong wire size, wrong breaker size, mechanical damage, and other snafus.

I realize you were probably not thinking of how an old inspector might approach a panel and you just are asking "are all Sylvania Electrical Panels Unsafe" and "do all Sylvania electrical panels need to be replaced?" - based only on the brand name itself - Sylvania.

My answer to that is no.

Indeed there was a line of Sylvania-Zinsco electrical panels that used a particular bus design that accepted Zinsco circuit breakers. The "bus" is the metal bar to which the circuit breakers connect and through which the breakers receive electrical power. Those panels are unsafe and should be replaced.

Those unsafe Sylvania-Zinsco electrical panels are described, illustrated and identified in a series of articles beginning at

ZINSCO SYLVANIA ELECTRICAL PANELS - home

It is trivially easy for a professional home inspector or licensed electrician to open the electrical panel, remove the cover, and examine the circuit breakers to identify that Zinsco design.

But there were plenty of other models of Sylvania electrical equipment including electrical panels that had not one iota of "Zinsco" design or components in their make-up.

From external appearance and panel label information yours is not a Sylvania-Zinsco panel, but your electrician should confirm that (as I just have a pair of tiny photos) by checking the panel interior details as I describe herein. (OPM? Guilty! - see below.)

Sylvania Brand Electrical Panel Label Details (Non-Zinsco)

Sylvania Electrical Panel Catalog Nos. SB20(20-40)C (Indoor) Mod. 1 / SB20(20-40)CG (Indoor Mod.1.) 200A, 120/240VAC

Use GTE Sylvania Circuit Breakers Type A, C and HAGF. Fodr Special duty use Bryant TType BRWH (Water Heater) , Type BRSN (Switched Neutral) and for switching duty, Bryant Type BR marked SWD.

None of the circuit breakers listed on the panel label is a ZInsco-type circuit breaker.

An examination of the electrical panel bus design and breakers quickly identifies the presence of absence of Zinsco-type breakers.

Watch out: Now while one of those "other Non-Zinsco Sylvania" panels might be unsafe or need replacement for other reasons, such as the potpourri of unsafe conditions I listed earlier, and while some of those too may need replacement, that's independent of the Zinsco breaker hazard.

You said "... we were told all Sylvania [Electrical Panels] were unsafe. "

You don't identify just who said that, nor that person's expertise. I would be very grateful if you'd ask that person why they gave you that advice, and if they have facts, data, articles, studies, or other expert sources that support the claim that "all Sylvania Electrical Panels are unsafe and need to be replaced" I would be very grateful to receive that information.

I suspect we're seeing a case of the OPM problem: somebody is going to spend a lot of YOUR MONEY to make THEMSELVES "SAFE" - safe, that is, from a possible future complaint by you that they didn't warn you about something.

See OTHER PEOPLE's MONEY - why some contractors or consultants or other spend your money to protect themselves - from you.

Question: examine the electrical panel interior bus and breaker design for a quick and easy identification of "Zinsco" type

Richard ONeal
@embarqmail.com

Is the Sylvania electrical panel model SL12(12-24)C one of the panels considered a fire hazard because of the GTE or Zinsco design

Moderator reply:

I"m not sure, Richard; can you attach a photo of the panel's circuit breakers?

Also if your electrician or inspector opens the panel to show its bus design we can say for sure if it's a Zinsco- the circuit breaker-to-bus bar connectors and the bus bars themselves are very distinctive - on-edge metal bars.

Watch out: if you're not trained in safe electrical procedures don't try removing the panel cover - you could be shocked or killed.

Jack,

I did not find an interlock for your Sylvania Electric model.

However as I suggested, an electrician ought to be able to install a sub-panel off this one that can handle other brands and provide an appropriate transfer switch - an "either-or" type safety switch.

On 2020-09-21 by jack

I have a panel similar to that described by sharon in this section of the site. It is definitely sylvania, uses QBH circuit breakers. Is there an interlock kit for this? I haven't found one --again similar to Sharon's situation.

we recently bought a home with a Sylvania panel. We're in Ontario Canada, house was built sometime between very late 70's and very early 80's (no firm documentation).

Its a 200amp panel, we are trying to find an interlock to install a generator plug outside for emergency power.

Currently there is a double breaker 60amp on the bottom left, we plan on getting that moved to a "pony panel" as its the power that goes out to the barn electrical panel, and that would free up the space for a double breaker 30amp for the generator plug.

But we still need to find an interlock for the panel. we tried search Sylvania, and Cutler, and Westinghouse, but none of the panels look anything like ours.

Pretty confident its not one of the Zinsco panels, so not looking to replace the panel. Any ideas one what is the proper interlock to install on the panel?

On 2019-12-10 by (mod) -

Anthony,

Your electrical panel is a Sylvania Electrical panel model, Catalog No. SB15(20-30)C (Indoor) Mod.1 150A Max.

So we know that the panel was rated to provide a maximum of 150 Amp 240VAC electrical service (though your service ampacity could be less). The panel label also gives some restrictions on number and types of circuit breakers that could be installed.

Beyond that, you asked "... tell me about this breaker panel..." - if you have a specific question we could perhaps be more helpful. Else I can but guess that you're asking if this is one of the problematic Zinsco-Sylvania panel models.

This panel is no longer manufactured new, though we do see some vendors selling new old stock.

[Click to enlarge any image].

Most-likely this is not one of the problem Zinsco-Sylvania panels, but

1. It would be helpful if you'd also post a photo of the circuit breakers in your panel. Then we can look for the characteristic red or blue toggle switched breakers that are one of the indicators of Zinsco-Sylvania versions (that are unsafe).

2. It would be helpful to know the city where the building sporting this electrical panel is located and

3. to know the age of the building or home (and whether or not this is probably the original electrical pane).

Can anyone tell me about this breaker panel? [Shown above]

I can't seem to find it online.

On 2019-10-16 by (mod) - which way is the "OFF" position on this Sylvania electrical panel?

Elder

Switches in positions 9-10 that is a 240V double pole breaker looks to be in the OFF position. Try pushing it towards the panel center strip.

Sometimes if a breaker has tripped it needs to be switched fully to OFF before it can be re-set to ON.

So if you're having trouble switch the breaker fully to OFF (away from the center of this Sylvania electrical panel) then switch the toggle handle towards the panel center or ON as shown in our edit of your photo - below,.

It is certainly NOT a stupid question - lots of people run into confusion about which is the "ON" Position for circuit breakers as I'll detail here:

Switches in positions 9-10 that is a 240V double pole breaker looks to be in the OFF position. Try pushing it towards the panel center strip.

Thank you for asking.

On 2019-10-16 by Elderberry

This is a stupid question I know, but yesterday I had an extension cord running from my garage outside to weld.

I lost power and noticed that electric outlet in the garage no longer worked, thinking that I tripped a circuit I went into the basement where the main circuit breaker is and flipped all the switches on and off again.

Then I realised the source of my problem was a blown fuse in the garage.

I changed that and the electric outlet in the garage started working again.

Now my water heater and drier doesn't seem to be working.

My question is are all the switches in the circuit box in the correct position? I can't tell.

When was it determined that the Sylvania-Zinco electric panel were unsafe? I know they were installed in places in the 1980"s

On 2019-02-06 by (mod) -

Alberto,

I agree that the breakers in your photo do not look like and almost certainly are NOT Zinsco (or Zinsco-Sylvania) circuit breakers. They don't have the characteristic deep narrow slot that you see in other Zinsco photos including one just below your own posting.

The identification of the problematic Zinsco breaker design can be difficult if the inspector can't see inside the panel (inspection standards generally expect the inspector to remove the cover and inspect the interior as long as he feels safe doing so) - since Zinsco design breakers were installed in panels bearing the names

Zinsco

Zinsco-Sylvania

GTE-Sylvania

That's why one needs to look at more-technical details.

I'd also like to see

- a photo of the whole panel

- photos of the panel labels or markings

- to know the age of the home

I don't want to generate a fight with your home inspector but it appears to me the inspector is mistaken.

Perhaps you could ask the inspector to provide any documentation that asserts that Sylvania Electric Panels that are NOT Zinsco design are an unusual hazard that justifies their replacement.

Take care: Neither you nor I want to be roped into providing any guarantee, warranty, safety promises about your home - me in particular as I don't know a thing about your home - since in the future, heaven forbid, when ANYTHING goes wrong that could be the subject of a future dispute.

Finally, a home inspector has not one iota of authority to *require* a home seller to do anything, including replacement of electrical panels.
However a home inspector is obligated to point out life safety hazards (as well as other property conditions) that she or he observed - something that would protect everyone involved.

Nevertheless I will much appreciate any information your buyer's home inspector can provide that helps us understand the basis for her or his recommendation that the panel needs replacement.

You're welcome to print this page along with our conversation to share with the other parties involved.

Respectfully Daniel Friedman, Editor.
