If your NJ home was built or significantly remodeled between roughly 1950 and 1990, there is a real chance the electrical panel inside is one of five brands that the electrical industry, the Consumer Product Safety Commission, and most major insurance carriers now treat as defective. They are still legal to leave in place under grandfather clauses — but they are increasingly uninsurable, and every one of them has a documented mechanism for failing in a way that can start a house fire.
This is the complete 2026 reference list. We pull or replace one of these panels somewhere in Hudson, Essex, or Bergen County almost every week. If yours is on this page, you should not panic — but you should plan to replace it.
The Five Defective Panel Brands at a Glance
| Brand | Years installed | Failure mode | NJ replacement cost (2026) |
|---|---|---|---|
| Federal Pacific (FPE Stab-Lok) | 1950–1990 | Breakers fail to trip on overload | $3,500–$5,500 |
| Zinsco | 1950s–1970s | Aluminum bus bar corrosion; breakers fuse to bus | $3,500–$5,500 |
| Sylvania-Zinsco / GTE-Sylvania | 1970s–1980s | Same Zinsco bus / breaker design under a different label | $3,500–$5,500 |
| Pushmatic / ITE Pushmatic / Bulldog Pushmatic | 1950s–1970s | Breakers stick in the closed position; no easy replacement parts | $3,200–$5,200 |
| Bulldog Electric | 1940s–1970s | Obsolete bus design; arcing and overheating; no UL-listed modern breakers fit | $3,200–$5,200 |
All five ranges assume a like-for-like 100A or 150A service swap on a single-family NJ home, full UCC permit, municipal inspection, and PSE&G or JCPL coordination. A 200A service upgrade typically adds $400–$1,400. See our 2026 NJ Panel Upgrade Cost Guide for the full breakdown of what drives the price.
1. Federal Pacific Electric (FPE) — Stab-Lok
The most-installed defective panel in New Jersey. Federal Pacific manufactured Stab-Lok panels from the early 1950s through the late 1980s, and Hudson County housing stock from that era is full of them — Jersey City brownstones, Bayonne 2-families, Newark single-families, you name it.
How to identify a Federal Pacific panel
- The panel door or directory label reads "Federal Pacific Electric" or "Federal Pioneer"
- The breakers are stamped "Stab-Lok" and have a thin, narrow profile with a distinctive red strip across the toggle
- The FPE logo (an "FP" with a small lightning bolt) is often visible inside the deadfront
- The panel is usually gray or beige with a brown or red trim
Why it's dangerous
Independent testing — most notably the work of Dr. Jesse Aronstein in 2002 — documented that Stab-Lok double-pole breakers fail to trip under standard overload conditions in 51% to 65% of tested units. A breaker that does not trip cannot stop a circuit from overheating. The CPSC investigated FPE multiple times and the company was found to have falsified UL listings. The breakers were never legitimately UL-certified to the standard the labels claimed.

2. Zinsco
Zinsco panels were installed primarily through the 1960s and 1970s. The brand was eventually absorbed into GTE-Sylvania, which is why you will sometimes see the same physical panel labeled as Zinsco, Sylvania, or Sylvania-Zinsco depending on the year.
How to identify a Zinsco panel
- The panel directory reads "Zinsco" or "Magnetrip"
- Breakers are multicolored — typically tan, brown, blue, or green — with a distinctive notched shape
- The bus bar visible behind the breakers is aluminum and often shows visible corrosion, dark spots, or a melted appearance
- The panel cover is often a flat brown or tan steel face plate
Why it's dangerous
Two interacting failure modes. The aluminum bus bars corrode where breakers clip onto them, creating high-resistance connections that overheat under load. And the breakers themselves are known to physically fuse to the bus over time — meaning a tripped breaker may stay energized, and a homeowner trying to reset a tripped breaker may instead be holding contacts together that should be open. Several documented NJ house fires have been traced to Zinsco panel failures.
For identification and replacement details, see Zinsco Panels: The Other Dangerous NJ Panel and the 2026 NJ Zinsco Replacement Cost Guide.
3. Sylvania-Zinsco / GTE-Sylvania
This is the same physical Zinsco panel, sold under a different label after GTE-Sylvania bought the brand in the 1970s. NJ homeowners often see it on permits or inspection reports labeled simply as "Sylvania" and assume it is unrelated to the Zinsco safety concerns. It is not — it is the same panel.
How to identify a Sylvania-Zinsco panel
- The panel directory reads "Sylvania", "GTE-Sylvania", or "Sylvania-Zinsco"
- The breakers are the same multicolored notched shape as Zinsco — tan, brown, blue, green
- The interior bus bar is aluminum and shows the same corrosion patterns as Zinsco
- Often labeled "Magnetrip" on the breaker face
Why it's dangerous
Same failure modes as Zinsco — aluminum bus corrosion at the breaker contact points, and breakers that fuse closed over time. NJ insurance carriers treat Sylvania-Zinsco identically to Zinsco. If your inspector reports a "Sylvania" panel, ask specifically whether it is a Sylvania-Zinsco from the 1970s–80s or a modern Sylvania-branded panel from later — they are not the same product.
4. Pushmatic / ITE Pushmatic / Bulldog Pushmatic
Pushmatic panels were installed widely from the 1950s through the early 1970s and are extremely common in older Newark, East Orange, Irvington, and Bayonne housing stock. They were originally manufactured by Bulldog Electric, then sold under the ITE Pushmatic name, and are sometimes labeled simply "Pushmatic." All variants share the same problems.
How to identify a Pushmatic panel
- The panel directory reads "Pushmatic", "ITE Pushmatic", or "Bulldog Pushmatic"
- Instead of toggle breakers, you push a square or rectangular button to switch each circuit on or off
- A small red indicator window on each breaker shows whether the breaker is on or tripped
- The panel face is often light gray or beige with the breaker buttons in a vertical column
Why it's dangerous
Pushmatic breakers age poorly. The internal mechanism that should release on overload becomes sticky over decades, and in many tested units the breaker fails to trip when it should. Even when the breaker does trip, the indicator window can show "on" when the circuit is actually broken, or "off" when the circuit is still energized. Compounding the problem, no major manufacturer makes new Pushmatic breakers — your only options are NOS (new old stock) or used breakers of unknown age, neither of which is acceptable in a modern panel.
If a Pushmatic breaker trips and is hard to reset, do not force it. Call a licensed NJ electrician immediately and plan for a panel replacement.
5. Bulldog Electric
Bulldog Electric panels predate the Pushmatic era and were installed in NJ homes from the 1940s through the late 1960s. Some Bulldog panels use an early plug-in fuse design rather than breakers, and some use proprietary Bulldog breakers that are not interchangeable with anything modern.
How to identify a Bulldog Electric panel
- The panel reads "Bulldog" or "Bulldog Electric"
- The protective devices may be screw-in fuses, plug-in cartridges, or proprietary Bulldog breakers
- The panel itself is often a small rectangular steel box with limited circuit count (often 4–8 spaces)
- Frequently found in basements alongside an old cast-iron meter base
Why it's dangerous
Three reasons. The bus design pre-dates modern arcing standards and is prone to overheating under modern household loads. Replacement breakers and fuses are functionally unobtainable, which means homeowners often substitute incorrect or oversized devices that defeat overcurrent protection. And Bulldog panels are usually too small for modern load — you typically cannot add a single new circuit without overloading the bus.
What NJ Insurance Carriers Do With These Panels in 2026
The insurance landscape has tightened significantly since 2023. As of 2026, here is what we see across the major NJ carriers:
- New policy applications: Most national carriers writing in NJ — the ones you have heard of — will refuse to bind a new homeowner's policy on a home with FPE, Zinsco, Sylvania-Zinsco, Pushmatic, or Bulldog. A few specialty carriers will write at a premium with a written replacement plan attached.
- Existing policies: Carriers are increasingly issuing non-renewal notices at the annual policy anniversary if one of these panels is present, often after a roof or interior inspection flags it.
- Mortgage closings: No insurance binder means no mortgage funding. Buyers under contract on a NJ home with one of these panels frequently learn at the eleventh hour that closing cannot happen until the panel is replaced.
- Claims after a fire: Carriers are aggressive about contesting electrical fire claims where the home was known to have a defective panel. The grandfather clause keeps the panel legal — it does not protect a claim.
What to Do If You Find One of These Panels
- Take a photo of the panel cover and the inside (with the breaker face plate on, not removed). Send it to us. We will identify it for you at no charge.
- Call your insurance carrier. Ask in writing whether your panel is acceptable. Get the answer in writing.
- Get a written replacement quote. A licensed NJ electrician should give you a line-item quote that includes the panel, the UCC permit, municipal inspection, PSE&G or JCPL service coordination, disposal of the old panel, and a written warranty.
- Schedule the replacement before your policy renewal date. Once a non-renewal notice is issued, you have a narrow window to either replace the panel or shop for a specialty carrier — and specialty coverage usually costs more than the panel itself within the first year.
- If you are buying a NJ home with one of these panels, negotiate a seller credit or a pre-closing replacement. We routinely write same-day scope-of-work letters for buyers in inspection contingency. See our realtor page for the process.
Why This List Matters More in NJ Than Most States
NJ housing stock skews old. A huge share of homes in Hudson, Essex, and Bergen Counties were built or significantly remodeled in the same 1950–1990 window when these five panels were heavily marketed. Combined with NJ's tight insurance market and active municipal inspection enforcement, the cost of leaving a defective panel in place is higher here than almost anywhere else in the country. The fix — a one-day panel replacement done by a licensed contractor with a clean municipal inspection — is straightforward, permanent, and almost always cheaper than the insurance, resale, and fire-risk costs of waiting.
