Is a Federal Pacific panel dangerous?
The record points that way, though no federal agency has ruled on it. In 1983 the Consumer Product Safety Commission confirmed that Federal Pacific Stab-Lok breakers fail certain UL calibration tests, then closed its investigation, saying it had too little data to accept or refute the maker's position that the failures are not a household hazard; a 2011 note on its release says it made no determination either way on their safety. Insurers read the same history more strictly: Cincinnati Insurance says the breakers can fail to trip in an overload or short circuit and recommends replacing the whole panel, and AmTrust recommends replacing every Stab-Lok panel and breaker with UL listed equipment.
Did the CPSC recall Federal Pacific Stab-Lok breakers?
The Commission's March 3, 1983 release is a closed investigation, not a recall. It says Commission staff had insufficient data to accept or refute Reliance Electric's position that the failures do not create a household hazard, and estimated it would cost several million dollars to gather that data. A note added on February 18, 2011 says the Commission closed the matter without making a determination as to the safety of the breakers, and advises everyone to take its safety precautions with all breakers and fuses.
Is a Zinsco panel dangerous?
Zinsco's known weak point is the connection between each breaker and the bus bar. Wikipedia's history of the company and Great American Insurance Group describe the same failure: the connection loosens, arcs and overheats, and a breaker can fuse to the bus bar so that it no longer trips. Great American's position is that all Zinsco breakers and panels should be replaced with current UL listed equipment. The damage is usually behind the cover, so a panel that looks fine from the outside is not proof that it is.
How do I know if I have a Federal Pacific panel?
Read the panel door and the label inside it without removing anything. Look for Federal Pacific Electric, Federal Pacific, FPE or Federal Pioneer, and for the word Stab-Lok, which Cincinnati Insurance says is most often near the top between the two rows of breakers. Cincinnati also points to the white strip between the rows, with rounded corners and tick marks between the breaker numbers. The New Jersey court notice in the Federal Pacific class action told owners the same thing: look at the outside of the panel and the inside of the door, and do not remove any breakers.
How do I know if I have a Zinsco panel?
Look for Zinsco, Sylvania or GTE-Sylvania on the door or the label, or the word Magnetrip embossed in the steel cover. Zinsco breakers often have colored handles: InspectAPedia lists light blue for 15 amps, red for 20, light green for 30 and light gray for 40, with some breakers in black. CASA's Zinsco FAQ warns that not every Sylvania or GTE-Sylvania panel is the problem design, so an electrician has to confirm it.
Do I have to replace a Federal Pacific or Zinsco panel in New Jersey?
We found no New Jersey rule that orders an existing panel removed because of its brand. The state's rehabilitation subcode says buildings legally in existence may continue in use and does not require their repair or alteration, except under the unsafe structures rule (N.J.A.C. 5:23-6.2(f)). What forces the job in practice is an insurer that will not write or renew the policy, a buyer's home inspection, or a panel that shows heat damage.
Will homeowners insurance cover a house with a Federal Pacific or Zinsco panel?
Sometimes not. Kin Insurance (updated April 30, 2026) lists Federal Pacific Stab-Lok, Zinsco (including some Sylvania versions), Pushmatic and Challenger panels as ones that can bring a policy denial, a nonrenewal or an exclusion for electrical claims. The Professional Insurance Agents of Wisconsin report that Grinnell Mutual does not accept risks that include any FPE breaker panel. A licensed home inspector in East Hanover, New Jersey writes that some owners cannot get or renew a policy until a known-problem panel is replaced. Ask your insurer what it needs in writing.
Will insurance pay to replace a Federal Pacific or Zinsco panel?
Usually not. Kin says a policy may pay to replace a panel damaged suddenly by a covered event such as a fire, a lightning strike or a power surge, but not a replacement because of age, wear and tear or an upgrade requirement; that cost is the homeowner's. Kin adds that equipment breakdown coverage, where an insurer offers it, covers internal failure but not upgrades or code-required improvements.
Can I just replace the breakers instead of the whole panel?
Not as a fix for these two brands. AmTrust says replacing Federal Pacific Stab-Lok breakers alone is not recommended, even with UL approved breakers, because a panel and breakers of different brands have not been tested together by UL and the enclosure and bus bar have problems of their own. Aftermarket Zinsco-style breakers are available (Wikipedia lists Connecticut Electric among their makers), but Great American recommends replacing all Zinsco breakers and panels, and CASA's FAQ warns of counterfeit replacement breakers sold online.
How much does it cost to replace a Federal Pacific or Zinsco panel in New Jersey?
Malfettone Electric, a North Jersey contractor, publishes $3,500 to $5,500 for a Federal Pacific, Zinsco or Pushmatic replacement in Hudson and Essex County, permit and inspection included. HomeAdvisor's national range for replacing a Federal Pacific or Zinsco panel is $1,500 to $4,000 (updated June 17, 2026). These are market ranges, not MDL prices; MDL gives a written estimate after seeing the panel, the meter and the service.
Do I need a permit to replace an electrical panel in New Jersey?
Yes. New Jersey's list of ordinary electrical maintenance, the work that needs no permit, covers like-for-like receptacle, switch and fixture replacements and repairs to installed equipment, not a panel (N.J.A.C. 5:23-2.7), so the work needs a construction permit first (N.J.A.C. 5:23-2.14). The town's electrical inspector checks the panel and service installation, and on PSE&G service the utility needs the town's certificate of approval, the cut-in card, before it installs the meter and connects service.
Does a new panel need a surge protector and an outdoor disconnect in New Jersey?
Yes, when the panel being replaced is the service equipment. New Jersey adopted the 2023 National Electrical Code effective August 17, 2026. Section 230.67 requires a Type 1 or Type 2 surge protective device on a dwelling service, and section 230.85 requires an outdoor emergency disconnect for one- and two-family houses; both sections say their requirements apply where service equipment is replaced. MDL's panel cost guide explains both items line by line.
Can I get money from the New Jersey Federal Pacific class action?
Not anymore. In Yacout v. Federal Pacific Electric Co. (Superior Court of New Jersey, Middlesex County, Docket L-2904-97), the court ruled in 2002 that Federal Pacific violated the New Jersey Consumer Fraud Act by knowingly distributing breakers that were not tested to meet the UL standards on their label. Claims were limited to owners who had breakers sold between June 29, 1971 and July 1, 1980 installed while they owned the building, the order ruled out later buyers of those homes, and the claim deadline in the court's notice was April 20, 2005.
Do I have to tell a buyer about a Federal Pacific or Zinsco panel?
New Jersey's seller's property condition disclosure does not ask for the panel brand. It asks for the wiring type, the amp service, whether the house has breakers, fuses or both, and whether additions to the service were done by a licensed electrician with permits, and it says the seller must disclose any known material defects even if the form does not address them. Whether a known Federal Pacific or Zinsco panel is one is a question for your attorney or agent; the East Hanover inspector quoted on this page says he calls these panels out in his reports.
Are Federal Pioneer, Challenger and Sylvania panels the same thing?
They are related names, not one product. Federal Pioneer is the Canadian Stab-Lok line, which AmTrust says Schneider Electric makes today. Zinsco was sold to GTE-Sylvania in 1973 and its line was relabeled Challenger in 1978; separately, Federal Pacific's own breaker business took the Challenger Electric name in 1986 (Wikipedia). Kin lists Challenger panels among those insurers may decline. Because labels changed hands, an electrician should confirm the panel and breaker design, not the name alone.
How do I ask MDL about my panel?
Call 973.809.2339 or send the request form on this page with your town, the name on the closed panel door or the label inside the door (do not remove the cover), the main breaker size if you can read it, your utility, and what started the question: an insurer letter, a home inspection report, a sale, or breakers that trip or feel warm.
