Federal Pacific (FPE) & Zinsco Panel Replacement in West Palm Beach, FL
Many older West Palm Beach homes still have a Federal Pacific (FPE) Stab-Lok or Zinsco electrical panel. These panels were installed in millions of homes from the 1950s through the 1980s, and today they are among the most common reasons a home fails a 4-point insurance inspection. Many electricians and home inspectors consider them a fire risk. Nassif Electric has handled Federal Pacific panel replacement across South Florida since 1976. As a Florida statewide licensed unlimited electrical contractor (License EC13001410), we remove unsafe panels and install modern, code-compliant breaker panels, with the permit, inspection, and FPL coordination included. Every replacement comes with a free electrical safety inspection. Not sure what brand your panel is? Send us a photo of the panel label, or call 561-582-2600 to book a free inspection.
How to Identify a Federal Pacific (FPE) Panel
Open the panel door (don’t remove the inner cover) and look for these signs:
- The words “Federal Pacific Electric”, “FPE”, or “Federal Pacific” on the door or the label inside
- The word “Stab-Lok” printed on the label or the breakers
- Distinctive breakers, often with a red or orange stripe or tip on the handle
- Panel model numbers that often begin with “NA” or “NB”
- Homes built or last updated roughly between the 1950s and the late 1980s
Stab-Lok-style breakers were also sold under other brand names. If you’re unsure, a licensed electrician can confirm it quickly during a free inspection.
Why Federal Pacific Panels Are Considered Dangerous
A circuit breaker has one job: to trip and cut power when a circuit overloads or shorts. The main concern with Federal Pacific breakers is that some may fail to trip when they should. That can let wires overheat inside your walls.
- In 1980, FPE’s parent company reported to the U.S. Consumer Product Safety Commission (CPSC) that many FPE breakers did not fully meet UL requirements. CPSC testing confirmed that the breakers failed certain UL calibration tests.
- The CPSC closed its investigation in 1983 without deciding whether the breakers were safe. It said it lacked the data to link the failures to a hazard and that a full study would cost several million dollars.
- In 2002, a New Jersey Superior Court ruled that FPE knowingly distributed breakers that had not been tested to meet the UL standards shown on their labels.
Because there was never a formal recall, there’s no manufacturer replacement program. Homeowners pay for replacement themselves. Many electricians, home inspectors, and insurers recommend replacing these panels rather than waiting for a failure.
Zinsco Panel Replacement
Zinsco panels, some also sold as Sylvania-Zinsco, were common in homes built in the 1950s–1970s. The main issue is the connection between the breakers and the aluminum bus bars. Over time, those connections can loosen, overheat, arc, and even fuse together, so a breaker may stay “on” even after it trips.
Signs of a Zinsco panel: the Zinsco or Sylvania name on the label, and brightly colored breaker handles (often blue, green, or red) that sit in a row. Scorch marks, a burning smell, or warm breakers mean the panel needs attention right away.
Other Unsafe Panels We Replace
Panel | Common concern |
Federal Pacific (FPE) Stab-Lok | Breakers that may not trip under overload; failed UL calibration tests |
Zinsco / Sylvania-Zinsco | Breakers can overheat or fuse to the aluminum bus bar |
Challenger | Some Challenger breakers were subject to a recall; overheating reported in certain panels |
Pushmatic (Bulldog / ITE) | Obsolete design, stiff breakers, costly or hard-to-find parts |
Fuse boxes | Not enough capacity, risk of oversized fuses, and often uninsurable |
Corroded or storm-damaged panels | Rust, water intrusion, or burned connections |
Whatever the brand, unsafe panel replacement follows the same principle: remove the risk entirely and install a modern panel with current AFCI/GFCI protection.
Can You Just Replace the Federal Pacific Breakers?
We don’t recommend it. Replacement Federal Pacific breakers are either old stock, used parts (often sold online), or third-party breakers designed for Stab-Lok panels. None of these options fixes the underlying panel, and many insurers still reject homes with an FPE panel no matter which breakers are installed. Replacing the whole panel with a modern load center from a current, widely available brand is the safer choice and lasts much longer.
Florida Insurance & Home Sales
In Florida, older homes typically need a 4-point inspection to get or renew homeowners insurance. Many insurers will decline or not renew a policy when the inspection finds a Federal Pacific, Zinsco, or similar panel. These panels also come up often in home inspections and can complicate a sale or financing. After we replace the panel, you receive the finished permit and paperwork to show your insurer or buyer.
How Much Does Federal Pacific Panel Replacement Cost?
In the West Palm Beach area, Federal Pacific panel replacement usually costs about $1,800 to $3,000 for a same-amperage swap, and about $3,000 to $6,000 if you also upgrade to 200 amp service. Zinsco panel replacement cost is similar.
Unsafe panel replacement job | Typical range* |
FPE or Zinsco panel replacement, same amperage | $1,800 – $3,000 |
FPE / Zinsco replacement + upgrade to 200 amp service | $3,000 – $6,000 |
Replacement + new meter can or service entrance | Add $800 – $2,000+ |
FPE / Zinsco sub-panel replacement | $800 – $1,800 |
Add-ons: whole-home surge protector, generator inlet | Quoted separately |
What affects the price: your panel’s amperage and number of circuits, whether you upgrade to 200 amps, the condition of the wiring and grounding, AFCI/GFCI breakers required by current code, whether the meter can also needs replacing, and permit fees for your city.

Frequently Asked Questions
In the West Palm Beach area, most FPE panel replacements cost about $1,800 to $3,000 for a same-amperage swap, or $3,000 to $6,000 if you also upgrade to 200 amps. We give you a free written estimate after an inspection.
No. The CPSC investigated FPE Stab-Lok breakers and confirmed they failed certain UL calibration tests, but in 1983 it closed the investigation without deciding whether they were safe. Because there was no recall, there’s no manufacturer program, and homeowners pay for replacement themselves.
Not every FPE panel has failed, but there’s no reliable way to tell which breakers will fail to trip. That’s why most electricians and insurers recommend replacing them. We can inspect yours and explain your options.
It’s possible to find compatible or used breakers, but it doesn’t solve the underlying panel concerns, and many insurers still won’t accept an FPE panel. Replacing the whole panel is the safer, longer-lasting solution.
FPE panels are replaced with a modern load center from a current manufacturer, such as Square D, Eaton, or Siemens. We choose a brand based on your home’s needs and parts availability.
Usually not. A planned replacement is considered maintenance. However, many Florida insurers require the panel to be replaced before they will issue or renew a policy.
Zinsco panels are widely considered a safety concern because breakers can overheat or fuse to the aluminum bus bar and may not trip. We recommend replacement, especially if you see heat marks or smell burning.
Most replacements are done in one day, with power off for roughly 4–8 hours. Adding a 200 amp service upgrade can make the day a little longer.
Usually, no. Your existing circuits are reconnected to the new panel. We only recommend rewiring if we find damaged or unsafe wiring.
