Signs You Should Act On This Month
1. The panel is a Federal Pacific Stab-Lok
If you open the panel door and see a rectangular metal box with "FPE" or "Federal Pacific Electric" on the dead-front, you have a known fire hazard panel. Independent testing has shown Stab-Lok breakers fail to trip under overload conditions 25-60% of the time, which means the circuit keeps drawing current while the wire melts inside your wall.
About 1 in 20 Long Island homes we walk still have a Federal Pacific panel. Most homeowner insurance carriers in NY now refuse to renew policies on homes with them. Replace it. Not next year, this year.
2. The panel is a Zinsco or Sylvania-Zinsco
Same story, different brand. Blue or multi-colored breaker handles, "Zinsco" label on the dead-front. Known to fail internally, bus bars arc and melt, breakers fuse in the closed position. Replace.
3. You see scorching, melting, or rust inside the panel
Open the panel door (flip the main off first, or have us do it). If you see any of:
- Brown or black scorch marks around a breaker
- Melted plastic on a breaker handle
- Rust on the bus bars or on the inside of the can
- Insects or mouse droppings inside
...you have active damage. Rust means water has been in the panel, which is a shock hazard. Scorch marks mean a circuit arced. Replace.
4. The panel is warm to the touch
A healthy breaker panel runs at ambient room temperature, even at full load. If you put your hand on the cover and it feels warm — especially warm over a specific breaker — there is a loose connection behind it. That loose connection is arcing and generating heat. It will eventually arc badly enough to start a fire.
Warm panels are one of the fastest "call an electrician today" signs we know. Do not wait.
Signs Your Panel Is Out of Headroom
5. Breakers trip when multiple appliances run
If running the microwave and the toaster at the same time trips a kitchen breaker, or if the dryer kicks off the laundry circuit every third load, or if the AC compressor blows its breaker in July heat — your panel is at or over capacity for the loads in your house.
This is sometimes fixable with a new dedicated circuit (if your panel has room). More often it means the whole panel needs to go up to 200-amp service with dedicated circuits for the high-draw appliances.
6. Lights dim when the AC kicks on
A slight momentary dim when a 3-ton AC compressor starts is normal. A noticeable, multi-second dim across the whole house is not. It means your service entrance cable or panel is undersized for the inrush current.
7. You are adding central AC, a heat pump, a pool, a hot tub, or an EV charger
Each of these adds 30-60 amps of continuous load. A 100-amp panel cannot realistically handle more than one of them without the other loads being pruned. If you are planning any of these, do the panel upgrade first so you do not end up with nuisance trips.
8. Your panel has no room for new breakers
Open the panel. Count the unused slots. If every slot is filled (including tandem "cheater" breakers stacked in singles), your panel is full. Adding circuits requires a sub-panel or — more often the better answer — a full panel upgrade with more slots.
Signs Driven by Time, Not Capacity
9. The panel is older than 40 years
Breaker panels have a design life of about 30-40 years. A 1970s panel is past its design life. Even if it is a well-made Square D or Eaton, the bus bars oxidize, the breakers wear mechanically, and the connection torque drifts.
If your Long Island home was built in 1975 or earlier and still has the original panel, plan the replacement. It does not have to be an emergency, but it should not be a 10-year "someday" either.
10. You have fuses, not breakers
If your house still has a fuse box (round screw-in fuses or cartridge fuses in a pull-out block), you are almost certainly pre-1965. Fuses themselves are not dangerous — they are actually more reliable than breakers — but the panels around them are old, the wire coming in is probably undersized, and the grounding is from an era before grounding rods were standard.
Fuse boxes are also an insurance problem. Many LI carriers will not write a new policy on a home with fuses.
11. You have aluminum branch wiring
Aluminum house wiring (not service-entrance aluminum — that is fine) was used in branch circuits from about 1965-1975. Under a load, the aluminum expands and contracts more than copper, which loosens connections at outlets, switches, and breaker terminals. Loose connections arc. Arcs start fires.
The AlumiConn or CO/ALR fix at every termination is the proper remediation. We often bundle this with a panel upgrade on 1965-1975 LI homes because the panel is usually tired at the same time.
Things to Fix Eventually
Not every panel issue is a fire hazard. Some are just wrong-for-your-life signs:
- Only one or two 240V circuits. Limits you on EV, hot tub, range, dryer, etc.
- No GFCI protection on kitchen/bath/outdoor circuits. Code compliance issue at resale.
- No AFCI protection on bedroom circuits. Required in new construction. Worth adding on renovation.
- No surge protection. A whole-house surge protector at the panel is a $300-$500 add that saves electronics during the next PSEG event.
The Money Question
Short version: $3,200 to $5,800 turnkey for a 200-amp upgrade on Long Island in 2026. See our panel upgrade cost guide for the full breakdown including permits, PSEG coordination, and what pushes you to the high end of the range.
Compared to the cost of a kitchen fire, a homeowner's insurance cancellation, or an inability to install an EV charger later — it is one of the cheapest infrastructure upgrades you can make to a Long Island home.
Next Step
- Open the panel door (do not remove the dead-front cover, just the outer door). Look for the brand name on the label inside.
- Put your hand flat on the panel cover. Warm is bad. Room temperature is fine.
- Count the empty breaker slots. Zero empties = out of capacity.
- Call us for a free walk-through. We will look at the panel, the service mast, the grounding, and the meter. Takes 20 minutes. No pressure.
If the panel is a Federal Pacific or Zinsco, or if it is warm to the touch, do not wait for an appointment. Call us or any licensed Long Island electrician today.
