Are Federal Pacific Stab-Lok Panels Safe?
No. Their breakers can fail to trip during an overload, which is why many insurers decline these homes.

Why insurers flag this panel
Federal Pacific Stab-Lok breakers tested at a much higher failure rate than other brands. The panel can stay energized during an overload that should shut it off. Insurers treat that as a fire risk tied to the panel itself, not your claims record.
What your letter actually means
A non-renewal or cancellation tied to this panel usually isn't about something you did. It means the insurer reviewed the panel brand and decided not to carry that risk. Check the letter's stated reason. It may name the panel directly or just say electrical system.
The deadline on your letter
Your state sets how much notice an insurer must give before coverage ends, and the letter itself states your actual date. Don't wait to see if it resolves. Replacing the panel or lining up new coverage both take time you may not have.
What restores coverage
Most insurers who decline for this reason will reconsider once the Stab-Lok panel is replaced with a current panel. An electrician's report or receipt confirms it. Some insurers will still cover the house with the panel in place, at a higher price or with conditions.
Some insurers still write homes with a Stab-Lok panel in place, others won't touch it at all, and prices between them can differ a lot for the same house. Since the decision to decline isn't about your claims history, a different insurer's underwriting guidelines may treat the panel differently than the one that sent your letter. Checking before your deadline shows what's actually available.
How do you know if you have one
Federal Pacific Electric sold these panels mostly from the 1950s through the early 1980s. If your house was built or wired in that window, open the panel and look at the label. It will say Federal Pacific Electric or FPE, and the breakers often have a red stripe or a distinctive stab-in design where they connect to the bus bar. Some panels were relabeled or sold under other names after the company ran into trouble, so the brand on the door isn't always the end of it. An electrician can confirm what's actually inside in a few minutes.
A permit history or prior inspection report can also tell you. If you bought the house recently, check the inspection report from the sale. Many inspectors note panel brand as a matter of course, even when they don't flag it as a problem. If nothing in your paperwork mentions it and the house was built after 1990, it's unlikely you have one. If you're not sure and can't get into the panel yourself, that's a reasonable thing to ask an electrician to check even outside of a full rewiring job.
Replacing the panel costs money up front, and homeowners sometimes ask whether it's worth doing instead of just finding an insurer who'll cover the house as is. There's no single answer. A full panel replacement is a bigger job than it sounds, since it usually means the main breaker, the breakers for every circuit, and sometimes the meter base all get swapped at once, and a permit and inspection are typically part of it. Coverage with the panel left in place, where it's available at all, often comes with a higher price or an exclusion tied to electrical fire risk, which is its own cost over the years you own the house.
If you decide to replace it, keep every piece of paper the job generates. The invoice, the electrician's license number, the permit, and the final inspection sign-off all matter when you send them to an insurer afterward. A clear paper trail is usually what turns a decline into an approval, and it can also matter later if you ever sell the house and a buyer's inspector asks the same question you're asking now.
Can you fight the non-renewal instead of replacing the panel
Some homeowners try disputing the letter rather than dealing with the panel, especially if they've had Stab-Lok breakers for years without a problem. That argument rarely works with the insurer who sent the letter. The decision is based on the panel's known failure rate across many houses, not on anything specific to yours, so your own history with it doesn't change their underwriting position.
An electrician's inspection showing the panel tests fine won't usually reverse it either. The concern isn't whether the breakers work today. It's whether they'll trip correctly during a future overload, and that's a design issue affecting the brand, not something a one-time test can rule out. A letter from an electrician saying the panel is functioning normally addresses a different question than the one the insurer is asking.
What sometimes works is asking the insurer directly what would change their decision. A few will cover the house if an electrician adds specific safeguards, like a surge protector at the panel or an upgraded main breaker, short of a full replacement. Most won't, since the panel itself is the issue. It costs nothing to ask before you commit to a full replacement or start shopping for another insurer.
If the answer is no, the practical options are replacing the panel or finding an insurer whose guidelines treat Stab-Lok panels differently. Appealing past that point usually just burns the time you have before your coverage ends. Your state sets how much notice you were owed, and the letter states your actual deadline, so that's the date to plan around regardless of how the appeal goes.
Before your coverage ends
Check your letter for the exact date and pull up your panel's label. Either one, an electrician's confirmation of a Stab-Lok panel or proof it's already been replaced, is what an insurer will ask for next.
