When your contractor tells you the panel needs to be replaced, one of the first questions you'll ask is: what brand should I get? It's a reasonable instinct — brand research is how you make most purchasing decisions. But with electrical panels, the brand question has two very different answers depending on whether you're buying a new panel or figuring out what's already in your house.
For new installations, the major current brands are all acceptable and the choice is mostly your electrician's call. For existing panels, brand identity can be the difference between a normal home and one that insurance companies refuse to cover. This article covers both: what your contractor will likely install and why, and which legacy brands are flagged as hazardous and why that matters for your coverage, your home sale, and your family's safety.
Why brand matters (and when it doesn't)
For a panel being installed today, brand matters in a few practical ways: busbar material (more on that below), breaker availability, and price. What it does not affect in any meaningful way is reliability between the major current manufacturers. Electricians who work on residential panels frequently will tell you this question is roughly equivalent to asking whether Ford or Chevy makes a better pickup — you'll get a strong opinion, but the real-world difference for the average homeowner is negligible.
Where brand becomes critically important is with panels manufactured before roughly 1990. A handful of brands produced during that era have documented failure rates that go well beyond normal aging — their breakers don't reliably trip under overload, which eliminates the panel's primary safety function. Those brands belong in a separate category entirely, not on a comparison chart with Square D and Siemens.
The safe current brands
Four manufacturers dominate the residential panel market in the US. All are safe, all are code-compliant, and all have readily available replacement breakers.
Square D — The most recognized brand in residential electrical, made by Schneider Electric. Square D sells two panel lines: the QO (premium, copper busbar, snap-indicating breakers) and the Homeline (value tier, aluminum busbar). When electricians and homeowners refer to "Square D" as the gold standard, they typically mean the QO line. The Homeline is a sound product but uses an aluminum busbar, which is a meaningful distinction covered in the next section.
Siemens / Murray — Siemens acquired Murray, so these are now the same product line with the same breakers. Siemens panels are widely stocked at electrical supply houses and are a common electrician preference partly because the neutral bar screws come pre-backed-out from the factory, which speeds up installation. Siemens is a solid choice for any residential upgrade.
Eaton (Cutler-Hammer) — Eaton sells panels under the Cutler-Hammer name. Like Square D, Eaton has a premium line (the CH, copper busbar) and a value line (the BR, aluminum busbar). The CH line carries a lifetime warranty on breakers, which is a genuine differentiator. The BR is a capable product but again, aluminum busbar.
GE / ABB — General Electric's residential panel line is less commonly specified than the others but is not deficient in any meaningful way. GE panels typically use copper busbars and galvanized steel enclosures, which makes them a reasonable choice for damp locations. The brand has lower mindshare among residential electricians simply because supply houses tend to stock less of it.
Brand availability varies by region. What your electrician installs often depends on what their supply house stocks. In some markets, Siemens is the default; in others, Square D dominates. There's no wrong answer among the major brands — regional availability is a legitimate reason to go with whatever your electrician carries.
Copper vs aluminum busbar: the distinction that actually matters
The busbar is the metal bar inside the panel that distributes power to each breaker slot. The material it's made of — copper or aluminum — is the one technical distinction worth understanding as a homeowner, because it affects longevity in moisture-prone environments.
Copper busbars are more corrosion-resistant and handle repeated thermal cycling (heating and cooling with load changes) better over time. Panels with copper busbars: Square D QO, Eaton CH, GE, Siemens (most lines). Panels with aluminum busbars: Square D Homeline, Eaton BR.
In a dry interior location — a utility closet, a finished basement — an aluminum busbar panel will last just as long as a copper busbar panel and will give you no problems. The material difference becomes relevant in laundry rooms, unfinished basements with humidity, and outdoor-adjacent installations. Electricians who work in coastal markets or high-humidity climates often specify copper-busbar panels for this reason.
The bottom line: if your electrician quotes you a Homeline or BR panel, that's not a red flag — both are widely installed with excellent track records. If you're in a damp location and want to specify a copper-busbar panel, Square D QO or Eaton CH are the requests to make.
Who actually picks the brand — and whether you can influence it
In most residential panel replacements, the electrician chooses the brand. This is standard practice, not a decision being made at your expense. Electricians develop working preferences based on what their supply house stocks, what they know how to install quickly, and which brands they've had good experiences with. All of those factors benefit you as the customer — a panel brand your electrician knows well gets installed correctly.
You can absolutely specify a brand or line if you have a preference. If you already have a Square D panel and want to preserve breaker compatibility, asking your electrician to match the brand is reasonable. If you want a copper-busbar panel in a damp location, saying so gets you a QO or CH instead of a Homeline or BR. Electricians won't balk at this — it's a normal ask.
One red flag worth knowing: if a contractor pushes hard for a brand you've flagged as hazardous (Federal Pacific, Zinsco) or tries to sell you "replacement breakers" for a known-problematic panel rather than replacing the panel itself, walk away. Aftermarket replacement breakers for these panels have their own documented failure problems and are not an adequate fix.

Hazardous legacy brands
The following brands are in a different category than the "brand preference" discussion above. These are panels with documented safety problems — not aging, not obsolescence, but specific failure modes that have been confirmed through testing and linked to residential fires. If your home has one of these panels, the question isn't which brand to upgrade to. It's how soon to replace it.
Federal Pacific Electric (FPE) / Stab-Lok
Federal Pacific Electric manufactured panels under the Stab-Lok name from roughly 1950 through 1980. These panels were installed in millions of US homes. The problem: Stab-Lok breakers have a documented failure rate under overload and short-circuit conditions — the breaker doesn't trip when it should, allowing wiring to continue heating toward ignition.
The CPSC confirmed in testing that FPE breakers failed UL calibration requirements. Independent research has found failure rates significantly above what's considered acceptable for a safety device. The breakers may appear functional during normal use — the failure mode shows up under stress, which is exactly when you need the breaker to work.
FPE panels are identifiable by the "Federal Pacific Electric" or "FPE" label on the panel door, and "Stab-Lok" printed on the breakers themselves. They were also sold under the Reliance Electric name after Reliance acquired FPE.
Aftermarket "fix" to avoid: Some contractors offer to replace Stab-Lok breakers with aftermarket UBI (Connecticut Electric) replacements rather than replacing the panel. Independent testing has found that UBI replacement breakers for Stab-Lok panels fail UL standards at a higher rate than the original FPE breakers. Breaker-swap is not an adequate solution — full panel replacement is the correct repair.
Zinsco / Sylvania / GTE-Sylvania
Zinsco panels were common in homes built from the 1950s through the 1970s. The failure mode is different from FPE but equally serious: Zinsco breakers can overheat and physically melt onto the aluminum busbar. Once this happens, the breaker is fused in place and cannot trip at all, even under a direct short. The panel looks fine from the outside while being unable to protect the circuit it's supposed to protect.
Zinsco panels were also sold under the Sylvania and GTE-Sylvania names, so don't assume a "Sylvania" label means something different. The underlying panel design is the same. These panels are no longer considered safe in any configuration and are not repairable with replacement breakers. If you have one, see the full guide to Federal Pacific and Zinsco panel replacement for what the process looks like and what it costs.
Pushmatic / ITE
Pushmatic panels, sold under the ITE brand, used a button-style breaker instead of a toggle. They were manufactured into the 1980s. The failure mode here is less catastrophic than FPE or Zinsco — Pushmatics don't have the same documented fire-hazard profile — but replacement breakers are no longer manufactured, making repairs effectively impossible. Any electrician who opens a Pushmatic to work on it will find that parts simply aren't available. Replacement is the only viable path once service is needed.
Pushmatic panels are easy to identify: the breakers are round buttons, not toggles, and the brand name appears on the panel face.
The insurance problem
Insurance companies have become increasingly aggressive about Federal Pacific and Zinsco panels. The practical consequences for homeowners fall into three categories:
Coverage refusal on new policies is now common. If you're moving into a home with an FPE or Zinsco panel and your insurance carrier runs a home inspection, a growing number will decline to write the policy unless you commit to replacement. This is not a negotiating position — it's a hard underwriting rule at many companies.
Home sale complications are the other major trigger. Buyers' lenders and home inspectors routinely flag these panels. A home inspection that surfaces an FPE or Zinsco panel often results in the buyer demanding replacement as a condition of purchase, or walking away. If you're selling a home with one of these panels, you will likely face this conversation.
Existing policy cancellation or premium increases are the third scenario. Some carriers who discover an FPE or Zinsco panel during a policy renewal inspection will non-renew coverage or significantly raise the premium. The timing is unpredictable — policies written before the panel was inspected may continue until renewal.
If you're unsure what your insurance carrier's position is on your panel, call them directly and ask. The question is: "Does my policy exclude or restrict coverage for homes with Federal Pacific or Zinsco electrical panels?" Getting a clear answer before you need to file a claim is worth the five-minute phone call.
How to identify your panel brand
Your panel's brand is printed on the panel door or the panel face, typically near the main breaker. Look for the manufacturer's name (Federal Pacific Electric, Zinsco, Sylvania, Square D, Siemens, etc.) and the panel series name (Stab-Lok, QO, Homeline, CH, BR).
A few identification notes that cause confusion: "FPE" on breakers means Federal Pacific Electric — not a safe brand. "Sylvania" or "GTE-Sylvania" on a panel indicates a rebranded Zinsco — not a separate product line. "Murray" on a panel is now a Siemens product — safe. "Pushmatic" or "ITE" indicates a Pushmatic panel — not hazardous in the same way as FPE/Zinsco, but non-repairable.
If the label is missing or worn off, a licensed electrician can identify the panel by the busbar design, breaker style, and cabinet construction in a few minutes. Don't guess — a misidentification in either direction has real consequences.
What to do if you have a hazardous panel
If your home has a Federal Pacific or Zinsco panel, the path forward is replacement by a licensed electrician who will pull a permit for the work — and knowing what to ask before you hire is worth doing before you get quotes. This is not optional — panel replacement without a permit means no inspection, which means no confirmation the new panel was installed correctly, which means you've replaced one risk with an unknown one.
The typical cost for a panel replacement runs $1,500–$4,000 depending on your current panel's amperage, whether your service entrance needs upgrading, and your region's labor rates. See the full cost breakdown for a detailed look at what drives the price up or down.
If you're selling a home with an FPE or Zinsco panel, get the replacement done before listing rather than waiting for a buyer's inspector to find it. The negotiating leverage shifts significantly once a buyer's inspection report documents the panel — you'll generally pay more for the work under deadline pressure than you would have on your own timeline.
