Federal Pacific and Zinsco Panels: What Lubbock Homeowners Should Know
Federal Pacific and Zinsco are two panel brands that come up in home inspections, insurance applications and home sales. If you own an older house in Lubbock, TX, you may see one of the names on an inspection report or hear it from an insurance agent. This guide covers how to tell what you have, what federal regulators actually said, how insurers treat these panels, and what replacement typically costs.
About 28% of Lubbock homes were built in the 1960s and 1970s (ACS 2020–24 5-year estimates). There is no local data on how many of them have either brand, so the only way to know is to look at the label.
Look, don't open. You can read the label on the inside of the panel door without removing anything. Do not take off the inner cover (the dead front) or touch breakers or wiring. Panel work is a job for a licensed electrician, and the service conductors feeding the panel are live even with the main breaker off.
How to tell which panel you have
- Open the outer door of the breaker panel and look for the manufacturer's label, usually on the inside of the door or along the edge.
- Federal Pacific panels may say "Federal Pacific Electric" or "FPE". Their breakers are often marked "Stab-Lok".
- Zinsco panels carry the Zinsco name on the label. Some older panels have faded or missing labels.
- Take a clear photo of the label and the breakers with the door open. It helps an electrician or your insurance agent, and you can mention it when you request quotes.
- If you can't tell, a licensed electrician can identify the panel during a visit.
Are Federal Pacific panels dangerous?
The U.S. Consumer Product Safety Commission looked into Federal Pacific Stab-Lok breakers in the early 1980s. In 1983 it announced it was closing "its two year investigation into Federal Pacific Electric Stab-lok type residential circuit breakers," saying the data "does not establish that the circuit breakers pose a serious risk of injury to consumers" (CPSC statement, revised 2011). The CPSC also said its data were limited and that it had decided not to commit further resources. Its advice for homeowners was short: "When in doubt, consult a licensed electrician."
Insurers can take a different view. One insurer's 2019 safety bulletin describes Stab-Lok breakers as having design flaws and cites older testing in which some breakers failed to trip. It says the panels were installed from 1960 to 1985. That is an insurer's position, not a federal finding, but it explains why an agent may ask about your panel.
The honest summary: the CPSC closed its investigation without finding a serious risk established, and some insurers still treat these panels as a concern. A licensed electrician can evaluate yours and tell you what they see.
Is a Zinsco panel safe?
No CPSC recall or official finding on Zinsco panels turned up in our research. What does exist is insurer interest: some insurers ask about older panel brands such as Zinsco and Federal Pacific when writing or renewing a policy. If you have a Zinsco panel, ask your agent what they need, and have a licensed electrician look at its condition.
| Federal Pacific (Stab-Lok) | Zinsco | |
|---|---|---|
| Federal finding | CPSC closed its investigation in 1983; data did not establish a serious risk | No CPSC recall or finding located |
| Insurer stance | Some insurers treat it as a concern and may ask about it | Some insurers ask about it |
| Reasonable next step | Ask your agent; have a licensed electrician evaluate it | Ask your agent; have a licensed electrician evaluate it |
Insurance, inspections and selling a home
These panels most often come up at three moments: a new insurance policy, a renewal inspection, or a buyer's home inspection. A few practical steps help in each case.
- Ask your agent in writing what they need: an evaluation letter from a licensed electrician, a replacement, or nothing at all. Requirements vary by company.
- If a buyer's inspector notes the panel, get an electrician's evaluation and a written quote so both sides are working from the same facts.
- Keep the permit and final inspection record if the panel is replaced. It is useful at sale time.
Should you replace a Federal Pacific or Zinsco panel?
That depends on the panel's condition, what your insurer requires, and whether the house needs more capacity anyway. Many 1960s and 1970s Lubbock homes have 100-amp service, and an EV charger, a larger AC unit or a kitchen remodel can push owners toward a 200-amp upgrade at the same time. A licensed electrician can tell you whether a same-size replacement or an upgrade makes sense.
Published national cost-guide estimates (2025–2026), not quotes:
| Job | Typical range | Source |
|---|---|---|
| Panel replacement, same amperage | $518–$2,193 (avg ≈ $1,347) · $1,400–$2,800 | Angi · HomeGuide |
| Panel upgrade, 100 to 200 A | $1,300–$4,500 | HomeGuide · Fixr |
| City of Lubbock electrical permit | $50 minimum | City fee schedule, FY 2023–24 |
Quotes come from independent contractors, not this site. A replacement usually needs a permit and inspection, and an upgrade may involve the meter base. Lubbock Power & Light owns the meter and coordinates disconnect and reconnect on its side; the electrician handles everything on your side. More detail is on the panel upgrade and replacement page and the Lubbock electrician cost guide.
Older homes with these panels sometimes have other era-specific questions. If your house dates from 1965 to the mid-1970s, read our post on aluminum wiring in Lubbock homes, and see rewiring and aluminum wiring for what that work involves.
Texas rules that apply
Texas requires electrical contractors and electricians to be licensed by TDLR (Texas Occupations Code Chapter 1305). Check any license at tdlr.texas.gov/LicenseSearch and look for the contractor's TECL number on the truck and the written proposal. Texas lets an owner who lives in the home do some of their own electrical work where the city doesn't regulate it, but Lubbock requires a homeowner permit and inspection; check with City of Lubbock Building Safety. Panel and service work is not a homeowner project. The City of Lubbock enforces its adopted NEC with local amendments (the 2020 NEC per a 2024 ordinance); the state code moved to the 2026 NEC on Sept. 1, 2026. Ask the contractor which edition applies to your permit.
Questions to ask the electrician
- What is your TECL number, and can I see your certificate of insurance?
- Do you recommend evaluation, replacement or an upgrade, and why?
- Does the quote include the permit, the meter base if needed, and coordination with LP&L?
- Is there a trip or diagnostic fee for the evaluation?
- Can I get a written, itemized quote, and how long will the power be off?
To compare options, request a free quote and mention the panel brand and a photo if you have one. Lubbock Electrician Pros is a free quote service; independent licensed electricians serving Lubbock reply on their own schedules.
