If you own a home in German Village, Ohio, or nearby communities like Westerville, Powell, or Dublin, there’s a chance your electrical system may be hiding a serious safety risk. Thousands of older Central Ohio homes still rely on outdated Federal Pacific or Zinsco electrical panels, and many homeowners don’t realize these panels have a long history of failure and fire hazards.
That’s where a panel upgrade becomes more than just an option — it becomes a necessity. In this guide, we’ll explain why Federal Pacific and Zinsco electrical panels are dangerous, how to identify them, what a safe replacement looks like, and how Electric Medic can help homeowners in Worthington and across Columbus, OH, protect their families.
What Is an Electrical Panel and Why Does It Matter?
Your home’s electrical panel is the distribution hub for all power entering your house. Every light switch, outlet, appliance, and HVAC unit depends on it to work safely.
- Breaker Panels (Modern): Use resettable switches that trip safely when overloaded.
- Fuse Panels (Older): Use fuses that blow and must be replaced.
- Federal Pacific and Zinsco Electrical Panels: Outdated breaker panels known for high failure rates.
When panels fail, they may not shut off electricity during an overload, leading to overheated wires, melted breakers, or even electrical fires.
What Makes Federal Pacific and Zinsco Electrical Panels So Dangerous?
The Federal Pacific Electric (FPE) Stab-Lok Panel
Federal Pacific panels were incredibly popular and are found in an enormous number of homes built between the 1950s and 1980s. Their primary danger lies in the design of their Stab-Lok breakers.
- The Failure to Trip: The core job of a circuit breaker is to sense an overload and instantly “trip” (shut off) to prevent wires from overheating. Extensive testing has shown that a significant percentage of FPE Stab-Lok breakers simply fail to trip. This means during an overload, electricity continues to flow unchecked, melting wire insulation and igniting surrounding materials.
- The Illusion of Safety: The most sinister part? The breaker switch might still look like it’s in the “ON” position even when it has failed internally. This gives homeowners a false sense of security.
- Other Hazards: These panels are also known for:
- Breakers that don’t fit securely, leading to arcing and heat buildup.
- Aluminum bus bars can corrode and overheat.
- A legacy of deception, the company was found to have knowingly falsified its testing data to meet safety standards.
The Zinsco Electrical Panel (or Sylvania Panel)
Zinsco electrical panels (later sold under the name Sylvania) are the other major brand known for catastrophic failures. They were also installed extensively during the mid-20th century.
- The Melting Bus Bar: The primary failure point in a Zinsco electrical panel is the connection between the breaker and the main bus bar (the metal strip that distributes power). This connection is poorly designed, leading to overheating. Over time, the intense heat can actually fuse the breaker to the bus bar.
- A Permanent Connection: Once fused, the circuit becomes permanently “on,” completely bypassing the breaker’s safety function. Even if you flip the switch to “OFF,” electricity will still flow to the circuit, creating an immense and undetectable fire hazard.
- Visible Signs of Damage: You might see signs of this failure, such as discoloration or melting on the breakers themselves or on the plastic panel interior.
How to Identify a Federal Pacific or Zinsco Electrical Panel in Your Columbus Home
Knowing what to look for is the first step toward safety.
Identifying a Federal Pacific Panel:
- The name “Federal Pacific” or the abbreviation “FPE” is usually prominently displayed on the panel cover.
- The breakers are typically a distinctive red color, though they can also be black or tan.
- The switches are often thinner and longer than modern breakers.
Identifying a Sylvania or Zinsco Electrical Panel:
- Look for the “Zinsco” or “Sylvania” logo on the front.
- The breakers are often a bright, two-tone color scheme—like a light blue with a red tip or a solid magenta color.
- The design has a distinct, somewhat dated 1970s aesthetic.
If you see any of these signs, please do not attempt to remove the cover yourself. The act of disturbing a failing panel can itself be dangerous. The safest next step is to call a licensed electrician for a professional assessment.
The Only Solution: A Complete Panel Upgrade
There is no safe “fix” for these panels. Replacing a few breakers does nothing to address the fundamental design flaws in the bus bar and the panel itself. The only way to eliminate the risk is with a full electrical panel box replacement.
A modern panel upgrade provides:
- Real Safety: Modern panels from brands like Square D, Eaton, or Siemens are UL-listed and rigorously tested to reliably trip and prevent fires.
- Peace of Mind: Stop worrying every time you flip a switch or plug in an appliance.
- Insurance Compliance: Many insurance companies will refuse to insure a home with a known FPE or Zinsco electrical panel. Upgrading it removes this liability and can sometimes even lower your premium.
- Increased Home Value: A new, code-compliant 200-amp electrical panel is a valuable asset and a strong selling point.
- Power for Modern Life: These upgrades often coincide with a service upgrade to 200 amps, providing enough power for all your modern devices and future needs.
Some homeowners ask if replacing Federal Pacific breakers or Zinsco breakers with “new” ones solves the problem. Unfortunately, it doesn’t. Replacement parts are scarce, often unreliable, and don’t address the design flaws.
The safest choice is a full panel upgrade, which means replacing the entire electrical panel with a modern breaker box built to today’s standards.
Benefits of a Panel Upgrade:
- Improved Safety – Breakers trip properly to prevent overheating.
- More Power Capacity – Upgrade from 100 amps to a 200-amp breaker box to handle modern appliances, HVAC, and EV chargers.
- Peace of Mind – No more worrying about hidden fire hazards.
- Higher Resale Value – A house electrical panel upgrade is a selling point for buyers and home inspectors.
How to Tell If You Need a Panel Upgrade in Worthington
Consider scheduling an inspection if you notice:
- Your panel is labeled Federal Pacific, Zinsco, or Sylvania.
- Breakers frequently trip, buzz, or feel hot to the touch.
- Lights flicker when using appliances.
- You still have a 60-amp or 100-amp service panel.
- You’re planning a remodel, basement finish, or EV charger install.
Homeowners in Worthington’s older neighborhoods — like Colonial Hills and Wilson Hill — are especially likely to have outdated panels.
How Long Does a Panel Upgrade Take?
Most panel upgrades in Columbus, Ohio, take 6–10 hours, depending on the complexity.
Typical Timeline:
- Morning: Power shutoff, old panel removal
- Midday: Install new 200-amp electrical panel, reconnect circuits
- Afternoon: Inspection and utility approval, power restored
