Does Your Home Have a Dangerous Electrical Panel?
Certain panel brands installed in millions of homes from the 1950s through the 1990s have known safety defects. If your home has one, Harrison Electric can evaluate it and tell you exactly what your options are.
Why some older panels are a genuine safety risk
Your panel's job is to protect your home. When a circuit draws more power than its wiring can safely handle, the breaker trips — cutting power before wiring overheats or a fire starts. A panel that fails to trip is a panel that cannot do its only job.
Modern panels are designed and tested to trip reliably. Several older brands were not. Independent testing and decades of field reports from electricians and home inspectors have documented failure rates that pose real fire and shock hazards. These panels can operate without incident for years — and then fail at exactly the wrong moment.
Panel brands with documented safety concerns
If your home was built between 1950 and 1990 and the panel has never been replaced, it is worth knowing what you have.
Federal Pacific Electric (FPE) Stab-Lok
The most widely documented problem panel in the United States. Installed in millions of homes from the 1950s through the 1980s. A New Jersey court found that FPE knowingly distributed breakers that did not meet UL testing standards. Independent testing found these breakers fail to trip at rates far exceeding acceptable limits. Harrison Electric recommends immediate evaluation for any home with an FPE Stab-Lok panel.
Zinsco and GTE-Sylvania
Common in homes built in the 1960s and 1970s. Zinsco breakers are known to melt to the bus bar — meaning the breaker physically cannot trip even if you try to switch it off manually. Experts estimate that as many as 25% of all Zinsco breakers could fail to trip in response to an overload. Zinsco panels often have brightly colored breaker toggles — red, blue, or green.
Challenger
Produced in the 1980s and 1990s. Subject to recalls in 1988 and 2014 for overheating and melting under load.
Pushmatic and Bulldog
Identified by push-button breakers rather than toggle switches. These panels are old, difficult to service, and prone to failure due to age alone.
Warning signs that warrant a call today
You don't need to open your panel to identify red flags. Call Harrison Electric if you notice any of the following:
- Burning smell or unusual odor from the panel area
- Breakers that trip frequently or won't stay reset
- Flickering lights or unexplained power fluctuations
- Rust, corrosion, or discoloration on or around the panel
- Buzzing or sizzling sounds near the panel
- Your home was built between 1950 and 1990 and the panel has never been replaced

Frequently Asked Questions About Unsafe and Outdated Electrical Panels
Common questions from Minneapolis and Twin Cities homeowners about dangerous panel brands.
How do I know what brand my panel is?
- The brand name is typically printed on the panel door or on the breaker handles. If you see Federal Pacific, Stab-Lok, Zinsco, Sylvania, or Challenger, call Harrison Electric for an evaluation. If you're not sure what you're looking at, a photo sent to us before you schedule can often help identify it.
Can I just replace the individual breakers instead of the whole panel?
- For most of these panel brands, replacement breakers are no longer manufactured. Aftermarket alternatives may not be safe or code-compliant. Harrison Electric recommends full panel replacement for FPE and Zinsco panels — it is the only solution that reliably addresses the underlying safety problem.
Does panel replacement require a permit?
- Yes. Panel replacement in Minnesota requires a permit and a city inspection after the work is complete. Harrison Electric handles the permit process as part of every panel replacement. You do not need to manage this yourself.
