A panel that's "just full" is different from a panel that's dangerous — but most homeowners can't tell the difference from the outside. These seven signs are the ones licensed electricians actually look for.
- Breakers trip repeatedly under normal load — a breaker that trips doing its job (overload, short) once in a while is normal. One that trips constantly, even on light loads, usually means a failing breaker or a panel that's undersized for the house.
- Breakers that never trip — far more dangerous than one that trips too often — a breaker that doesn't cut power during a real overload isn't doing its one job. This is the specific, documented failure mode of Federal Pacific and Zinsco panels; see our full explainer.
- A warm panel, scorch marks, or a burning smell — not a scheduling decision. Kill the main breaker and call an electrician the same day — see electrical repair & troubleshooting.
- Lights flicker or dim when the AC or a large appliance starts — can point to a panel or service connection that's struggling to deliver current — see our full breakdown of why this happens.
- Your panel is a Federal Pacific or Zinsco brand — documented fire risks that most Florida insurers won't cover regardless of how the rest of the panel looks. See panel upgrades for what replacing one involves.
- You're relying on power strips and extension cords because you're out of circuits — a sign the panel doesn't have room for your home's actual electrical load — and definitely not room for a generator transfer switch or EV charger circuit.
- The home is 30+ years old and the panel has never been replaced — not automatically a problem, but exactly the profile Florida insurers ask about at renewal — see our guide to the 4-point inspection.
If more than one of these sounds familiar, the safest next step is a free estimate from a licensed local electrician — a panel inspection is quick, and it settles the question either way.
