7 Signs Your Delaware Home Needs an Electrical Panel Upgrade

Your electrical panel is the heart of your home's electrical system. Many homes in Wilmington, Dover, Newark and across Sussex County still run on 60 or 100 amp service that was designed decades before EV chargers, heat pumps, hot tubs and home offices. Here is how to know if you need an electrical panel upgrade.

1. Breakers trip constantly

A breaker that trips whenever you run the microwave and the toaster is telling you the circuit — or the whole panel — is overloaded. Occasional tripping is protection working; constant tripping is a capacity problem.

2. You still have a fuse box

Fuse boxes are safe when maintained, but they are almost always 60 amp service and cannot support a modern home. Most insurers now require a breaker box replacement.

3. Your panel is a Federal Pacific, Zinsco or Sylvania

These brands have documented failure rates where breakers fail to trip. If your panel says Federal Pacific Stab-Lok, Zinsco or GTE Sylvania, replacement is strongly recommended.

4. Lights dim when appliances start

Dimming when the AC or dryer kicks on means voltage is sagging under load — a classic sign of undersized service.

5. Warm breakers, buzzing or rust

Any heat, buzzing, scorch marks or corrosion at the panel is a safety issue. Call an emergency electrician right away.

6. You are adding an EV charger, hot tub or heat pump

A Level 2 EV charger alone can need a 50 amp circuit. Most 100 amp panels simply do not have the room.

7. Your home is over 30 years old and has never been upgraded

Even without symptoms, a 30+ year old panel benefits from inspection. Our electrical inspection tells you exactly where you stand.
