Signs You Need an Electrical Panel Upgrade

Many homes in Southeast Wisconsin were built with 60-amp or 100-amp electrical services, which were sufficient decades ago but are vastly underpowered for modern living. You should consider upgrading your electrical panel if you experience any of the following:

​

• Frequent Tripped Breakers: If you constantly reset circuit breakers when running the microwave and toaster simultaneously, your panel is overloaded.

• Flickering or Dimming Lights: Lights that dim when the AC or refrigerator kicks on indicate a lack of available amperage.

• Outdated Fuse Boxes: If your home still uses screw-in fuses rather than modern circuit breakers, upgrade immediately for safety and insurance purposes.

• Planning Major Additions: Adding a hot tub, remodeling a kitchen, or installing an EV charger typically requires a 200-amp service upgrade.

• Federal Pacific or Zinsco Panels: These brands have known safety defects and high failure rates. Replace them immediately to prevent fire hazards.

The 200-Amp Service Upgrade Process

Upgrading from a 100-amp to a 200-amp electrical service is a major project that requires a licensed master electrician. At Home and Business Electric, we handle the entire process safely and efficiently. We begin by pulling all necessary local permits in Waukesha County and coordinating directly with WE Energies to schedule the temporary power disconnect.

 

We then replace the exterior meter socket, install a new high-capacity grounding system, and mount a modern, high-quality breaker panel inside your home. All existing circuits are carefully labeled and reconnected to the new breakers, balanced to current National Electrical Code (NEC) standards. Finally, we arrange for the municipal electrical inspector to review the work.
