Electrical Panel Upgrade · Wisconsin
A panel upgrade replaces your breaker panel, and often the service entrance, so the home can safely carry more load: an EV charger, heat pump, induction range or addition. It always needs a permit, and usually needs the utility to disconnect and reconnect power.
Cold winters and older Milwaukee housing drive heating-circuit and rewiring work.
Across the Midwest, homes deal with cold winters, severe thunderstorms and tornado season. Permit offices, utilities and housing stock differ by city, which affects how electrical panel upgrade is planned and scheduled. These local guides cover the Wisconsin cities where we have written specific notes.
Many Milwaukee homes still have fuse boxes or 60 amp services, and adding central air, a modern kitchen, an EV charger or a heat pump usually requires an upgrade. Duplexes typically have two services and two meters, so both may need work.
Utility: We Energies
Madison has strong interest in heat pumps, EV chargers and rooftop solar, and older isthmus homes often have 60 or 100 amp services that cannot carry them together. A cold-climate heat pump with electric backup heat adds a lot of winter load, so a load calculation matters.
Utility: Madison Gas and Electric (MGE)
1. Load calculation
The electrician sizes the service from your existing and planned loads.
2. Permit and utility coordination
The permit is pulled and the utility schedules disconnect and reconnect.
3. Install the panel and service parts
New panel, breakers, grounding and bonding, and service conductors or meter base if needed.
4. Inspection
The local inspector checks the work before or after power is restored, depending on the jurisdiction.
Electricians set their own prices; local permit fees and utility requirements add to these factors.
Permits come from the city or county where the home is. For example: Milwaukee: Electrical permits in Milwaukee come from the city's Department of Neighborhood Services; suburbs issue their own. Madison: Electrical permits in Madison come from the city's Building Inspection division; surrounding cities and villages issue their own.
Milwaukee: We Energies. Madison: Madison Gas and Electric (MGE).
If you have 100 amps or less and are adding an EV charger, heat pump or electric range, or your panel is a Federal Pacific, Zinsco or fuse box, ask an electrician for a load calculation.
Usually most of one working day, depending on the scope and how quickly the utility reconnects.
Yes, in essentially every US jurisdiction. The electrician pulls it and schedules the inspection.
