Panel Upgrades & Service Changes
Modernize your electrical panel for improved safety, capacity, and code compliance.
Why You Need This Service
Older electrical panels often can't handle the power demands of modern homes and businesses. Frequent circuit breaker trips, outdated fuse boxes, insufficient amperage for new appliances or equipment, or non-compliant panels are all signs you may need an upgrade. Panel upgrades and service changes not only improve safety and functionality but are often required for adding major appliances, home additions, or passing home inspections.
What's Included
Typical Project Scope
Panel upgrades typically involve replacing an outdated panel with a new, larger capacity panel and associated service entrance equipment. Service changes may also require upgrading the meter base and coordinating a temporary power outage with the utility company. The entire process usually takes 1-2 days, including permit processing, utility coordination, installation, and final inspection.

Frequently Asked Questions
How do I know if I need a panel upgrade?
Common signs include frequently tripping breakers, a fuse box instead of a breaker panel, a panel rated at 100 amps or less, visible corrosion or rust on the panel, or plans to add major appliances like an EV charger, hot tub, or central AC. If your home was built before 1990 and has never had a panel upgrade, it's worth having us assess it.
How long does a panel upgrade take?
Most panel upgrades are completed in one day. A straightforward 100A to 200A upgrade typically takes 6-8 hours. If the service entrance or meter base also needs replacement, or if utility coordination requires scheduling, the project may span two days.
Will I lose power during the panel upgrade?
Yes, power will need to be shut off during the panel swap, typically for 4-6 hours. We coordinate with We Energies or your local utility to schedule the disconnection. We recommend planning for the outage and can advise on how to prepare.
How much does a 200 amp panel upgrade cost in Wisconsin?
A 200 amp panel upgrade in Wisconsin typically costs between $2,000 and $4,000, depending on the complexity of the installation and whether the meter base or service entrance also needs to be replaced. We provide a detailed written estimate before beginning any work.
