Smarter Power Starts at the Panel — Upgrade with Confidence in Sherwood, WI.
Your electrical panel is the heart of your home's power system. If it's outdated, undersized, or failing, everything connected to it is at risk. SJA Electrical specializes in electrical panel upgrades, breaker box repairs, and complete panel replacements across Sherwood. From aging Federal Pacific panels to 100-amp services that can't meet modern demands, we deliver cost-effective solutions that protect your home and increase its value.
Frequent tripping means circuits are overloaded or a breaker is failing. We replace faulty breakers and can upgrade your panel capacity to meet your actual electrical demands.
These panels are known for failing to trip during overloads, creating a serious fire hazard. SJA Electrical provides Federal Pacific electrical panel replacement as a priority service.
Most homes built before 1980 have 100-amp service. Today's electrical loads often require 200 amps minimum. We handle the full 200 amp panel upgrade including service entrance work.
If your breaker panel is full, we can install a subpanel to add capacity — perfect for home additions, workshops, or EV charging stations.
Electric vehicles are quickly becoming mainstream — and so is the need for Level 2 EV charging at home. But before you can install a Level 2 EV charger, your electrical panel needs to be up to the task. Most EV chargers require a dedicated 240-volt, 50-amp circuit, which means your panel must have available capacity.
Homes with older 100-amp service or full breaker panels often can't support an EV charger without a panel upgrade first. A 200-amp panel upgrade not only accommodates your charger but also future-proofs your home for other high-draw appliances — from heat pumps to induction stoves.
At SJA Electrical, we routinely pair electrical panel upgrades with EV charger installation across Sherwood, WI. We handle the full scope: panel assessment, upgrade, permit, charger installation, and inspection. One company, one process. If you're planning to go electric, start by calling us for an honest panel assessment — it's the smartest first step you can take.
