Sussex grew rapidly in the 1990s and 2000s, and most of its housing stock was built with modern electrical infrastructure — 200-amp service panels, copper branch circuit wiring, and GFCI protection in wet areas. The knob-and-tube wiring and Federal Pacific panels that characterize older Milwaukee suburbs are not a significant factor in Sussex. What Sussex homeowners face instead is the challenge of modern electrical load growth pushing against the limits of 1990s and 2000s panel designs.
EV chargers are the most common new electrical load request Burkhardt receives in Sussex. A Level 2 charger requires a dedicated 240V circuit drawing 30 to 50 amps — and in a home where two adults might both drive EVs, that could mean two such circuits. Combined with central AC, an electric clothes dryer, a home office, and possibly an air source heat pump, the total load on a 200-amp service may exceed comfortable operating capacity. Load calculation is essential before adding significant new electrical loads.

My Sussex home has a 200-amp panel from the late 1990s. Can I add two EV chargers without upgrading?
It depends on your current load. Two Level 2 EV charger circuits can draw 60 to 100 amps combined — a significant portion of a 200-amp service. Burkhardt calculates your total household load to determine whether you have sufficient capacity or whether a smart load management device or panel upgrade is the better solution.
What smart home circuits should I consider when upgrading electrical in my Sussex home?
Common additions include dedicated circuits for home theater and audio systems, low-voltage infrastructure for structured wiring panels, outdoor outlet circuits for landscape lighting and seasonal decorations, and pre-wired conduit for future EV or solar connections. Burkhardt's electricians plan for your current and future needs during any panel or circuit upgrade.
Does Burkhardt install whole-home surge protection in Sussex?
Yes. Whole-home surge protection at the panel level is a cost-effective way to protect electronics, appliances, and HVAC equipment from voltage spikes. Burkhardt installs service entrance surge protectors during panel upgrades and as a standalone upgrade to any existing panel. Call 414-206-3049.
