Expert Electrical Panel Upgrades in Milwaukee & Waukesha County

• Complete service upgrade from 100-amp to 200-amp capacity to handle modern electrical loads
• Coordination with We Energies for meter upgrades and service disconnect installation
• New weather head and service entrance cable sized for increased capacity
• Panel relocation options when existing panels are in inconvenient or unsafe locations
• Perfect preparation for adding EV chargers, solar systems, or central air conditioning

This is the upgrade we recommend most often for Milwaukee homes built before 1980. Your 100-amp service was fine when installed, but today's homes run more simultaneously—central air, multiple computers, kitchen appliances, charging devices. Upgrading to 200 amps gives you the capacity you need without worrying about tripping breakers.

• Complete replacement of screw-in fuse panels common in pre-1960s Milwaukee homes
• Modern circuit breaker panels that reset with a switch instead of requiring fuse replacement
• AFCI and GFCI protection that wasn't available when your fuse box was installed
• Elimination of dangerous practices like oversized fuses or penny-behind-the-fuse workarounds
• Often required by insurance companies for older Milwaukee properties

If you're still buying fuses at the hardware store, it's time for an upgrade. Circuit breakers are safer, more convenient, and give you better protection against electrical fires. Many insurance companies won't even cover homes with active fuse boxes anymore, especially the old screw-in type.

• Replacement of Federal Pacific, Zinsco, and other panels with known safety issues
• Upgrades from outdated split-bus panels to modern single-main-breaker designs
• Addition of whole-home surge protection during panel replacement
• Proper panel labeling and circuit documentation for future work
• Correction of amateur work, double-taps, and other code violations found during inspections

Not all panel upgrades are about adding capacity—sometimes you just need to replace an unsafe panel with a modern equivalent. Federal Pacific panels are notorious for breakers that don't trip when they should. We see these regularly in Milwaukee homes from the 1960s-80s, and they're worth replacing even if you're not increasing your service size.

• 300-amp or 400-amp service installations for homes over 4,000 square feet
• Support for multiple high-draw systems running simultaneously (HVAC, pool equipment, EV charging, workshop tools)
• Dual-panel configurations with main panel and coordinated subpanels
• Designed for homes with geothermal systems, multiple heat pumps, or extensive smart home automation
• Often required for new construction or significant additions to existing Milwaukee properties

Most residential homes don't need 300 or 400 amps, but larger properties sometimes do—especially if you're adding solar production, multiple EV chargers, a detached heated garage, and running commercial-grade kitchen equipment. We'll do a proper load calculation to determine if you actually need this level of service or if a 200-amp upgrade will suffice.

• Pre-wiring for automatic transfer switches during panel replacement
• Load calculations that account for both everyday use and backup power requirements
• Generator-ready subpanel configurations for homes planning future installations
• Coordination with generator systems for seamless integration
• Panel capacity upgrades to support both household loads and generator connectivity

Many Milwaukee homeowners upgrade their panel specifically to add a generator later. We'll future-proof your installation so you're not paying twice when you're ready for backup power. If you're already planning a generator, we can coordinate the panel work with the transfer switch installation to save time and minimize disruption.
