Our 4-Step New Berlin Electrical Process
Four-phase workflow: Scope, Engineer, Deploy, Commission. Delivers Master Electrician analysis, NEC calculations, Wisconsin SPS 316 compliance, panel schedules, and City permit coordination. Ensures transparent pricing, We Energies coordination, and commissioning for closings and insurance compliance.
Scope
Master Electrician visit: photographs service entrance, tests ground resistance, documents breaker ratings, captures We Energies meter, and calculates NEC loads for dual EV, heat pump, solar, and generators. Assesses code violations, safety hazards (cloth-insulation, Federal Pacific panels), and City of New Berlin/Wisconsin SPS 316 permitting.
Engineer
Engineered proposal: NEC load calculations, feeder sizing, Wisconsin SPS 316 compliance, panel schedule, itemized permit fees, labor estimates, timeline, We Energies coordination, and 12-month warranty. Includes site photos, equipment specs (Siemens, Square D, Tesla, Generac), design drawings, and ROI for solar and generators.
Deploy
Licensed crew executes work under City permit with We Energies coordination, installs copper/aluminum per NEC, rough-in and final inspections, continuity testing, and job cleanup. Typical timelines: 1-2 days for 200-amp swap, 2-5 days for 320-amp upgrade, 10-30 days for rewires or solar.
Commission
City of New Berlin permit, panel directory, equipment warranties, and 12-month labor warranty cover all circuits and installations. Solar: net metering coordination and tax credit documentation. EV: load management verification. Generators: 6-10 second failover and maintenance agreements. Commercial: As-Built drawings and landlord commissioning sign-off.
Electrical Challenges Unique to New Berlin
Larger New Berlin homes (2500-4500 sq ft) face simultaneous electrification demand from heat pumps, dual EV chargers, and solar on original 200-amp panels. Industrial Park tenants need three-phase upgrades. Both require Master Electrician load calculations and service upgrades.
200-Amp Panels Hitting Electrification Load Ceiling
200-amp panels overload with heat pumps, dual EV chargers, water heaters, and solar simultaneously. Upgrade to 320 or 400-amp service with NEC load calculations and We Energies coordination. Wisconsin Master Electrician designs for 40-50% headroom, allowing future heat pump water heaters, larger solar (15-25 kW), and batteries without panel shuffling.
Dual-EV Households Outpacing Single Circuits
One 40-amp charger cannot charge two EVs overnight. Install dual 40-60 amp circuits with load-management or specify 22 kW dedicated charger with failover. We engineer solutions based on panel capacity and We Energies demand charges.
Solar + Battery Retrofits Requiring Infrastructure Rework
Older string inverters cannot communicate with Tesla Powerwall or Enphase IQ Battery. Upgrade to hybrid inverters with battery management and critical-load subpanels. Our retrofits cost 30-40% less than full array replacement and ensure solar-battery optimization.
Larger Homes Face Amplified Outage Costs
Larger New Berlin estates risk spoiled food and frozen pipes during spring storms or winter outages. Install 22-26 kW Generac or Kohler standby with 6-10 second automatic failover for heating, wells, and internet. Annual commissioning ensures reliability.
New Berlin Industrial Park: Single-Phase Limits vs Three-Phase Demand
Industrial Park tenants need three-phase 208/480V for CNC mills, compressors, and fleet EV charging. Lehmann engineers transformer sizing, tenant-isolable breakers, building riser coordination, and Arc-Flash analysis per NFPA 70E, delivering As-Built commissioning for occupancy permits and insurance underwriting.
Home Automation Requires Structured Wiring and Isolated Circuits
Smart systems (Lutron, Control4, Leviton) need Category 6A cabling, 24V DC control, and isolated 120V circuits. Lehmann pre-wires Category 6A runs, control distribution, WiFi 6E mesh, enabling reliable scene control, voice integration, and future expansion without network headaches.

Residential service calls and diagnostics run $150-$500 depending on scope and visit duration. Panel upgrades from 200-amp to 320 or 400-amp service cost $3,500-$8,500 depending on meter base replacement, service drop upgrade coordination with We Energies utility, and split-bus or paralleled-main equipment. Single EV charger installations (Level 2, 40-60 amp circuits) run $800-$2,500 including circuit run, Tesla Wall Connector or NACS hardware, and permit coordination. Dual EV chargers (load-managed or independent circuits) cost $1,500-$4,000. Solar installations (10-20 kW systems with microinverters or optimizers) range $15,000-$35,000 before federal 30% Investment Tax Credit and state rebates.
