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 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.
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.
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.
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.
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.
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.

EXCELLENT Based on 519 reviews Posted on Google Cubby’s Reviews Had my breaker replaced same day as request for service. they were in and out quickly, and the amount due was very fair. I am going to set up a future appointment to have the complete electrical box replaced. Jordan communicated effectively and efficiently. Update 10/15/2026: Travis from LEHMANN electrical and design completed installing 4 gfci outlets and installed a CSST bonding for my gas line. He communicated throughout the process and did outstanding work. Do yourself a favor and contact LEHMANN if you need any electrical work completed they’re honest, their pricing is fair,and they always give you an estimate before they start work.Posted on Google Linda Sumwalt 16 year old solar panel removal from a barn roof.Posted on Google Verneesha Banks The guys from Lehman were great!

From the moment he came out to give the estimate, he was very professional and able to answer our questions and provide the detail we needed to move forward. The installation itself was quick and of high-quality. I highly recommend Lehmann. Thank you!Posted on Google Renee Schultz Andy and Joe were so kind and professional. Andy offered fair pricing, and tried to repair my electrical issue using the most cost-effective solution. Would highly recommend Lehmann Electrical and Design!Posted on Google Sandy S I’d like to highly recommend Lehmann Electrical and Design. Recently my kitchen lost all power due to an overheating outlet. After calling several companies who were scheduling a week out for appointments, I called Lehmann and they came out the next day. Not only were their technicians, Alex and Travis, a pleasure to work with, they didn’t come in with a standard, by the book, approach. They thoughtfully considered and explained the options for fixing the problem, with safety being the number one priority. Lehmann will be my only choice for any future electrical needs.Posted on Google Krista Had a panel upgrade, fan installation, and some outlets relocated and added. I couldn’t be happier with Cavin and Team at Lehmann Electric! They were courteous, flexible, and knowledgeable; willing to answer any and all questions.

New Berlin Electrician FAQ
Quick answers to panel upgrades, permits, dual EV charging, solar ROI, and Industrial Park commercial work. Get clarity before you call.
How much do New Berlin electricians charge?
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. Backup generators (22-26 kW units with automatic transfer switches) cost $5,000-$15,000 installed. Every quote includes detailed NEC load calculations, materials itemization, City of New Berlin permit fees, labor hours, and timeline before approval. Commercial quotes for New Berlin Industrial Park tenants are scoped site-specifically with three-phase transformer coordination, tenant isolation breaker design, and As-Built drawing delivery.
Does New Berlin require electrical permits?
Yes. City of New Berlin permits are required for panel upgrades, circuits, EV chargers, solar, generators, and commercial buildouts. We pull permits, schedule inspections, and meet inspectors on site for first-pass approvals.
When should a larger New Berlin home move to a 320-amp service?
Consider 320-amp service when stacking heat pumps, dual EV chargers, electric range/dryer, solar, or batteries. Many newer New Berlin subdivisions hit that ceiling as they electrify. We run NEC load calcs and design upgrades for whole-household capacity without shuffling.
Can I install two Level 2 EV chargers at my New Berlin home?
Yes; it is one of the most common New Berlin requests due to two-EV households with larger garages. We install two independent 40-60 amp circuits, load-managed pairs, or 22 kW dedicated feeders based on existing service and charging patterns.
Does Lehmann Electrical cover New Berlin, Wisconsin?
Yes. Our Wauwatosa shop (12012 W Fairview Ave) reaches every New Berlin street via I-43, Moorland Road, or National Avenue, covering all neighborhoods and ZIP codes 53146 and 53151. We serve residential estates and Industrial Park commercial properties.
What electrical code governs New Berlin projects?
New Berlin enforces Wisconsin Administrative Code SPS 316 (aligned with NEC). City of New Berlin Community Development signs off on all work. We engineer circuits and grounding to pass first-visit inspections.
How long does a 320-amp service upgrade take on a New Berlin home?
200-amp swaps finish in one day; 320-400 amp upgrades take 1-2 days (meter base, service mast, split-bus, grounding). We coordinate We Energies, install equipment, and walk city inspectors through final checks.
Do New Berlin rooftops make good solar candidates?
Often yes; newer subdivisions support 10-20 kW arrays with strong ROI. We engineer systems to your We Energies usage, specify microinverters or optimizers, and pair solar with battery backup for storm-season outages.
What does a larger-home rewire cost in New Berlin?
Full rewires run $12,000-$28,000 based on square footage, circuits, and ceiling access. Newer subdivisions rarely need full rewires; scope is usually targeted at problem circuits, panel replacements, and code remediation.
Does Lehmann handle commercial work in the New Berlin Industrial Park?
Yes. Industrial Park is a regular service area; we handle tenant buildouts, three-phase feeders, machine circuits, LED retrofits, panel upgrades, and EV charging networks along Westridge, Rochester, and Lincoln Avenue. Projects include City of New Berlin permits and commissioning paperwork.
How do I verify a New Berlin electrician is licensed and insured?
Request Master Electrician license, liability/workers-comp insurance, BBB rating, and Google reviews. Lehmann: WI Master #1283316, Contractor #1492849, A+ BBB rating, 500+ verified 4.9-star reviews.
Which solar modules maximize ROI on a New Berlin roof?
We specify high-efficiency monocrystalline modules (REC, Silfab, Q CELLS, Maxeon; 430-470W) paired with Enphase IQ8 or SolarEdge optimizers for shading tolerance. Battery-ready inverters make future Powerwall or IQ Battery upgrades plug-and-play.
