Quick answer

Naugle's licensed Michigan electricians handle 100A → 200A service upgrades and Federal Pacific / Zinsco panel replacements across Lenawee County. We do a free load calc and only recommend the upgrade if your panel actually needs it — about half the homes we look at don't. Permit pulled, utility coordination with DTE or Consumers Energy, Square D / Eaton / Siemens panels installed. Call or text 517-423-3121.

When you need a panel upgrade

Common reasons: adding an EV charger, heat pump, or hot tub; running out of breaker slots; an old Federal Pacific or Zinsco panel (both known fire hazards now flagged by most insurers); a 100-amp panel feeding a 2,500+ sq ft home with electric range, dryer, and water heater; or frequent nuisance breaker trips that aren't a single bad circuit.

We do a free load calculation as part of the estimate and tell you whether you can add new loads to your existing panel or actually need a 200-amp upgrade. Honest answer either way — we don't sell upgrades to homes that don't need them.

What's involved in a 100A → 200A upgrade

Full service upgrade: new 200-amp main panel, new meter base (if required by code or utility), new service entrance cable, ground rod/bonding to current code, permit, utility disconnect/reconnect coordination, and inspection.

FAQ

Panel Upgrades questions, answered

Common signs: frequent breaker trips, lights dimming when the AC kicks on, only 100-amp service feeding a 2,500+ sq ft home, no room to add new circuits, an old Federal Pacific or Zinsco panel (both are known fire hazards), or planning to add an EV charger, heat pump, or hot tub. We do a free assessment.

How financing fits with your install

  • Same equipment options. Financing doesn't change what we install or how — only how you pay for it.
  • Multiple plan lengths. Short-term 0% APR promos through longer-term loans, so the payment fits the household budget.
  • Decision at the estimate. We bring the lender right to your kitchen table. Approval is typically a few minutes.
  • Stack with rebates. Financing works alongside any utility rebate or federal tax credit you qualify for — we file the paperwork.

Financing through third-party lenders. Terms and approval depend on credit qualification, loan product, and equipment.
