What Drives Price
Electrical service pricing hinges on distance from utility drop, conduit routing, and panel type. Key drivers include line length to the panel, whether a new meter socket is needed, and the presence of any old wiring that requires replacement. Assumptions: 100 amp main panel, standard residential lot.
Regional Price Differences
Prices vary by region due to labor rates and permit costs. In three typical U.S. markets, a 100 amp upgrade can differ by a considerable margin:
- Urban Northeast: higher labor and permit fees; average range $4,000–$8,000
- Suburban Midwest: mid-range pricing; average range $3,200–$6,000
- Rural Southwest: lower labor costs; average range $2,800–$5,000
Labor, Hours & Rates
Projected crew hours typically run 8–24 hours depending on site conditions and whether upgrades require panel relocation or wiring enhancements. A common breakdown is 4–10 hours for materials prep and 4–14 hours for on-site installation. data-formula=”labor_hours × hourly_rate”> Price sensitivity is highest when long trenching or custom meter relocation is involved.
