Electrical & Panel Upgrade Cost in South Carolina (2026)

Panel upgrades and rewires in South Carolina typically run $2,000–$4,800 for a 200A service panel upgrade, with the 2020 NEC as the adopted enforcement basis. Service entrance design assumes a 200A minimum on new residential construction. Charleston, Hilton Head, and Myrtle Beach Atlantic salt-haze deposition corrodes outdoor service equipment within 5-7 years, mandating stainless mounting hardware and NEMA 4X meter sockets on shoreline upgrades — and the Lowcountry hurricane wind exposure across Beaufort, Charleston, and Horry counties drives reinforced weatherheads and category-rated service-mast bracing on every coastal panel upgrade.

How electrical and panel upgrade costs vary in South Carolina

State-specific code or insurance rule: South Carolina SC Code §40-59 places residential electrical work under the Residential Builders Commission rather than a freestanding electrical board — Residential Specialty Contractor SP-RBE (Electrical) is the credential required to bid and execute single-family panel upgrades and rewires, and the Commission also requires the Residential Builder's General Contractor credential on any project where electrical is bundled with structural work.
