Electrical Contractors and Other Wiring Installation Contractors

NAICS 238210 · Specialty Trade Contractors · SBA size standard: $19 million average annual receipts

Electrical contractors bid on projects, pull permits, schedule inspections, manage crews and materials, install wiring and fixtures, and handle service calls. For a firm that wires new homes, retrofits commercial buildings and responds to emergency repairs, the specialists turn leads into bids, bids into permitted schedules, material needs into orders, and completed work into invoices while tracking inspections and code requirements. The master electrician confirms all technical and code decisions.
