Industry Definition & Overview
Electrical Contractors and Other Wiring Installation Contractors (NAICS 238210) encompasses establishments primarily engaged in installing and servicing electrical wiring and equipment per the U.S. Census Bureau[3]. Work performed includes new construction, additions, alterations, maintenance, and repairs. Activities include power distribution wiring, lighting system installation, fire alarm and security system wiring, data and telecommunications cabling, generator installation, and solar photovoltaic electrical interconnection. Contractors in this classification provide both labor and materials when performing electrical work.
Roughly 77,550 firms operate 79,292 establishments employing 909,447 workers with $62.7 billion in annual payroll per Census Bureau[4] economic survey data, making this the largest specialty trade classification by employment. Average hourly wages reach $41.29 per Bureau of Labor Statistics[5] data. National Electrical Contractors Association (NECA[6]) represents the electrical contracting industry through 119 local chapters. International Brotherhood of Electrical Workers (IBEW) trains over 50,000 apprentice electricians annually through the joint apprenticeship program. Electric vehicle charging infrastructure, solar energy interconnection, data center power distribution, and grid modernization represent current growth drivers.
Per the SBA Table of Size Standards[7], the size standard is $19 million in average annual receipts. National Electrical Code (NEC), published by the National Fire Protection Association (NFPA[8]), establishes electrical installation safety standards adopted by all U.S. jurisdictions. OSHA[9] electrical safety standards under 29 CFR 1926 Subpart K govern electrical construction safety, with arc flash exposure and electrocution prevention representing the most serious safety hazards. State and local electrical licensing requirements mandate journeyman and master electrician licenses for individuals performing electrical work, with contractor licensing required for firms. Electrical inspection by local building departments verifies NEC compliance at rough-in and final stages of construction.
