NECA: National Electrical Contractors Association

NECA, the National Electrical Contractors Association, is the voice of the $130 billion industry responsible for bringing electrical power, lighting, and communications to buildings and communities across the United States. Established in 1901, the organization is dedicated to serving the management interests of the entire electrical contracting industry. NECA represents electrical contractors from firms of all sizes performing a range of services. While most NECA contractors qualify as small businesses, many large, multinational companies are also members of the association. Standards from NECA are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: [email protected] or 1-212-642-4980 or Request Proposal Price.
