Building wire and cable is used in the construction of almost every commercial, industrial, and residential property in the world. Most commonly known as branch circuit wiring in homes and businesses, these products carry electrical current to all external uses of power in a building or dwelling.
The Building Wire and Cable Group and Dues Center develops technical standards and guidelines, influences government affairs and trade issues, collects market data, and develops marketing programs on its products.

For 2015, the Building Wire and Cable Technical Committee is engaged in the following activities:
1) In cooperation with their Canadian and Mexican counterparts, the development and maintenance of building wire standards and test procedures for use throughout North America, under the auspices of CANENA.
2) Amending to UL 83 and UL 44 to permit 600 V rated conductor Types to be rated 1000 V with the same insulation thickness when meeting specified electrical properties.
3) Consideration toward developing a NEMA Engineering Bulletin to address conduit fill when installing plexed wiring systems.
4) Pursuit of a harmonized print legend format for North America.
5) Interaction with UL wire and cable engineers on insulation and jacketing compound issues, follow-up procedures and administrative matters
6) Interaction with the outlet box and cable fittings industries as needed.
7) Impacting environmental issues critical to the industry.
Through NEMA, the section develops industry positions on legislative and regulatory initiatives that may affect member products, markets, and customers. NEMA's work has resulted in contributions to public policy development and in promoting competitiveness, technological progress, and public safety. On the Government Affairs homepage members can search for and e-mail federal representatives to convey opinions regarding energy policy or other issues related to the electroindustry.
NEMA Government Affairs provides specific services to its members and information in the areas of Environment, Health & Safety; Energy; and International Trade & Commerce.
