Technical Activities

Standards play a vital part in the design, production, and distribution of products destined for both national and international comĀ­merce. Sound technical standards benefit the user, as well as the manufacturer, by improving safety, bringing about economies in product, eliminating misunderstandings between manufacturer and purchaser, and assisting the purĀ­chaser in selecting and obtaining the proper product for his particular need.

NEMA devotes much of its time, effort and resources to voluntary standardization activities. In 2017, the Section will publish a new NEMA TC 20 standard for "Low Hazard-High Temperature" RTRC and new editions of NEMA TCB 2, Selection and Installation Guidelines for Underground Nonmetallic Raceways, and NEMA TC 19, Nonmetallic Riser U-Type Guards.

Technical Committee members will collaborate with Canadian and Mexican industry counterparts on CANENA working groups to amend UL/CSA bi-national standards for ENT, LFNC and RTRC systems, which have transitioned to tri-national status to include ANCE.

In 2017, the Technical Committee will also develop NEMA Public Inputs for the 2020 National Electrical Code.

Government Affairs

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.
