The NEMA High Performance Wire and Cable Section develops technical standards and guidelines in four areas:
- Premise wiring
The section also works to influence government affairs and trade issues, and has the capability to collect market statistics and develop marketing programs along industry product lines.
Specific technical activities include:
- EAW– Electronic Appliance Wires - NEMA WC 73
- Aerospace– Maintains a number of NEMA Standards amongst each the most popular are HP 3 and HP 4, WC 27500. The Committee is also looking to transport other mil specs into voluntary NEMA Standards.
- Premise– ANSI/NEMA WC 66/ICEAS-116-732 – Standard For Category 6 And 6A, 100 Ohm, Individually Unshielded Twisted Pairs, Indoor Cables (With Or Without An Overall Shield) For Use In LAN Communication Wiring Systems
- Shipboard– NEMA is working with NAVSEA to update documents that eventually will be transferred to NEMA as voluntary standards.
The Section maintains a liaison with American National Standards Institute (ANSI), American Society of Testing Materials (ASTM), Building Industry Consulting Services Inc. (BICSI), Council for Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA), Canadian Standards Association (CSA), Defense Industry Supply Center, Naval Air Warfare Center, Naval Air Sea Command, Society Aeronautical Engineers, Telecommunications Industry Association and UL.
- Wires and cables, produced to both domestic and international standards and specifications, which are used primarily with devices which produce, transmit, receive, detect, distribute, control, record, or modify electrical signals and power.
- Specifically included are insulated signal and communications wire and cable, including voice and data types used for internal premises wiring, and such products as coaxial cable, microphone cable, hookup wire, appliance wiring material, multiconductor electronic cable, flat cable, motor lead wire, power-limited circuit cable, CATV drop and trunk lines, thermocouple wire, shipboard, airframe, automotive, and transit wire and cable.
- Excluded are exterior telephone (distribution) cables and other wire and cable types, which are specifically included in the scope of any other NEMA product section.

Standards play a vital part in the design, production, and distribution of products destined for both national and international commerce. 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 purchaser in selecting and obtaining the proper product for his particular need.
NEMA devotes much of its time, effort, and resources to voluntary standardization activities. Many NEMA standards are approved as American National Standards under the procedures of the American National Standards Institute.
- The High Performance Wire and Cable section technical activity is performed by 4 technical committees:
- Aerospace Wires and Cables
- Shipboard Wires and Cables
- Electronic Appliance Wires (EAW)
- Premise Wires and Cables – communication cables.
The meetings are attended by a substantial number of invited guests from the major jacket materials and core cable industries as well as NAVY representatives and large military contractors. For the commercial oriented activities of the last two committees National Recognized Testing Laboratories representatives attend meetings regularly.
- Standards the section is responsible for, by technical committee, include:
Develops and maintains voluntary NEMA Standards that evolved from military specs or were developed at the military requests. Relevant standards in the Committee purview are:
- WC 27500 ANSI/NEMA Standard for Aerospace and Industrial Electrical Cable

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.
Through NEMA, member companies are able to develop and implement tailored, industry-specific market and statistical programs that benefit participating companies. Reports may include:
- Product orders and sales
- Market forecasting
- Shipments by trading areas
- Channels of distribution
- Financial and operating ratios
- Wages and benefits
- Foreign trade
The association also conducts economic analyses on the impact of legislation and regulations on member products, and monitors and reports on key industry market indicators. All programs comply with NEMA statistical confidentiality policies. For more information, please see Business & Economy.
Membership in NEMA is open to any firm actively engaged in the manufacture in North America of a product within the NEMA scope and for sale in the open market. Membership of foreign firms is subject to product section policies and NEMA Board of Governors approval.
