The Mission
The National Electrical Manufacturers Association (NEMA) is the definitive voice of the electrical manufacturing industry in the United States. Founded in 1926 and headquartered in Arlington, Virginia, NEMA represents over 300 member companies that manufacture the equipment used to generate, transmit, distribute, and control electricity. The impact of NEMA’s members is vast, representing roughly 1% of the U.S. gross domestic product and supporting 580,000 skilled jobs. From the massive transformers on the utility grid to the light switches in your home, NEMA members build the infrastructure of modern life.
Whether you are an electrical engineer specifying industrial enclosures, a procurement professional sourcing motors for a federal infrastructure project, or a utility leader planning for a 50% increase in electricity demand by 2050, NEMA provides the essential framework for your work. Through its standards, market intelligence, and policy advocacy, NEMA ensures that electrical systems are safe, reliable, and interoperable. By bridging the gap between manufacturers and policymakers, NEMA helps the electroindustry navigate trade frameworks, supply chain security, and the urgent requirements of grid modernization.
NEMA’s standards program is one of its most enduring contributions to global commerce. The association maintains a catalog of nearly 700 standards covering every imaginable category of electrical product. These documents are developed by technical experts who understand the nuances of how products are manufactured, installed, and maintained in the field. By establishing clear technical benchmarks, NACE ensures that a motor or connector from one manufacturer will work safely and effectively within a system built by another.
While NEMA standards are technically voluntary, they are a practical necessity for market access. They are frequently incorporated into building codes, procurement contracts, and regulatory frameworks worldwide. The most famous of these is the NEMA enclosure rating system, which defines the environmental protection levels for electrical cabinets. Whether a project requires protection against windblown dust, hose-directed water, or corrosive agents, NEMA standards provide the authoritative reference that engineers and contractors rely on to ensure equipment longevity and personnel safety.
NEMA operates at the intersection of technology, economics, and policy. Its work spans the development of standards for lighting systems, medical imaging through the MITA division, and power distribution equipment. Beyond technical documents, NEMA is a premier provider of market intelligence. Its annual “Guide to the Electroindustry” provides the deep economic analysis and shipments data that companies need to make strategic investment decisions. This data-driven approach allows NEMA to advocate effectively for the domestic manufacturing competitiveness of the U.S. electrical sector.
NEMA also leads the way in regulatory compliance and advocacy. The “Make It American” program is a critical resource for companies navigating the Build America Buy America (BABA) requirements for federally funded infrastructure projects. By providing certification support, NEMA helps manufacturers prove domestic content compliance. At the same time, NEMA’s policy teams engage with Washington to ensure that the U.S. grid is ready for the future. From electric vehicle charging infrastructure to energy storage, NEMA creates the standards and the policy environment needed for a smarter, more resilient electric future.
NEMA was formed in 1926 through the merger of the Electric Power Club and the Associated Manufacturers of Electrical Supplies. This union occurred during a transformative era of American electrification, when the industry realized that a fragmented market of incompatible parts was hindering growth. For a century, NEMA has provided the neutral forum where competitors come together to agree on the technical specifications that allow the industry to scale safely.
As NEMA approaches its centennial in 2026, its influence has become truly international. The U.S. electroindustry is the nation’s second-largest exporter of manufactured goods, and NEMA standards are used as the blueprint for electrical safety and performance in markets around the globe. By advocating for fair trade frameworks and supply chain security, NEMA ensures that American electrical expertise continues to set the standard for the global energy transition, supporting the deployment of smart grid technologies and renewable energy integration on a massive scale.
NEMA membership offers electrical manufacturers a seat at the table where the future of the industry is decided. Members gain a direct voice in the standards development process, allowing them to contribute technical expertise to the documents that will govern their product lines. This participation provides an “early look” at technical shifts and regulatory trends, giving member companies the lead time they need to innovate and maintain a competitive edge.
In addition to technical influence, members receive exclusive access to NEMA’s market intelligence and advocacy resources. This includes compliance support for federal infrastructure projects and access to the NEMA Academy for workforce training. For any manufacturer looking to navigate the complexities of the modern electrical market—from supply chain disruptions to new energy regulations—NEMA membership provides the community and the tools necessary for long-term strategic success.
The “skilled worker gap” is one of the greatest challenges facing the electroindustry. NEMA addresses this head-on by advocating for expanded apprenticeship programs and technical training pathways. A workforce of 580,000 people across 12,500 locations is the backbone of the industry, and NEMA is committed to ensuring that these professionals have the skills needed for the 21st-century grid.
Through the NEMA Academy and a vast library of application guides, the association provides essential learning resources for engineers and contractors. These materials cover emerging fields like distributed energy resources (DERs), energy storage systems, and smart grid integration.
By providing the educational foundation for these new technologies, NEMA ensures that the transition to a more electrified economy is supported by a workforce that is trained to the highest standards of safety and interoperability.
