NEMA is the largest U.S. trade organization representing manufacturers of products used in the generation, transmission, distribution, control, and end-use of electricity. Many of NEMA's 350+ standards have been approved as American National Standards or adopted by the federal government.

The National Electrical Manufacturers Association (NEMA) represents nearly 325 electrical equipment and medical imaging manufacturers that make safe, reliable, and efficient products and systems serving seven major markets: 

• Building Systems 

• Building Infrastructure 

• Lighting Systems 

• Industrial Products & Systems 

• Utility Products & Systems 

• Transportation Systems 

• Medical Imaging 

Our combined industries account for 360,000 American jobs in more than 7,000 facilities covering every state. These industries produce $106 billion in shipments and $36 billion in exports of electrical equipment and medical imaging technologies per year.

The NEMA methodology is the following: develop performance Standards and promote product interoperability to increase market demand while improving safety to mitigate risks.

As legislation and regulations are proposed, NEMA represents the collective interests of America's electrical manufacturers at every level of government, including local building codes, infrastructure funding, national energy laws, and international trade.
