Electrical connectors are electro-mechanical devices that join electrical terminations to create an electrical circuit. Connector housings are usually made of molded plastic. Terminals are usually made of metal or other conductive materials.

Products include:

  • Connectors (clamp-type, metal-clad or armored, molded rubber, pressure, split-bolt, substation, and twist-on wire)
  • Electric power connectors
  • Ground rods and accessories
  • Installation tooling
  • Lightning protection systems
  • Overhead lines connectors
  • Pressure connectors
  • Underground distribution type cable connectors and accessories

NEMA meets the needs of Members, the industry, and users of their products through direct input in drafting Standards, promoting harmonization, and advocating for regulatory policies that drive the market.
