North American (NEMA) Power Cords & Cord Sets
Interpower makes power connections for customers in North America and around the world. Within the electrical product design you are creating, you need a way to connect to the power source—Interpower is the premier supplier of power system components worldwide.
The National Electrical Manufacturers Association (NEMA) has a variety of standards for electrical manufacturers. This is so that consistency and safety can be achieved. A numbering system has been created to standardize the description and rating of NEMA plug and socket patterns.
The NEMA pattern and numbering system consists of four main identifiers. The first identifier can be blank or have the letter “L” which determines whether it is a straight or locking blade device. The second identifier is a number which indicates the voltage rating. The third identifier is a number which identifies the amperage rating. The fourth identifier is a letter which indicates if it is a plug, P, or a receptacle/outlet, R. See the NEMA Nomenclature Guide and the North American Non-locking NEMA Configurations Chart for more details.
Interpower offers a wide variety of NEMA 1-15, 5-15, 5-20, 6-15, 6-20, and angled 5-15 power cords and cord sets for North American markets. Also offered are North American hospital-grade products which meet UL and CSA standards and carry the green dot.
