NEMA for Industrial Heaters
The National Electrical Manufacturers Association, also known as NEMA, is one of the most prestigious and preferred trade associations for electrical product manufacturers. Member companies manufacture products that are used in conjunction with the generation, distribution, transmission, use, control and storage of electricity. The products are used for medical, institutional, commercial, residential and industrial applications. NEMA standards deal with the manufacture, performance testing, application and rating of various electrical products. The terminal boxes used on industrial electric heaters are typically given a NEMA rating to insure it meets the requirements of the environment where the heater will be installed. NEMA defines the requirements for electrical enclosures under NEMA Standard Number 250.
