Below is a list of NEMA enclosure types; these types are further defined in NEMA 250- Enclosures for Electrical Equipment. Each type specifies characteristics of an enclosure, but not, for example, a specific enclosure size. Note that higher numbers do not include the lower-numbered tests. For example, types 3, 4 and 6 are intended for outdoor ...
NEMA 5-15P plug and NEMA 5-15R receptacle (different scales, blade spacing is 0.5 inches (12.7 mm) for both.) Each receptacle also accepts an ungrounded plug, whether polarized or unpolarized. Typical 5-15R residential receptacle 5-20R T-slot receptacle mounted with the hole for the ground pin at the top. The neutral connection is the wider T ...
NEMA (National Electrical Manufacturers Association) contactors and motor starters are rated by sizes. These sizes are grouped by rated current and power. [1] [2]
NEMA 1-15 polarised plug NEMA 1-15 unpolarised plug. NEMA-1 plugs have two parallel blades and are rated 15 A at 125 volts. They provide no ground connection but will fit into a grounding NEMA 5-15 receptacle. Early versions were not polarised, but most plugs are polarised today via a wider neutral blade.
Polycarbonate, glass-reinforced, and fiberglass boxes are used where stronger cabinets are required, and may additionally have a gasket to exclude dust and moisture. Metal cabinets may meet the conductivity requirements for electrical safety bonding and shielding of enclosed equipment from electromagnetic interference.

NEMA contact ratings are how much current at a rated voltage a relay or other pilot device can switch. The current rating of smaller NEMA contactors or their auxiliaries are defined by NEMA ICS 5: Industrial Control and Systems, Control Circuit and Pilot Devices [1] standard. The nomenclature is a letter followed by a three-digit number, the ...
The National Electrical Manufacturers Association (NEMA) [5] is the largest trade association of electrical equipment manufacturers in the United States. [6] Founded in 1926, it advocates for the industry and publishes standards for electrical products. Notably, the form of US household electrical outlets and plugs is specified by NEMA.
