Safeopedia explains Electric Receptacles
All receptacles have a NEMA (National Electrical Manufacturers Association) number.
NEMA designations are used to prevent the wrong combination of electrical systems from being connected together. This eliminates potentially hazardous conditions.The rating of every electrical receptacle, the size of the wire used to feed the outlet, and the breaker must all be matched.
The NEMA (National Electrical Manufacturers’ Association) configuration and designation specifies that sockets differ in voltage and current rating, shape, size and type of connectors. Each country sets its own standard for receptacles, some of which are listed in the IEC technical report TR 60083.
