PLUG 20 AMP NEMA 5-20

NEMA connectors are power plugs and receptacles used for AC mains electricity in North America and other countries that use the standards set by the US National Electrical Manufacturers Association. NEMA wiring devices are made in current ratings from 15 to 60 amperes (A), with voltage ratings from 125 to 600 volts (V). Different combinations of contact blade widths, shapes, orientations, and dimensions create non-interchangeable connectors that are unique for each combination of voltage, electric current carrying capacity, & grounding system. The 5-15P and 5-20P and the 5-15R and 5-20R are by far the most common electrical plug and receptacle combinations in North America.

A plug is an item that (1) provides a fitted closure for an opening designed to ensure a tight seal such as for a sink or a bottle, or for a hole or a space (2) completes an electrical connection. The plug may be removable (as for portable equipment), require a tool for assembly and removal, or serve as a permanent electrical joint between two points.
