NEMA 5-20P

NEMA 5-20P

General Information:

The NEMA 5-20P is a 3 Wire grounded plug featuring two blades and one ground pin rated up to 125V AC and 20 Amps. The NEMA 5-20P is used in applications that require higher power draw such as large refrigerators, space heaters, large kitchen mixers, etc. The 5-20R T-Slot receptacle allows you to plug in either a 5-20P or a 5-15P plug, allowing greater flexibility. In modern home installations, 5-20R T-Slot receptacles are often used when 20A circuits are installed due to flexibility of being downward compatible with the 5-15P.
