NEMA 5-20P

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.

NEMA L5-20R Twist-Lock

The NEMA L5-20R Twist-Lock Connector is rated up to 125VAC and 20A. This couples with the L5-20P and locks into place, eliminating nuisance disconnection. This makes this connector common in commercial and industrial settings where there is high traffic. This connector is found on our L5-20 Extension Cord Series, which is used to extend power from an existing L5-20R wall receptacle or connector to a certain location for convenience.
