The NEMA 5-20R (T-Slot) is a 3 wire grounded connector rated up to 125VAC and 20A. The 5-20R T-Slot receptacles are often used when 20A circuits are installed due to flexibility of being downward compatible with the 5-15P. This connector is found on our 5-20 Extension cord Series, used commonly for extending power from a standard NEMA 5-20R wall receptacle to a given location for convenience.
