About Black NEMA L6-20P to IEC 60320 C21 Adapter Power Cords
The NEMA L6-20P is a 3 wire grounded plug with a hot, hot and ground pin rated up to 250V and 20A. This plug can be locked into place on the matching receptacle which prevents nuisance disconnection. This plug is commonly found on in-rack power distribution units (PDU) where standard electrical service exceeds 125V, also in industrial settings to supply power to equipment or power tools.

The IEC 60320 C21 is a grounded 3 Wire connector rated up to 250V and 20 Amps. The C21 mates with a C22 or C20 inlet, and is commonly used in a jumper cable scenario in IT Installations providing power from a PDU to a server, router, switch or other computing device. The C21 is a HIGH TEMPERATURE version of the C19 connector, with a maximum pin temperature of 155°C instead of the standard 65°C ofa C19, and is typically used in high powered blade servers, large network routers, and other IT equipment that draws more power than a standard C13 can accommodate.

NEMA L6-20P
THE NEMA L6-20P is a 3 Wire 3 Blade grounded device with hot-hot-ground wiring and is rated up to 250V AC and 20 Amps. The NEMA L6-20P male plug mates with a NEMA L6-20R outlet/receptacle and securely locks by twisting into place. NEMA Twist Locking cables such as the L6-20P are used in applications where plugs can easily become disconnected, such as in factories, warehouses, production facilities, data centers, and other industrial applications. The L6-20P is typically used in conjunction with an IEC 60320 connector in a cordset to provide power to a device with a C20 or C22 inlet.
