About Black Extension Cable NEMA L6-20P to NEMA L6-20R 20A 250V
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.

L6-20 and L6-30 connectors are commonly found on in-rack power distribution units in applications where the main supply voltage is greater than 120 V. The locking capability and high power output also makes these connectors common in industrial settings for powering large equipment.
