The P041-014 30-amp Heavy-Duty Power Extension Cord features a NEMA L6-30P plug on one end and a NEMA L6-30R receptacle on the other. Both molded connectors twist and lock into place to prevent accidental disconnection via jostling or other impact. This heavy-duty extension cord allows you to extend the length of your existing power cord by 14 feet, or you can use it as a replacement for an old or lost power cord. It is recommended as an ideal alternative to the IBM 6654 cord for extending the power cord on a PDU or UPS system with a locking L6-30P plug. The 14-foot 10 AWG cord is rated for 250V and 30A and is tested to ANSI/UL 62 and 817 and CAN/CSA C22.2 no. 21 and 49 standards. Durable SJT jacket is sure to last a long time.
