Extend an existing NEMA L5-30 power connection where the equipment inlet or power distribution point sits beyond the reach of the installed cord. This 6 ft locking extension cord places a NEMA L5-30 plug at the supply end and a NEMA L5-30 receptacle at the equipment end. The matching locking connector pattern helps retain the connection instead of relying on a straight-blade plug-and-socket fit. The cord is rated for 125 V and 30 A service and uses 10/3 AWG conductors. That combination aligns it with NEMA L5-30 equipment connections that need a grounded, 30 A locking extension between a source outlet and connected equipment. Verify that the source receptacle and equipment connection both use the NEMA L5-30 configuration before installation. NL530P-NL530R-6FENC provides a plug-to-receptacle extension rather than a connector conversion. Both ends retain the NEMA L5-30 locking format, making it suited to installations that need additional cable reach without changing the connector interface. The 6 ft length distinguishes it for short-distance power routing around racks, cabinets, power distribution equipment, and adjacent installed hardware. Its 10/3 AWG construction is specified for the stated 30 A electrical rating.
