Data-centre power jumper

This Nippon Labs cable bridges an IEC-60320-C20 plug to an IEC-60320-C21 receptacle using 12 AWG UL SJT conductors rated for 20 A at 250 V. The fully moulded black jacket measures four feet and carries UL and cUL listings plus RoHS and REACH compliance. It is built to extend or replace a power link between a server or network device and a PDU or UPS in a rack environment.

Rack installers needing a C20-to-C21 link

Technicians who must connect a C21 inlet on a server, switch or storage unit to a C20 outlet on a power strip or UPS will find the correct pinout and current rating here. The four-foot length suits adjacent rack units but leaves no slack for longer runs between cabinets. Installers who need a different connector pairing or a longer reach should select another cable.

Connector pair C20 to C21

The sole specification that determines fit is the IEC-60320-C20 plug on one end and the IEC-60320-C21 receptacle on the other. Only equipment presenting those exact inlet and outlet types can use this jumper.

Questions about this item

Do I need a PDU or UPS with a C20 inlet to plug the C20 end into?

Yes. The cord's C20 connector is designed to mate with a C20 inlet on a PDU or UPS, so the power source must provide that specific receptacle.

Will the 12 AWG conductors and 20 A rating safely carry the load from an older server that draws near the 20 A limit?

The cable uses UL SJT 12 AWG x 3C conductors rated for 20 A at 250 V, matching the maximum draw of equipment that uses a C21 inlet, so it will handle the load without derating.

How can I verify the cord is seated correctly after connecting the C21 end to my server and the C20 end to the PDU?

Both IEC 60320 connectors are keyed and fully molded; a firm, flush fit with no visible gap at either end confirms proper engagement and electrical continuity.
