12 AWG C20 to C21 8 ft power cord

This 12 AWG cord connects a C21 receptacle on a server or computer to a C20 inlet on a PDU or UPS in a data centre. It is rated for 20 A at 250 V and uses UL SJT three-conductor cable. The fully moulded construction and UL/cUL listings confirm compliance with safety standards. RoHS and REACH compliant materials are used throughout.

Thermals noise and power draw

The cord carries up to 20 A continuously at 250 V without active cooling or moving parts. Power dissipation is limited to resistive losses in the 12 AWG conductors under normal load. No fan noise or thermal management is required. The cable operates silently in rack or floor installations.

Replaces shorter or lighter cords

Use this jumper when an existing cord is too short to reach the PDU or UPS, or when a lower-gauge cable cannot handle the required current. The 8 ft length adds placement flexibility in racks. It is not suited for connections that demand a different connector type or a lower amperage rating.

Questions about this item

How do I install the C20-to-C21 cord, and which orientation mistake should I avoid?

Plug the C20 connector into the PDU or UPS outlet and the C21 connector into the server or device inlet; the keyed C21 socket only accepts the C20 plug one way, so do not force it if the ground pin does not align.

What maintenance or replacement will this 12 AWG SJT cord need over time?

Inspect the fully molded ends and jacket periodically for cracks, discoloration or loose retention clips; replace the cord if any damage appears or the connectors no longer latch securely.

What is the first limit reached when this cord runs at full 20 A load continuously?

The 12 AWG conductors are rated for 20 A at 250 V; sustained operation at that current makes conductor temperature the limiting factor, so ensure adequate airflow around the cable run.
