IEC C20 to C21 Extension

This 15 ft black extension cord adds reach between a rack PDU, UPS or server and an existing C20 power cord. The male C20 plug connects to the power source while the female C21 socket accepts the equipment cord. It is built for server, switch and AV gear deployments where standard IEC 60320 connectors are used.

20 A Continuous Rating

The cord uses 12 AWG three-conductor copper with an SJT jacket rated for 105 °C and 300 V. This construction supports a continuous 20 A load at 250 V, matching the limit of a 20 A branch circuit. Thinner gauges such as 18 AWG, 16 AWG or 14 AWG are rated for lower currents and would not meet this requirement.

Heavy-Duty Headroom

The 12 AWG gauge comfortably handles heavy-duty 20 A equipment in data-centre and rack environments. It is not intended for loads that exceed 20 A or for applications requiring a higher ampacity cable. Buyers needing more current capacity will require a larger conductor size.

Questions about this item

Which length of this C20-to-C21 extension cord should I choose?

This model is supplied as a single 15 ft length; select it when you need that exact reach between your PDU or UPS and the server or switch power inlet.

What does the 20A / 250V rating mean once the cord is installed in a rack?

It certifies the 12 AWG SJT cable and IEC 60320 C20/C21 connectors to carry up to 20 A at 250 V continuously, matching heavy-duty server and PDU loads.

What interface standard do the C20 and C21 connectors follow and what does it cap in practice?

Both ends conform to IEC 60320, so the cord plugs directly into standard rack PDUs, UPS outlets and server power supplies without adapters.
