Extends C20 to C21 Connections

This 8 ft power extension cord adds reach between a rack PDU, UPS or server and an existing C20/C21 power cord. The male IEC 60320 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 installations that need extra length without an adapter.

Heavy-Duty 12 AWG Construction

The cord uses 12 AWG SJT-jacketed three-conductor copper rated for 20 A at 250 V and a 105 °C / 300 V cable rating. This gauge supports continuous heavy-duty loads up to 20 A, unlike lighter 14 AWG or 16 AWG cables that are limited to 15 A or 13 A respectively. The grounded construction maintains safe power delivery under sustained server and data-center demand.

UL Listed Safety and Thermal Rating

The assembly carries UL Listing and CSA certification (file E210037) plus RoHS compliance, confirming it meets recognised safety standards for continuous operation. The SJT jacket is rated to 105 °C, so the cable handles the heat generated by 20 A loads without degrading. The black jacket also helps identify circuits and phases at a glance in dense rack environments.

Questions about this item

Does the 12 AWG SJT cable stay cool when carrying a full 20 A load all day?

The 12 AWG SJT construction is rated 105 °C and 300 V, so it handles continuous 20 A / 250 V server loads without overheating.

My server PSU has a C14 inlet — will this C21 female end fit it?

No, the female end is an IEC 60320 C21 socket; it only accepts a C20 plug, not a C14 inlet.

Can I daisy-chain this cord after an older 14 AWG C20 cable running 15 A gear?

Yes — the 12 AWG 20 A rating exceeds the 14 AWG 15 A limit, so the extension will not become the bottleneck.
