IEC C20 to C21 12 AWG Extension

This 10 ft heavy-duty cord extends an IEC 60320 C20 to C21 connection between a PDU, UPS or server and your existing cable. It uses 12 AWG SJT-jacketed copper rated 20A at 250V with a 105C, 300V insulation rating. The black jacket helps identify circuits in a rack. It is UL Listed and CSA certified (file 210037) and RoHS compliant.

Suits 20A rack equipment

Builders needing a 20A extension for server, switch or AV gear with C20/C21 connectors will use this cord. Buyers whose equipment uses a different IEC connector or a lower amperage inlet should look at another cable. Anyone needing a length other than 10 ft must choose a different SKU.

12 AWG 20A rating decides fit

The 12 AWG construction supports up to 20A continuous load at 250V, matching heavy-duty server and PDU requirements. Lighter 14, 16 or 18 AWG cords cannot carry this current safely. Verify your device draws 20A or less and uses C20/C21 before ordering.

Questions about this item

What current does the IEC 60320 C20 to C21 cord handle at 250 V?

The 12 AWG SJT cable is rated for 20 A at 250 V, suitable for heavy-duty server and PDU loads.

What clearance does the C20 plug and C21 socket need in a rack?

Standard IEC 60320 C20 and C21 connectors fit typical PDU and server inlets; allow space for the 10 ft SJT jacket bend radius.

How do you connect the extension without reversing ends?

Plug the male C20 into the PDU or UPS outlet first, then insert your device cord into the female C21 — reversing them leaves the live pins exposed.
