Heavy-Duty C20-to-C21 Cord for Rack Gear

This 4 ft cable uses 12 AWG conductors and 20 A C20-to-C21 connectors rated to 250 V. It is built for switches, servers and other high-powered network devices that draw enough current to need a heavy-gauge link in a rack enclosure.

Replaces Thinner Cables That Overheat in Dense Racks

Standard cords with smaller wire gauges cannot handle the sustained 20 A loads common in blade servers or AI clusters. The jump is worth it when your equipment runs hot enough to push connector temperatures toward 105 °C and you need a cord that stays safe under that stress.

Verify Your Gear Uses C19 Inlets and Fits a 4 ft Run

Check that each device has a C19 power inlet and that the PDU or UPS presents a C20 outlet. Measure the rack path to confirm 1.2 m reaches without tension, and ensure the blue jacket meets any colour-coding rules your site enforces.

Questions about this item

What clearance does the 4 ft 12 AWG cord need behind a rack-mounted device?

The 4 ft (1.2 m) length is sized for typical rack-depth spacing; allow a few centimetres of bend radius behind the C21 inlet so the 12 AWG jacket does not kink.

Which way round do the C20 and C21 ends go when wiring a PDU to a server?

Plug the C20 end into the PDU or UPS outlet and the C21 end into the server or switch inlet; reversing them will not seat because the keyed notches are mirrored.

When should the blue jacket be inspected for heat damage in a 105 °C rated enclosure?

Check the jacket annually or after any thermal event; discolouration, stiffness or cracking near the C20/C21 mouldings means the cord has exceeded its 105 °C (221 °F) rating and must be replaced.
