Purpose and fit

This power cord links a NEMA 6-20P outlet to a C19 inlet on servers, PDUs or other 250V equipment. It suits data-centre racks, network closets and industrial cabinets that run on 208/240V circuits and need a grounded, heavy-duty connection.

Load behaviour

The SJT-jacketed 12 AWG copper cable carries 20A continuously at 250V with a 105C / 300V insulation rating. Molded connectors and strain relief keep the three-wire grounded path secure during sustained high-current operation.

Deciding specification

The 12 AWG gauge is rated for 20A loads, unlike 14 AWG at 15A or 16 AWG at 13A. Buyers whose gear draws more than 15A need this gauge; those with lighter 10A-13A devices can use a thinner cord.

Questions about this item

Does the 12 AWG copper and SJT jacket run hot when the cord carries 20 A all day?

The 12 AWG 3-conductor copper is rated for 20 A at 250 V with a 105 °C / 300 V SJT jacket, so it stays within safe temperature limits under continuous full-load use.

My rack only has a NEMA 6-20R outlet — will the 6-20P plug on this cord fit directly?

Yes, the molded NEMA 6-20P plug is built for a 208/240 V 20 A receptacle, so it mates with a standard 6-20R outlet without an adapter.

I still use a server with a C19 inlet rated for 15 A — is the 20 A cord safe on that older unit?

The cord’s 20 A rating is its maximum capacity; the server will only draw the current it needs, so the heavier 12 AWG cable simply provides extra margin on a 15 A load.
