8 ft NEMA 6-20P to C19 power cord

This 8 ft extension cord connects a NEMA 6-20P plug to an IEC C19 connector for 250 V equipment such as servers, PDUs and UPS units. It is built with 12 AWG SJT jacketed copper conductors rated for 20 A and 105 °C. The fully moulded, grounded design includes strain relief for durable data-centre use. UL and CSA certified, RoHS compliant.

Installation and common issues

Plug the 6-20P end into a matching 6-20R receptacle and the C19 end into the device C20 inlet; no tools are required. Ensure the outlet circuit is wired for 208/240 V and 20 A before connecting. The only frequent issue is attempting to use the cord on a 120 V or lower-amperage circuit, which the connectors physically prevent but installers sometimes overlook.

20 A 250 V rating decides fit

The cord carries a 20 A, 250 V rating on 12 AWG conductors with a 300 V insulation rating. This single specification determines whether the cord matches the load and supply voltage of the target equipment. Buyers needing a lower current rating, a different plug type or a 120 V cord will find this model unsuitable.

Questions about this item

How do I verify the cord is delivering 20 A at 250 V after I plug it in?

Check that the NEMA 6-20P seats fully in the 6-20R receptacle and the C19 locks onto the C20 inlet; the molded strain reliefs should sit flush with no gap, and connected equipment should power on without tripping the circuit breaker.

What comes in the box and is anything else required?

The package contains the single 8 ft 12 AWG SJT cord with a NEMA 6-20P plug on one end and an IEC 320 C19 connector on the other; no additional cables or adapters are needed if your outlet is 6-20R and your device has a C20 inlet.

Which Cable Leader model should I choose for a 208/240 V server rack?

Select the PW158-1208 when you need an 8 ft, 12 AWG, 20 A, 250 V cord with NEMA 6-20P to C19 ends; it is UL Listed, CSA certified (file E210037) and RoHS compliant for data-centre use.
