Cable Leader 3 ft NEMA 6-20P to C19 Power Cord

This 3 ft black power cord connects servers, PDUs and 250V equipment to a 208/240V outlet using a NEMA 6-20P plug and a C19 connector. It is built with 12 AWG SJT-jacketed three-conductor grounded copper rated for 20A at 250V and 105C. The fully moulded design provides strain relief and a true three-wire ground. It carries UL Listing and CSA certification (file E210037) plus RoHS compliance.

Practical limits of the 20A 250V rating

The cord supports a continuous 20A load at 250V on 208/240V circuits, making it suitable for heavy-duty equipment that draws up to 20A. Lighter gauges such as 18 AWG handle only 10A, 16 AWG up to 13A and 14 AWG up to 15A, so this 12 AWG cord is required when the connected device needs the full 20A capacity. The SJT jacket is rated to 300V and 105C, setting the thermal and voltage ceiling for safe operation.

Check your outlet and device connector before

Verify that your facility provides a NEMA 6-20R receptacle supplying 208V or 240V and that the equipment you are powering accepts a C19 inlet. The plug will not fit standard 5-15R or 5-20R outlets, and the C19 end will not mate with a C13 or C15 inlet. Ensure the circuit breaker and wiring are rated for 20A service to match the cord’s capacity.

Questions about this item

Why choose 12 AWG over 14 AWG or 16 AWG for this 3 ft cord?

12 AWG supports up to 20A at 250V for heavy-duty equipment; 14 AWG caps at 15A and 16 AWG at 13A, so 12 AWG is required when your server or PDU draws the full 20A circuit rating.

What does the 20A 250V rating mean once the cord is plugged into a 208/240V circuit?

It means the cord can continuously carry 20 amps at up to 250 volts on a 208/240V circuit, limited by the 12 AWG copper conductors and the NEMA 6-20P plug rating.

What does the NEMA 6-20P to C19 interface cap in practice?

The NEMA 6-20P plug caps the connection at 20A 250V on a 208/240V outlet; the C19 connector caps the device end at the same 20A 250V, so the whole assembly is limited to 20A.
