8ft NEMA L6-20P to IEC C19 PDU Power Cord, 12 AWG SJT Heavy Duty Locking, 20A/250V, UL Listed, Black

The NEMA L6-20P to IEC 60320 C19 power cord connects 250V, 20-amp equipment to a twist-lock branch circuit, pairing a locking L6-20P plug with a high-current C19 connector. Built on 12 AWG SJT cable and rated for 20A at 250V, it feeds high-draw hardware that exceeds the capacity of standard C13 and C14 cords. The locking plug keeps the connection secure in data centers, server rooms, and industrial sites, where an accidental disconnect on a power distribution unit can take an entire rack offline.

The IEC 60320 C19 connector terminates the device end and mates with the C20 inlet found on metered and switched PDUs, enterprise servers, and large UPS systems. Rated to 20A and 250V, the C19 carries substantially more current than the common C13, which makes it the standard interface for equipment that draws beyond the 10A C13 limit. Its molded PVC housing resists impact and strain relief failure on a busy rack floor.

The NEMA L6-20P plug is a 2-pole, 3-wire twist-lock connector rated for 20A at 250V. A short clockwise turn seats the curved blades into an L6-20R receptacle and locks them, so the cord will not vibrate loose under sustained load. This locking action suits raised-floor data centers, generator and transfer-switch feeds, and 250V dedicated circuits, where a straight-blade plug would risk pulling free and interrupting a voltage-sensitive load.

The cord is UL and cUL listed and CSA certified, built on SJT jacketed cable rated VW-1 flame retardant at 105°C and 300V. Molded connectors seal the conductor terminations against moisture and strain, and the assembly meets RoHS limits for restricted substances. UL file E204978 and CSA file 204790 document the wire and connector approvals, giving facility managers and electrical inspectors traceable references for compliance records.

Three 12 AWG pure copper conductors deliver a full 20A continuous at 250V, roughly 5,000 watts, with low voltage drop across longer rack runs and overhead trays. The flexible black SJT jacket routes cleanly through cable managers without kinking. Common deployments include feeding C20-inlet PDUs in server cabinets, powering 208 to 240V blade and rack servers, and connecting large UPS units and 250V laboratory or industrial machinery on dedicated branch circuits.

The black jacket provides a professional appearance and suits standard data center and enterprise rack deployments.

This cord fits any device with an IEC C20 inlet drawing up to 20A at 250V, including PDU and UPS models from Tripp Lite, APC, and similar manufacturers, and plugs into NEMA L6-20R twist-lock outlets on walls, generators, and transfer switches. It is offered in multiple lengths under the PW142-12XX family to match short in-rack jumpers or longer floor runs. For 30-amp circuits, select an L6-30P version instead; for 120V equipment, use a NEMA 5-15P to C19 cord.

FAQ

What is the difference between a NEMA L6-20P to C19 cord and a NEMA 5-15P to C19 cord?

The L6-20P version supplies 250V at 20A through a locking plug, while the 5-15P version supplies 120V at 15A through a standard straight blade. They use different voltages and pin configurations and are not interchangeable; choose the L6-20P cord only for 250V, 20-amp twist-lock circuits.

Is this cord compatible with my PDU or UPS?

Yes, if the unit has an IEC C20 power inlet rated for up to 20A at 250V, such as many metered and switched rack PDUs and large UPS systems. The C19 end plugs into the C20 inlet, and the L6-20P plug requires a matching NEMA L6-20R 250V twist-lock outlet on the supply side.

What wire gauge do I need for a 20A, 250V circuit?

Use 12 AWG conductors for a 20-amp, 250V load. This cord uses three 12 AWG (3.31 mm²) pure copper conductors in an SJT jacket, sized to carry a full 20A continuously while keeping voltage drop low on longer runs to the rack.

How do I connect the twist-lock plug?

Align the curved blades of the L6-20P plug with the slots of the L6-20R receptacle, push in, and turn clockwise about a quarter turn until it locks. Then seat the C19 connector firmly onto the equipment's C20 inlet. The locked plug resists vibration and accidental pull-out.

Which power cord is best, L6-20P or L6-30P, for my equipment?

Match the cord to the outlet and breaker on the circuit: choose L6-20P for a 20-amp, 250V twist-lock circuit and L6-30P for a 30-amp circuit. Using an L6-20P cord on equipment wired for 30A, or the reverse, will not fit the receptacle and is unsafe.
