About this product
Running a server, UPS, or rack PDU on a dedicated 20 amp 120V circuit with a NEMA L5-20R twist-lock receptacle, and the straight-blade cord in the box will not fit? This Cable Leader NEMA L5-20P to IEC C19 power cord locks into the L5-20R outlet with a quarter turn and feeds any device with a C20 inlet, rated 20A 125V so a fully loaded rack server or 2U UPS runs on one cord with no adapter. Built with 12 AWG three-conductor copper wire, a 105C SJT jacket, and fully molded strain-relief ends for racks and network closets. Compatible with any device using an IEC C20 inlet on a 120V 20A supply, including rack servers, UPS units, rack PDUs with a C20 input, network switches, storage arrays, and pro audio amplifiers; it does not fit 5-15R or 5-20R straight-blade wall outlets, 250V L6-20R receptacles, or C14 inlets. UL Listed, RoHS and REACH compliant. Best for: locking 120V 20A power to server, UPS, PDU, and network gear from an L5-20R outlet. Not for: straight-blade wall outlets, 250V circuits, C13/C14 equipment, or loads above 20A.

6'Lock Power to Rack Gear on a 20A L5-20R Circuit
A straight-blade plug can vibrate or get bumped loose behind a rack; a NEMA L5-20P twist-lock plug turns a quarter turn and stays seated until you release it. This cord runs from a 20 amp 120V L5-20R receptacle to any device with an IEC C20 inlet: rack servers with high-output power supplies, 2U and 3U UPS units, rack PDUs with a C20 input, core network switches, and storage arrays. Rated 20A 125V for the full circuit capacity.
20A 125V, 12 AWG Copper - Full 20 Amp Rating, No Hot Spots
A 14 AWG cord pushed to 20A on a long run warms up and drops voltage under sustained load; this cord uses 12 gauge (12 AWG) three-conductor copper sized for the full 20 amp rating with margin to spare. The NEMA L5-20P plug is the NEMA L5-20 locking standard for 20A 125V branch circuits, and the IEC C19 end meets the IEC 60320 spec for C20 inlets. 105C SJT jacket, UL Listed, RoHS and REACH compliant.
C20 Inlet Compatibility - Not for Straight-Blade Outlets
Works with any 120V device that has an IEC C20 power inlet: rack servers, UPS units, rack PDUs with C20 input, network switches, storage arrays, pro audio amplifiers. Quick check: Outlet is a NEMA L5-20R twist-lock - Yes; Device inlet is C20 (fits C19) - Yes; Outlet is a standard 5-15R or 5-20R straight-blade - No; Outlet is a 250V L6-20R or device inlet is C14 - No. For a C14 inlet, use a NEMA 5-15P to C13 cord instead.
Heavy-Duty 12 AWG SJT - Fully Molded Twist-Lock Ends
Three 12 AWG copper conductors inside a 105C-rated SJT jacket that stays flexible enough to route through rack rails and cable managers without kinking. Both the L5-20P locking plug and the C19 connector are fully molded with integrated strain relief, so the cord survives repeated locking and unlocking and being pulled through raised-floor runs. Black jacket blends into rack and data center wiring.
Sample-Tested Production - Cable Leader Direct Support
Each cord is sample-tested during production for continuity, polarity, and current rating. Manufactured to RoHS environmental standards (lead, mercury, and cadmium-free). If your cord arrives defective or stops working in normal use, Cable Leader handles replacement requests directly - no manufacturer redirects.

Running a server, UPS, or rack PDU on a dedicated 20 amp 120V circuit with a NEMA L5-20R twist-lock receptacle, and the straight-blade cord in the box will not fit? This Cable Leader NEMA L5-20P to IEC C19 power cord locks into the L5-20R outlet with a quarter turn and feeds any device with a C20 inlet, rated 20A 125V so a fully loaded rack server or 2U UPS runs on one cord with no adapter. Built with 12 AWG three-conductor copper wire, a 105C SJT jacket, and fully molded strain-relief ends for racks and network closets. Compatible with any device using an IEC C20 inlet on a 120V 20A supply, including rack servers, UPS units, rack PDUs with a C20 input, network switches, storage arrays, and pro audio amplifiers; it does not fit 5-15R or 5-20R straight-blade wall outlets, 250V L6-20R receptacles, or C14 inlets. UL Listed, RoHS and REACH compliant. Best for: locking 120V 20A power to server, UPS, PDU, and network gear from an L5-20R outlet. Not for: straight-blade wall outlets, 250V circuits, C13/C14 equipment, or loads above 20A.
Need to run a server, UPS, or rack PDU with an IEC C20 inlet from a 208V or 240V circuit with a NEMA 6-20 outlet? This Cable Leader NEMA 6-20P to IEC C19 power cord plugs into a 20 amp 6-20R receptacle and carries the full 20A 250V rating end to end, because the 6-20P plug, the 12 AWG conductors, and the C19 connector are all rated for 20 amps. Built with 12 gauge three-conductor cable in a black SJT jacket, with fully molded plugs and strain relief at both ends. Compatible with any device using an IEC C20 inlet on a 208V, 220V, or 240V supply, including servers, UPS units, rack PDUs with C20 input, high-power network switches, and ASIC miners; for loads that run around the clock, keep continuous draw at 16A or less. UL Listed and RoHS compliant. Best for: 208V/240V data center, server rack, and equipment power from a NEMA 6-20R outlet. Not for: 120V household outlets, NEMA 6-15R outlets, twist-lock L6-20 receptacles, or devices with a C14 inlet.
Need to power a UPS, rack PDU, or server with a C20 inlet from a standard wall outlet? This Cable Leader power cord pairs a NEMA 5-15P 3-prong grounded wall plug with an IEC 60320 C19 connector, delivering wall-outlet power directly to higher-power equipment without a PDU-to-device jumper. It is built from 14 AWG, 3-conductor copper wire with a flame-retardant VW-1 SJT jacket and fully molded ends, rated 15A at 125V for indoor use, and the cordset is UL Listed. The C19 connector fits the C20 inlets commonly found on rack PDUs, larger UPS units, servers, and core switches; it is larger than the common C13 and will not fit C14 inlets, and the 5-15P plug limits the cordset to 15A even though some C19 hardware exists in 20A versions. Best for: powering a C20-inlet UPS, PDU, or server from a standard North American wall outlet within 15A/125V. Not for: C13/C14 devices, 20A applications, 250V circuits, or outdoor use.
Need to power a server, UPS, or high-wattage workstation from a 208V or 240V circuit with a 20 amp NEMA 6-20R outlet, but the equipment only shipped with a standard 120V cord? This Cable Leader NEMA 6-20P to IEC C13 power cord connects any device with a C14 inlet directly to a 6-20R receptacle. The plug matches the 20A outlet, while the C13 end sets the cord rating at 15A 250V, so the device must draw 15 amps or less. Built with 14 AWG three-conductor copper wire, a 105C SJT jacket, and fully molded plugs with strain relief at both ends. Compatible with any device using an IEC C14 inlet on a 208V, 220V, or 240V supply, including servers, UPS units, rack PDUs with C14 input, network switches, and 240V workstations; it does not fit 120V wall outlets, NEMA 6-15R outlets, C20 inlets, or twist-lock L6 receptacles. UL Listed, RoHS and REACH compliant. Best for: 208V/240V rack and workstation power from a NEMA 6-20R outlet. Not for: 120V household outlets, 6-15R outlets, C19/C20 equipment, or loads above 15A.
