3ft IEC-60320 C14 to C19 Extension Power Cord 14AWG 15A/250V SJT, Black

The Cable Leader PW128-12XX is a heavy-duty IEC 60320 C14 to C19 power cord built to bridge a PDU C13 outlet to any C20-inlet device, serving as a controlled extension between rack power and high-current downstream equipment. One end carries a C14 male plug (MSL-106), the other a C19 female receptacle (MSL-119), connected by 14 AWG SJT three-conductor cable at 9.3 mm OD. Rated 15 amps at 250 volts at the system level; cable rated 300 V / 105°C.

The IEC C14 male plug follows the IEC 60320 standard and is the matching connector for any C13 outlet on a rack-mount PDU, UPS bypass receptacle, or in-rack power strip. Inserting the plug establishes the source-side connection, with molded PVC overmold preventing strain on the conductor terminations. The plug carries the standard "15A 250V" face marking, confirming the electrical rating at the interface and capping the assembly inside the C14 specification ceiling.

The IEC C19 female receptacle accepts any device with a C20 inlet — the high-current cousin of the more common C14. C20 inlets appear on enterprise rack servers, blade chassis, core and aggregation network switches, KVM-over-IP appliances, and UPS bypass cables. The C19 receptacle is rated 16 amps in the IEC spec, but the system stays constrained to 15 amps by the C14 source plug — the most common misconception, addressed in the FAQ below.

UL Listed under file E210037 for both molded connectors and E204978 for the SJT cable, with cUL, CSA, and RoHS compliance. The 14 AWG SJT jacket is rated VW-1 (UL) / FT2 (CSA) self-extinguishing at 105°C and 300 volts, exceeding C14-C19 interface demands by a wide margin. The jacket is permanently marked with UL file number, AWG, voltage, and flame rating, so engineers and procurement auditors can verify against site code at a glance.

Typical deployments cluster around four scenarios: rack-mount server installations bridging a 0U/1U PDU C13 outlet to a C20-inlet server or blade chassis (most common); UPS installations between a bypass C13 outlet and a downstream high-current server; edge compute and network closet feeds to core and aggregation network switches with C20 inlets; and laboratory or industrial workshop benches powering 250-volt instruments from a standard PDU outlet.

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

Compatible with 0U/1U basic, metered, and switched rack PDUs carrying IEC C13 outlets, rack enclosure power strips, and UPS bypass receptacles, plus any equipment fitted with an IEC C20 inlet. The PW128-12XX family is available in multiple standard rack-jumper lengths; this 3ft variant suits mid-cabinet runs and adjacent-rack connections. Black is the standard jacket color; custom colors can be quoted for installations using color-coded UPS-vs-grid feed identification.

Power Cord Comparison: C14 to C19 vs Closest Alternatives

Four IEC and NEMA power cord configurations are commonly cross-shopped against a C14 to C19 power cord. The differences are not just connector shapes — they change the source you can plug into, the load you can power, and the amperage ceiling of the whole assembly. The table below compares all four side by side so the right configuration is clear before purchase.

Choose a C14 to C19 power cord when the rack PDU or UPS has C13 outlets and the downstream equipment has a C20 inlet — the most common configuration in standard server cabinets, accepting that the assembly is capped at 15 A by the C14 source.
Choose a C14 to C13 power cord when the load is a standard 1U server, desktop, monitor, or smaller network switch with a C14 inlet rather than a C20 inlet.
Choose a C19 to C20 power cord when the PDU has dedicated high-current C19 outlets and the load requires the full 16 A IEC ceiling that a C14 source cannot deliver.
Choose a NEMA 5-15P to C19 power cord when no rack PDU is available and the C20-inlet equipment must be powered directly from a 120 V North American wall outlet at the cost of dropping to 125 V / 15 A.

FAQ

What is the difference between a C14 to C19 power cord and a C19 to C20 power cord?

A C14 to C19 power cord plugs into a PDU C13 outlet and feeds a C20-inlet device, constrained to 15 amps by the C14 source plug. A C19 to C20 power cord plugs into a higher-current PDU C19 outlet and feeds the same C20-inlet device, supporting the full 16-amp C19/C20 specification. Choose based on whether the upstream PDU outlet is a C13 (lower-current, more common) or C19 (high-current, less common).

Will an IEC C14 to C19 power cord work with my server's C20 inlet?

Yes — the C19 receptacle on this cord is the matched mating connector for any IEC 60320 C20 inlet found on enterprise servers, blade chassis, network switches, and KVM-over-IP appliances. Compatible C20-inlet devices include 1U and 2U enterprise rack servers, blade chassis, core and aggregation network switches, and similar high-current rack equipment. The C19 receptacle locks against accidental disengagement during routine cable management.

Can a 14 AWG C14 to C19 cord carry 16 amps because the C19 receptacle is rated for it?

No — the system is constrained to 15 amps by the C14 plug on the source side, even though the C19 receptacle is independently specified for 16 amps in the IEC standard. The C14 plug carries a maximum 15A UL rating at 250 volts, and the 14 AWG copper cable is sized to that ceiling. If a load requires the full 16-amp C20 inlet rating, use a C20-source cord (C19-to-C20 or NEMA L6-20P-to-C19) instead.

How do I connect a C14 to C19 power cord between a rack PDU and a server?

Plug the C14 male end into any IEC C13 outlet on the rack PDU or UPS bypass receptacle, then plug the C19 female end onto the C20 inlet on the server, blade chassis, or network equipment. Both interfaces are friction-fit (non-locking) IEC connectors; ensure the cord is routed without tension at either end and secured to the rack cable manager to prevent accidental disengagement during routine PDU work.

Which C14 to C19 power cord length is best for rack-mount equipment?

For most 1U or 2U rack servers with a top-mounted 0U PDU, a 3ft cord routes cleanly with adequate slack for cable management; 1 ft to 3 ft cords suit dense in-cabinet jumper runs where the PDU is adjacent to the server; 10 ft to 15 ft cords cover adjacent-rack feeds or installations where the C20-inlet equipment sits in a different cabinet from the C13-outlet PDU. Match the length to the actual cable run plus 10–15% slack for service loops.
