10ft NEMA 5-15P to C15 Heavy Duty Power Cord 14AWG SJT 15A/125V, Black

The PW126-12XX is a heavy duty NEMA 5-15P to IEC 60320 C15 power cord built around a 14 AWG SJT cable assembly rated 15A / 125V. The cord pairs a standard 3-prong North American plug with a high-temperature C15 receptacle, allowing IT installers, data center technicians, and printing administrators to power equipment that specifies a C15 inlet directly from a standard 120-volt wall outlet, rack PDU output, or UPS pass-through receptacle.

IEC 60320 C15 is the high-temperature variant of the more common C13 receptacle. A C15 connector has an extra anti-misinsertion notch and is rated to 120°C, while a standard C13 is rated to 70°C. This difference matters whenever the connected equipment runs hot at the inlet — laser printers with fuser units, certain enterprise network switches, kettle-class commercial appliances, and high-density industrial PCs all specify C15 in their product documentation precisely because a C13 cord is not rated for the temperature their chassis reaches in continuous operation.

The 14 AWG SJT cable provides an electrical headroom that 16 AWG and 18 AWG cords cannot match at sustained 15-amp loads. Three stranded 14 AWG conductors give 2.08 mm² of copper cross-section per leg, supporting the cord's full 15A / 125V rating without derating, with measurably lower voltage drop than the 18 AWG cords typically shipped with desktop PCs and consumer monitors.

Equipment that ships with or requires a C15 line cord includes Cisco Catalyst 3850 / 9300 series switches, HP and Aruba PoE+ switches in the 2530 and 5400 series, HP LaserJet Enterprise M806 and M712 printers, Xerox WorkCentre multifunction copiers, and select Juniper EX-series routers. Always verify the OEM specification sheet for the specific model to confirm a C15 line cord is required.

Typical installation scenarios include enterprise wiring closets where Cisco or Juniper switches sit above a rack PDU, central reprographics rooms where high-volume laser printers run continuous duty cycles, and industrial control cabinets housing SCADA terminals or PLCs that specify high-temperature inlets. The 10-foot length suits in-rack and adjacent-rack deployments without leaving excessive slack in cable management trays. The black jacket provides a professional appearance and suits standard data center and enterprise rack deployments.

Product Comparison: NEMA 5-15P to C15 Heavy Duty vs Standard NEMA 5-15P to C13 PC Power Cord

Buyers often compare a NEMA 5-15P to C15 heavy duty power cord against the standard NEMA 5-15P to C13 PC power cord, since both start from the same US wall plug. The two cords look similar but are not interchangeable — the C15 receptacle has an extra notch and a higher temperature rating, and the heavy duty 14 AWG cable carries more current with less voltage drop. The table below summarizes the decision.

Decision rule: Match the receptacle on the cord to the inlet on the equipment. A C15 plug will not fit a C14 inlet because of the anti-misinsertion notch, and a C13 plug — while it physically fits a C16 inlet — is not rated for the temperature an enterprise-grade chassis can reach during continuous operation. When in doubt, check the equipment's specification sheet for the exact line cord type listed.

FAQ

Q1. What is the difference between a C13 and a C15 power cord?
A C15 power cord uses an IEC 60320 C15 receptacle rated for 120°C operating temperature, while a C13 receptacle is rated for 70°C. The C15 housing carries an anti-misinsertion notch that prevents it from plugging into a standard C14 inlet, so the two cords are not interchangeable on equipment that specifies one over the other.

Q2. Will this power cord work with my Cisco switch or HP enterprise printer?
Yes, this cord works with any equipment that has a standard IEC 60320 C16 inlet — which includes most Cisco Catalyst 3850 / 9300 series switches, HP LaserJet Enterprise M806 / M712 printers, several HP and Aruba PoE+ switch chassis, and Xerox WorkCentre multifunction units. Always check the equipment's spec sheet for "C15 line cord" or "IEC 60320 C16 inlet" before purchase.

Q3. Do I need 14 AWG instead of the standard 18 AWG for my server or printer?
14 AWG cable is recommended whenever the connected equipment draws near the 15-amp circuit limit or runs continuous duty cycles, because the heavier conductors reduce voltage drop and dissipate less heat at the cord. Enterprise laser printers, Cisco switches with full PoE+ loads, and server PDU pass-throughs all benefit from the 14 AWG specification over the 18 AWG cords typically bundled with consumer electronics.

Q4. Which end of the cord connects to my equipment, and which connects to the wall outlet?
The IEC 60320 C15 receptacle (the connector with the notched housing) plugs into the C16 inlet on the back of the equipment, and the NEMA 5-15P plug (the standard 3-prong US plug) connects to a 120-volt wall outlet, rack PDU output, or UPS pass-through receptacle. The cord is not reversible — the C15 end is the female side that mates with the equipment's male C16 inlet.

Q5. Should I choose a C15 cord over a C13 cord for my equipment?
Choose a C15 cord only when the equipment's documentation specifically calls for a C15 line cord or shows a notched C16 inlet on its chassis. Equipment that specifies a C13 cord uses an unnotched C14 inlet, and a C15 receptacle physically will not fit. C15 is the correct choice for high-temperature applications like enterprise laser printers, certain Catalyst switches, and industrial PCs — not a universal upgrade over C13.
