NEMA 6-15P to C13 Server Power Cord, SJT Heavy Duty, 15A/250V, UL Listed

 

The CableLeader PW153-1203 is a NEMA 6-15P to IEC 60320 C13 heavy duty power cord that connects a 250V, 15A branch circuit to equipment fitted with a C14 inlet. One end carries a NEMA 6-15P grounding plug for a 250V NEMA 6-15R outlet; the other terminates in a C13 connector that seats into the C14 inlet found on servers, network switches, and 250V laboratory instruments. The assembly is built on 14 AWG SJT cable and rated 15A at 250V, a direct power feed for 200-240V data center loads.

 

The NEMA 6-15P is a 2-pole, 3-wire grounding plug rated 15A at 250V. It is the key point of difference from the visually similar NEMA 5-15P, which carries only 120V. The 6-15P has a distinct blade configuration and seats only into a 250V NEMA 6-15R receptacle, so it cannot be plugged into a standard 120V household outlet. This keying protects equipment by matching the cord to the correct voltage requirement and dedicated circuit.

 

The IEC 60320 C13 end is the device-side connector used across IT and laboratory hardware. It mates with the C14 inlet on power supplies that accept up to 10A internationally and 15A in North American service, which is why C14 inlets appear on rack servers, managed switches, and bench instruments. The one-to-one line, neutral, and ground wiring preserves a continuous protective ground from the 6-15P plug through to the connected equipment.

 

Safety and build quality follow the cord's rating. The 14 AWG conductor and SJT thermoplastic jacket support 15A continuous service on a dedicated 250V circuit, and molded strain-relief ends lock the terminal crimps to the jacket so the assembly survives repeated reconfiguration. UL listing applies to both the plug (file E210037) and the cord (file E204978), with cUL and CSA (file 204790) marks and RoHS compliance for installation in regulated facilities.

 

In practice this cord is the link between a facility's 250V outlet and the C14-inlet hardware in the rack or on the bench. Data center technicians use it to power dual-voltage servers from a 208-240V drop; lab managers run it to 250V test instruments and laser printers; integrators keep it on hand for any device that ships with a C14 inlet and must run on a 250V dedicated circuit rather than standard 120V.

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

 

Compatibility & Ordering Information — PW153-1203 mates with any standards-compliant NEMA 6-15R receptacle and any device fitted with an IEC 60320 C14 inlet, including dual-voltage servers, network switches, and lab instruments from major IT and equipment brands. The cord ships in multiple standard lengths to fit in-rack drops, bench runs, and wall-to-equipment feeds; select the length that matches your circuit layout. Custom lengths, bulk packaging, and OEM kitting are available on request.

FAQ

Q1. What is the difference between a NEMA 6-15P to C13 cord and a NEMA 5-15P to C13 cord?

The NEMA 6-15P delivers 250V; the NEMA 5-15P delivers 120V. Although both end in a C13 connector, the 6-15P plug has a different blade configuration and only fits a 250V NEMA 6-15R outlet, while the 5-15P fits a standard 120V household receptacle. The two are not interchangeable — choose the 6-15P version only when your equipment runs on a dedicated 250V circuit.

 

Q2. Is this cord compatible with my server, switch, or lab instrument?

Yes, if the equipment has an IEC 60320 C14 inlet and runs on 250V. The C13 connector on this cord seats into any standards-compliant C14 inlet, which is the standard input on dual-voltage rack servers, managed network switches, and 250V bench instruments. The NEMA 6-15P end must match a 250V NEMA 6-15R outlet, not a 120V receptacle.

 

Q3. What wire gauge and rating do I need for a 250V 15A circuit?

A 14 AWG conductor rated 15A/250V is the correct match for a NEMA 6-15 branch circuit. This cord uses 14 AWG SJT conductors carrying up to 15A at 250V, about 3,750 watts, with lower voltage drop than 16 or 18 AWG over longer runs. For devices drawing more than 15A or using a C19 inlet, step up to a C19 cord on a 20A circuit instead.

 

Q4. What wall outlet does the NEMA 6-15P plug into?

The NEMA 6-15P plugs into a NEMA 6-15R receptacle — a 250V, 15A, 2-pole 3-wire grounding outlet. Insert the blades straight in until seated; unlike a twist-lock plug it does not rotate. This is the same outlet used for 250V dedicated circuits in data centers, server rooms, and labs; it will not fit a standard 120V NEMA 5-15R household outlet.

 

Q5. Which power cord is best for 250V equipment with a C13 inlet?

For a device with a C14 inlet running on 250V, a NEMA 6-15P to C13 cord on a 15A circuit is the correct choice. Match the device inlet and circuit first: use a 6-15P→C13 cord for standard 250V gear up to 15A, a 6-20P→C13 cord when the outlet is a 20A NEMA 6-20R, and a C19 cord for high-current equipment with a C20 inlet. Select a length that reaches the outlet with a small service loop.
