Nippon Labs 18AWG Power Extension Cable, Red C14 to C13, SJT 10A 250V

A red 18 AWG jumper with an IEC 60320 C14 plug at one end and a C13 connector at the other, rated 10A at 250V. This is the cord that goes between a rack PDU or UPS outlet and a piece of equipment. It is the same shape as the cord your server shipped with, minus the wall plug. The red jacket is there for identification: colour-coding A and B feeds, or one customer's kit, saves real time when you are tracing cords behind a full cabinet.

• Extends the length of an existing power cord for more flexibility.
• Connects computer equipment to a PDU or UPS in a data center.
• Red jacket for easy identification in a high-density data environment.
• Heavy-duty 18 AWG cord, fully molded for durability.
• UL, cUL listed and CSA approved.
• All relevant materials comply with the RoHS and REACH directives.

What it's for

• Connecting servers, switches, KVMs and appliances to a rack PDU or UPS.
• Extending an existing C13 cord that will not quite reach the outlet strip.
• Colour-coding redundant A and B power feeds so a mis-patch is obvious.
• Replacing a cord that is too long, so cable management stays tidy in a shallow cabinet.

Good to know

Which end goes where?
The C14 end is the male plug, so it goes into the PDU, UPS or extension outlet. The C13 end is the female connector and goes onto the equipment inlet. Because it is C14-to-C13, it can also sit in-line between an existing cord and its device.

Is this a "jumper" cord?
Yes. C14-to-C13 cords are usually called jumper or PDU cords, because they jump from a rack outlet to a device rather than reaching a wall socket.

Can I daisy-chain two of them?
Physically yes, and it is common practice to extend a run. Electrically, keep the total length sensible and stay well inside the 10A rating; every extra connector pair is another place for a loose contact.

What does 18 AWG mean here?
AWG is conductor thickness, and the scale runs backwards: a lower number is a thicker wire. At 18 AWG this cord is built to carry its rated 10A at 250V without the conductors heating up. A thinner cord with a higher AWG number carries less current.

What is a SJT jacket?
SJT is a thermoplastic-jacketed, hard-service cord, the heavier, more abrasion-resistant jacket used on equipment and rack cords.

How much load can I actually put on it?
The cord is rated 10A at 250V. The usual engineering practice is to keep a continuous load at or below 80% of a circuit or cord rating and leave headroom for inrush when equipment powers on, so size the cord to the equipment rather than to the outlet.
