Short rack jumper

Eaton

Eaton Tripp Lite Series PDU Power Cord, C13 to C14

P004-002-AOR

A two-foot C13-to-C14 PDU jumper in 18 AWG, rated 10 A at 250 V, in orange. Short jumpers are the right default inside a cabinet — the cord reaches the outlet above the device and nothing coils behind the rails.

The colour is the point in a dual-fed rack: run one supply in orange and the other in black and the power path is readable at a glance.

Nobody searches for this until a rack build is most of the way finished and a device inlet does not match the outlet in front of it. The vocabulary is the whole problem: IEC 60320 names the connector types with a letter and a number, the even numbers are inlets on equipment and the odd numbers are the connectors on cords, and the two most common — C13 and C14 — are a matched pair that people routinely reverse when ordering. A C13-to-C14 cord runs from a PDU outlet to a server, switch or power supply, and it is the single most-ordered part in any cabinet.

The second decision is where the other end goes. Inside a rack the cord is a jumper: C14 at the PDU, C13 at the device, and the only remaining questions are length and colour. Outside a rack it is a wall cord: a NEMA plug on one end and a C13 on the other, which is what a desktop, a monitor or a standalone appliance actually needs. Buying one when you needed the other is the most common way a rack build stalls, and the two are easy to tell apart on paper — if the far end has pins for a wall socket, it is a wall cord.

After that, three details decide the specific part. Amperage and gauge have to carry the device: a 10 A cord in 18 AWG covers most rack equipment, and heavier draws move to a different connector family entirely. Length should be measured rather than guessed, because a cabinet full of three-foot cords where one-foot cords would do is a cabinet with an airflow problem behind the rails. And colour-coded cords are worth the small premium anywhere a rack is dual-fed, because it is the cheapest way to see at a glance which side of the power path a device is on. Cords are also a natural line on a larger quote — a rack build usually carries the PDUs, the UPS, the mounting hardware and the installation labour alongside them.

Buyer's checklist

How to choose a power cord for a rack or a desk

  • Read the device inlet first, then the PDU outlet. Even IEC numbers are inlets on equipment; odd numbers are the mating connectors on cords, and reversing them is the usual ordering mistake.
  • Decide jumper or wall cord: a C13-to-C14 jumper runs PDU-to-device inside a rack, a NEMA 5-15P-to-C13 cord runs wall-to-device outside one.
  • Check the amperage and gauge against the equipment's draw rather than against the connector — a connector type sets the ceiling, not the requirement.
  • Confirm the wall-plug standard before ordering. This category carries international plug variants alongside the US ones, and they are only distinguishable from the description.
  • Measure the run instead of rounding up. Excess cord length behind the rails is an airflow and cable-management problem that costs more than the cord saved.
  • Colour-code the two feeds in a dual-fed cabinet. It is the cheapest possible way to see which supply a device is on when something trips.
  • Specify hospital-grade where a clinical environment requires it — the green dot is a certification the cord either carries or does not.
  • Order by the box for a build. Cords are consumed in quantities nobody estimates correctly, and a spares tray is cheaper than an expedited order mid-installation.

Reading the connector codes without a chart

IEC 60320 is a family of appliance couplers, and the naming is more consistent than it looks. Types are numbered in pairs: the even number is the inlet built into a piece of equipment or a PDU, and the odd number one higher is the connector on the cord that mates with it. C14 is the inlet you see on the back of a server, a switch or a rack PDU; C13 is the connector on the cord that plugs into it. That is why a rack jumper is described as C13-to-C14 and why the description reads backwards to people who expect the device end to be listed first.

The pair above it works the same way. C20 is the higher-current inlet found on larger power supplies, UPS units and some PDUs, and C19 is its mating connector — a physically different, larger coupler that carries considerably more current than the C13 family. The two families do not adapt to each other in any way you should buy: if a device has a C20 inlet, it needs a C19 cord and a PDU with outlets that accept one. Checking which family a device uses before ordering the PDU is what stops the entire cabinet's cord list from being wrong.

Length, colour and the cabinet nobody can work in

Cord length is a cooling decision disguised as a purchasing one. A cabinet built with generic six-foot cords ends up with several feet of coiled copper behind every device, which sits exactly where the hot exhaust needs to leave. Measuring the actual distance from each outlet to each inlet and ordering the length that fits — often one, two or three feet inside a rack — costs the same money and produces a cabinet that can be worked in and that moves air the way the layout intended.

Colour is the other small decision that pays back later. In a dual-fed cabinet, running the A feed in one colour and the B feed in another means anyone can see which supply a device is on without tracing a cord by hand, which is precisely the thing you want to be obvious during an incident rather than during a discovery exercise. The same logic applies to labelling: a cord with a legible label at both ends is a cord nobody has to unplug to identify.

Buying cords with the build rather than after it

Cords are the last thing quoted and the first thing that stalls an installation. A rack build has a shape — the enclosure, the PDUs, the UPS, the mounting hardware, the patch cabling and the cords that tie the whole thing to power — and putting that shape on one bill of materials means every part is committed against the same date. Ordering the cabinet and the PDUs properly and then buying cords from whatever is nearest is how a build ends up with the wrong connector family on site.

The same document is the right place for the work as well as the parts. Rack installation, cable management and the commissioning of the power path belong with the hardware, and where a project spans several cabinets or several sites the schedule is easier to hold when one quote carries it. Everything on this page is checked against manufacturer documentation and live catalog data; connector families and ratings are stable, but confirm the specific part number's length and rating at each re-order.

FAQ

Common questions

What is the difference between a C13 and a C14 connector?
They are the two halves of one pair. C14 is the inlet — the male appliance connector built into the back of a server, switch, power supply or rack PDU. C13 is the female connector on the end of a cord that plugs into it. A rack jumper therefore has a C14 on the PDU end and a C13 on the device end, which is why it is sold as a C13-to-C14 cord. If you are looking at a piece of equipment and trying to work out what to order, the inlet on the equipment is almost always a C14.
Can I use a C13 cord where the equipment has a C20 inlet?
No. C19 and C20 are a separate, physically larger pair rated for considerably more current than C13 and C14, and they do not mate with the smaller family. A device with a C20 inlet needs a C19 cord and a PDU with C19 outlets. This is worth checking before the PDU is ordered rather than after, because a cabinet whose larger power supplies need C19 and whose PDU only has C13 outlets is a cabinet that needs a different PDU.
Does cord length affect anything other than reach?
Yes, mainly airflow and serviceability. Excess cord length inside a cabinet coils behind the equipment, which is where hot exhaust air needs to leave, and it makes tracing a specific circuit slow. Measuring each run and ordering the length that actually fits — often one to three feet inside a rack — costs no more than buying generic long cords and produces a cabinet that moves air properly and can be worked in without unplugging things to see them.
What does hospital-grade mean on a power cord?
It refers to a cord and plug assembly built and tested to a stricter standard for grounding reliability and mechanical durability, identified by a green dot on the plug. Clinical environments specify it for patient-care areas because a plug that loosens or a ground that degrades has consequences it does not have in an office. It is a certification the specific cord either carries or does not — check the part rather than assuming it from the brand, and specify it where your facility's requirement calls for it.
Can Uniqcli quote power cords in bulk for a rack build?
