Choose IEC Power Cords Built for Data Centers and Technical Equipment
IEC 60320 is the international standard set by the International Electrotechnical Commission (IEC) that is used by most countries. The standards set the specifications for power cords up to 250 volts. IEC 60320 power cords use even numbers for plugs and odd numbers for receptacles.
SIGNAL+POWER stocks IEC/data center power cords by connector type, electrical and temperature ratings, color, length, and use case.
Use this collection to source:
C14 to C13 power cords: for common server, monitor, PDU and IT equipment connections.
C14 to C15 power cords: for higher-temperature equipment and heat-sensitive applications.
C14 to C19 power cords: for equipment that needs a larger IEC C19 connector.
C20 to C19 power cords: for higher-amperage data center and rack-mounted hardware.
C20 to C13 power cords: for connecting C13 equipment to C20 power sources.
IEC splitter cords: where compatible equipment can share a suitable power source.
Global IEC cords: for equipment used across multiple regions.
TwyLock® dual-locking IEC cords: where accidental disconnection would create avoidable downtime.
Match the Right IEC Cord to the Right Connector
IEC cords are commonly chosen by connector pairing.
The cord’s equipment-end connector may be C13, C15, C19, or C21, mating with a compatible C14, C16, C20, or C22 equipment inlet, respectively. On equipment-to-PDU jumper cords, the source end may use a C14 or C20 plug that connects to a compatible C13 or C19 PDU outlet. Always confirm both mating connections and the electrical rating of the complete cord assembly.
For many data center and IT setups, C14 to C13 is a common configuration. It is widely used for servers, monitors, switches, and other equipment with C14 inlets.
For equipment that produces more heat, C14 to C15 may be the better choice. C15 connectors are designed for higher-temperature applications, making them useful around heated equipment or compact technical spaces.
For higher-amperage hardware, C20 to C19 is often the more appropriate route. These cords are commonly used with rack-mounted hardware, larger servers, power distribution equipment and equipment that needs a heavier-duty IEC connection.
Keep Racks Organized and Easier to Maintain
IEC cords are especially useful in environments where power needs to be tidy, repeatable and easy to trace.
A short cord can reduce slack in a rack. A longer cord can help reach awkward power paths without forcing a poor layout. A colored cord can help teams separate A/B feeds, identify equipment groups or assist with identification and troubleshooting. A compatible locking cord can reduce the risk of accidental disconnection.
This is why IEC cords are common in:
- Data centers
- Server rooms
- Network closets
- IT departments
- OEM equipment builds
- Test labs
- Industrial control environments
- Audio/visual installations
- Commercial electronics
Source IEC Power Cords From People Who Understand the Details
IEC connector choice can become confusing quickly.
C13 and C15 look similar, but they are not the same. C14 and C20 are not interchangeable. C13 and C19 connectors have different physical configurations and electrical ratings and mate with C14 and C20 inlets, respectively. North American and IEC or other regional ratings can also differ, even when the connector shape looks familiar.
SIGNAL+POWER organizes IEC/data center cords by connector type, country or region, plug standard and receptacle standard so buyers can narrow the options quickly. For standard purchases, use the filters and product categories. For larger orders, global applications, locking requirements or OEM supply, speak to the team before you buy.
Frequently Asked Question
An IEC power cord is a cord set that uses IEC 60320 connector standards to connect equipment to a power source or another piece of equipment. IEC cords are commonly used with servers, computers, monitors, PDUs, networking hardware, appliances and other electronic devices.
IEC data center power cords are used to connect servers, PDUs, switches, monitors, rack-mounted equipment and other technical hardware. They are popular in data centers because they are available in many connector pairings, ratings, colors and lengths.
C13 is a cord connector that mates with a C14 equipment inlet. On a common C14 to C13 cord, the C14 plug connects to a compatible C13 outlet on a PDU, and the C13 connector connects to the equipment's C14 inlet.
C13 and C15 connectors are similar, but the C15 is keyed for hot-condition applications and mates with a compatible C16 inlet. Choose between them based on the equipment inlet and the required electrical and temperature ratings.
Use a C20 to C19 power cord when the source outlet, equipment inlet, and equipment specifications require that configuration. THese cords are commonly used for servers, PDUs, and rack-mounted equipment, but the permitted current depends on the complete cord sontruction, souce connection, approvals, and country of use.
No. IEC power cords differ by connector type, rating, length, wire gauge, jacket, color, locking function and country approval. Always match the cord to the equipment requirement, not just the connector shape.
Ratings can differ because products are evaluated under different regional standards and certifications. The complete cord rating also depends on the plug, connector, wire gauge, jacket, temperature rating, and applicable approvals. For instance a C20 inlet or plug is rated for 20 amps at 250 volts in North America under UL/CSA standards, but it is rated for only 16 amps at 250 volts across the rest of the world under international IEC guidelines.
A locking IEC power cord is useful when accidental disconnection could cause downtime, data loss, interrupted operations or maintenance issues. Locking cords are often chosen for data centers, server racks, network equipment and other mission-critical setups.
IEC cords come in different colors to help teams organize and identify power paths. In data centers and server rooms, colored cords can help separate A/B feeds, equipment groups, racks, phases or priority systems.
Yes. IEC power cords are commonly used by OEMs, wholesalers, IT buyers and facilities teams that need repeatable supply, consistent specifications and larger quantities.
Before ordering, confirm the source outlet, source-end plug, equipment inlet, equipment-end connector, voltage, current, temperature rating, wire gauge, jacket, cord length, locking compatability, and required regional approvals.
