IEC 60309 plug

Power supply cables play a crucial role in ensuring reliable power delivery for the many components that make up a data center. One type of cable that has gained significant popularity in recent years is the international electrotechnical commission (IEC) cable, with numerous types that have various benefits. Read on as we explore the different types of IEC cables and their applications to improve your data center with the right power cords.

Standard IEC C13 and C14

The most popular type of IEC cable is the C13/C14. The female connector, labeled C13, is a plug connector that accepts three pins arranged in a line. The male connector, labeled as C14, has three pins in a triangular formation. The C13/C14 cable connects a computer or server power supply to a power distribution unit (PDU) or an uninterruptible power supply (UPS).

IEC C19 and C20

Data centers that use high-powered servers and network equipment use C19/C20 IEC cables. The C19 connector handles a higher current rating than the C13 connector, making it ideal for power-hungry devices. The C19 cable fits into the C20 connector, which has a wider spacing between pins to handle the larger cable.

IEC C15 and C16

Another type of IEC cable similar to the C13/C14 is the C15/C16. Both connectors look identical to the C13/C14 connectors, but the C15/C16 handles higher temperatures. The C15 connector has a notch on one of the pins to prevent it from being connected to a C14 socket rated for a lower temperature. These cables are best for applications that require exposure to higher temperatures, such as data centers that use hot aisle/cold aisle cooling methodologies.

IEC Locking C13/C14 and C19/C20

For applications that require a more secure connection between the power supply and the device, use IEC locking C13/C14 and C19/C20 cables. These cables have an additional locking mechanism that prevents accidental disconnection, ensuring secure power delivery.

IEC C7 and C8

The IEC C7/C8 cable, also known as a “figure 8” cable, functions in applications where a small connector profile is necessary. Compared to different types of IEC cables, this cable has a unique design; the C7 connector has two pins arranged in a figure-eight formation, while the C8 connector has two tabs that lock into the C7 connector. Game consoles, small appliances, and audio equipment often utilize the C7/C8 cable.

Data center managers and electrical contractors must understand the various types of IEC cables. Choosing the right cable for the right application ensures that devices remain powered and data flow is uninterrupted.
