Types of Power Cables: The Ultimate Guide

If you just moved to a foreign data center, it will be rather difficult to determine which cord is used where and for what. Therefore, it is important to know the different types of power cables and connector standards that countries use.

Different Types of Connectors and Plugs.

Caption: Different Types of Connectors and Plugs.

International Standards IEC 60320

IEC 60320 is a set of standards that specifies power cord appliances up to 250 V. Although different countries use different power cord standards and types, IEC 60320 is internationally recognized and used worldwide. Different types of connectors are specified for various combinations of temperature, current, and voltage.

The connector types C19, C15, and C13 are mostly used in data centers. The table contains further information.

Connector TypeMax Pin Temp (0C)Max Voltage/CurrentCommon Application
C1970250V/16AUsed in devices that need higher current than what the C15 and C13 connectors can’t. Common applications include PDUs, chassis switches, and enterprise-class servers.
C15120250V/10AUsed in high-temperature settings like computer networking closets, PoE switches with high-wattage power supplies and electric kettles.
C1370250V/10AOften work with inlets on computers and various devices that can connect to a computer. 

North American: NEMA 5 – 15P (Type B)

In most of North America and a few other countries, the NEMA standard is the most commonly used standard. Most sockets use the NEMA 5-15P plug, which has three hot wires (ground, hot, and neutral) and a rating of 250V at 15A.

The NEMA 5-15R to the NEMA 5-515P power cable is the most popular option. The NEMA 5-15R refers to the receptacle, while the NEMA 5-15P refers to the plug. 

Europe: CEE 7/7 (Type E, Type F)

In Europe, the CEE is the go-to cable standard option. However, some countries in Europe don’t use the standard CEE 7/7. These include;

Other Standards: JIS C 8303, AS/NZS 3112, Etc

Other countries outside of North America and Europe adopt different standards. However, you’ll find that most use the IEC 60320 connector standard. Other standards include;
