PDU Input Connectors

Common PDU input connectors, or power plugs, include IEC C14 and C20 classifications. The International Electrotechnical Commission (IEC) has established standards for electrical connections. IEC C13 and C14 input connectors are frequently used to link electronic devices to AC power. The odd numbers represent female connectors or sockets, and even numbers are the corresponding male connector or plug. The numbered connectors have specific conductor counts, current capacities, and maximum temperature ratings. A C14 connector on a PDU will have three conductors and a 10-ampere current rating. A C20 type connector has three conductors and a rated current of 16 amperes. PDU devices often have multiple C14 input connectors for C13 sockets. Units inside data centres frequently feature C20 input plugs for PDUs with higher current flow demands. The C20 is visually differentiated by its square conductor holes.

Buying a PDU with a UK Plug

A power supply system can include a PDU with a UK plug. A UK input connector often follows the British Standard of BS 1363. This standard specifies the single-phase, electrical power plugs and sockets found in the UK. The standard PDU UK-plug is rated for a max current of 13 amps. It will fit into a BS 1363 type of socket. View our top 10 best PDUs.

Using 16 or 32 Amp Commando Connections

Power distribution units in demanding environments often use 16 or 32 amp commando connections. These input connectors are based on the British standard and originated with the MK Commando brand. A variety of PDU models are available which have compatibility with these commando plug types. A commando rated for 32 amps can be used with a PDU that distributes power in professional IT environments. The 16 amp commando connector also meets many industrial demands.
