Connector types

Commando socket

Commando socket is a common UK trade name for an IEC 60309 industrial plug and socket. IEC 60309 connectors are rugged, keyed industrial connections available in several voltage, current and phase configurations. They are not inherently three-phase. Single-phase blue IEC 60309 sockets and three-phase red versions are both common. Industrial sockets can supply portable or specialist EV charging equipment where the electrical installation is designed for it, but the socket alone does not provide the control and protection functions of EVSE.
