This British Standard specifies the dimensional and test requirements for 50 A flameproof restrained and bolted plugs and sockets suitable for voltages not exceeding 650 V, primarily intended for use with mining apparatus which is connected to its power supply by means of a flexible cable. These plugs and sockets incorporate three power contacts, one pilot contact for electrical interlocking, and a scraping earthing contact. Provision is also made for cable couplers, to enable lengths of flexible cable to be coupled together.
