Specifies dimensional, electrical and mechanical requirements for bolted flameproof cable coupling devices for coupling two or more feeder cables or for coupling a cable to equipment.

This Standard specifies the dimensional and test requirements for bolted flameproof cable coupling devices and adaptors of the multiple pin and contact-socket type with separate pins, referred to in this Standard as 'cable coupling devices', for use with restricted earth-fault systems in coal mines. The devices are designed to enable feeder cables to be coupled together, or to enable a cable to be coupled to equipment.Cable coupling devices and adaptors to this Standard are not intended to be coupled or uncoupled while the circuit is energized.The Standard prescribes the dimensions necessary to provide for the interconnection of cable coupling devices of different makes; it also deals with some electrical and mechanical requirements including the provision of earthed phase barriers for protection against interphase faults. It does not, however, purport to otherwise specify a fully detailed design.
