This British Standard specifies requirements for 300 A bolted flameproof cable couplers and adaptors of semi-screened three-phase, or unscreened three-phase with centre pilot tube type, with the following voltage ratings: 1.9/3.3 kV; 380/660 V and 640/1100 V. The couplers are designed to enable two cables to be coupled together or to enable a cable to be coupled to apparatus by use of adaptors, in both cases the electrical connections being made by separate connecting pins. Provision is also made for insulated end covers.
The use of other forms of intermediate box, with coupling arrangements as specified in this standard, are not precluded provided that all other relevant requirements of this standard are met. The semi-screened cable couplers are primarily intended for use with three or four-core wire armoured cables where the fourth conductor is earthed. The cable couplers incorporating a centre pilot are primarily intended for use with three-core wire armoured cables having an additional pilot core(s).
Couplers and adaptors conforming to this standard are not intended to be coupled or uncoupled when the circuit is energized. The dimensions necessary to provide for the connection of enclosures of different manufacture and some electrical and mechanical requirements are specified. This standard does not, however, purport to specify a fully detailed design.
NOTE The figures in this standard show only those essential features and dimensions for function and interchangeability. Dimensions are in millimetres.
