  • the prior art pre-fabricated wiring harness system of German origin is illustrated in Figs. 1-3.
  • the wiring harness 1 (Fig. 3) is formed from a predetermined length of cable 2 having a male connector 3 and a female connector 4 and is manufactured by the firm WIELAND of Bamberg of Germany.
  • the distribution block 5 illustrated in Fig. 3 enables various lengths of cable 2 to be inter-connected in branching fashion.
  • the housing 7 interconnected by the wiring harness 1 is positioned at each location where power utility devices 8 are required.
  • power utility devices are general purpose outlets 9 and a spare cover plate 10.
  • Located within the housing 7 is a male plug 11 and a female plug 12.
  • the plugs 11 and 12 are directly connected to each other and also are connected to each of the general purpose outlets 9 by means of conventional wires 13.
  • the conventional wires 13 are required since the outlets 9, housing 7 and plugs 11, 12 are invariably produced by different manufacturers.
  • the housing is manufactured by the firm MEYER of Dorentrup-Humfeld of Germany
  • the outlets 9 are manufactured by the firm HPM of Sydney Australia
  • the plugs 11, 12 are manufactured by the abovementioned firm Wieland of Germany.
  • the abovementioned system provides the advantage of relatively quick installation but provides the disadvantage of the need for time consuming and expensive manual interconnection of the wires 13 thereby possibly leading to error, injury, damage and the need for a fault-finding procedure. Also if an additional outlet 9 is required, the cover 10 must be discarded and the housing 7 internally re-wired.
  • Fig. 4 illustrates an arrangement sold in the USA by the organisation STEELCASE which is particularly adapted for use with de-mountable partitions.
  • an extremely elaborate harness 20 is used to provide power between adjacent connector blocks 21 each of which is able to receive a single power outlet 22 (which may itself be a dual or triple power outlet) on either side of the wall or partition.
  • This system suffers from the disadvantage that if it 1s decided at a later date that an additional power outlet 22 is required at the given location, it is sometimes possible for the system to be dis-assembled and further connector blocks 21 and extra lengths of harness 20 to be supplied so that the additional outlet or receptacle 22 can be both mounted and electrically connected. This is only possible if the partitions are able to receive the extra connector block(s) 21.
