Abstract :
In recent years, industrialised-building techniques have developed to the extent where the time required to construct the main framework and shell of a building is far exceeded by the time required to install the internal electrical services and fittings. To rectify this undesirable situation, pre-fabricated and pre-packaged complete wiring systems are marketed; they are intended to increase the productivity of the available labour force to enable it to keep pace with the increasing rate of building construction.
