prefabricated buildings
caravans and caravan sites and similar sites
construction sites, exhibitions, fairs and other temporary installations (future)
docks and marinas (future)
These Rules apply to the following:
circuits supplied at nominal voltages up to and including 1000V a.c. or 1500 V d.c.
circuits, other than the internal wiring of apparatus, operating at voltages exceeding 1000 V and derived from an installation having a voltage not exceeding 100 V a.c., e.g., discharge lighting, electrostatic precipitators
any wiring for telecommunication, signalling, control and the like (excluding internal wiring of apparatus)
These rules do not apply to:
electrical traction equipment
electrical equipment of automobiles
electrical equipment on board ships
electrical equipment in aircraft
