AI summary The document provides a table specifying the minimum separation from ground for electrical systems in various conditions, including indoors, outdoors, light snow, heavy snow areas, and areas likely to be travelled by vehicles, based on maximum system voltage.
4.03 Clearances to Building Minimum conductor clearances from buildings shall be in accordance with chart V-4M. Where buildings exceed three storeys (or 15 m) in height, a clear space at least 2 m wide shall be left either adjacent to the...
AI summary This section outlines the minimum conductor clearances required from buildings, including specific requirements for taller buildings and the prohibition of wires rubbing against buildings. It emphasizes the need for clear spaces to allow ladder access for firefighting and applies to all parts of a building, including fixtures and communication cables.
