GB 16895.7-2000 Electrical installations of buildings. Part 7: Requirements for special installations or locations. Section 704 -- Construction and demolition site installations (English Version)
The specific requirements of this section apply to temporary electrical installations in: construction of new buildings; repair, alteration, extension or demolition of existing buildings; works of public works; earthworks; other similar works. This standard does not apply to electrical installations covered by IEC Publication 60621 or to other electrical installations of a similar nature to equipment used in surface mining. Partial renovations of buildings, such as extensions, overhauls or demolition, are similar to construction sites during their construction, so such works are subject to the provisions of temporary electrical installations. For the administrative facilities of the construction site (offices, cloakrooms, conference rooms, canteens, restaurants, dormitories, toilets, etc.), the general provisions in IEC publication 60364 Parts 1 to 6 are applicable. Note: For special locations, more stringent requirements should apply, for example, in narrow conductive places, the provisions of Section 706 should be complied with. On construction sites, permanently installed electrical installations are limited to complete sets consisting of main control equipment and basic protective appliances (see 704.537). Electrical installations on the load side are considered mobile installations, except for those designed according to Chapter 52 (Wiring systems).
