[Dozer 73]

704 Construction and Demolition Site Installations
704.411.3.1 A TN-C-S system shall not be used for the supply to a construction site, except for the supply to a fixed building of the construction site.
NOTE: The ESQCR prohibit the use of a TN-C-S system for the supply to a caravan or similar construction
