Low-voltage switchgear and controlgear - Part 1: General rules
Scope and object This standard gives supplementary requirements for cable distribution cabinets (CDCs)@ which are stationary@ type-tested assemblies (TTA) for outdoor installation in places which are exposed to the public@ but where only skilled persons have access for their use. They are for use in public three-phase systems. NOTE 1 ?C If a CDC is equipped with additional equipment (for example meters)@ in such a way that the main function is changed considerably@ then other standards may also apply as agreed between user and manufacturer (see 7.6).NOTE 2 ?C Where local regulations and practices permit@ a CDC according to this standard may be used in other than public networks.
