Specifies 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 and which are for use in public three-phase systems. This Standard is identical with and has been reproduced from IEC 60439-5:1996 and incorporates Amendment 1:1998.

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—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—Where local regulations and practices permit, a CDC according to this standard may be used in other than public networks.
