AS/NZS IEC 61439.5:2016
Low-voltage switchgear and controlgear assemblies - Part 5: Assemblies for power distribution in public networks
Defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria: used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V a.c.; suitable for installation in places where only skilled persons have access for their use, however, outdoor types may be installed in situations that are accessible to ordinary persons; for indoor or outdoor use. Open assemblies are not covered by this standard. It is to be read in conjunction with AS/NZS 61439.1:2016. Identical to and reproduced from IEC 61439-5:2014, including COR1:2015.
