1 Scope This document 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 AC (see Figure 101 for a typical distribution network) and DC systems not exceeding 1 500 V DC; stationary; open type assemblies are not covered by this document;
suitable for installation in places where only skilled persons have access for their use, however, outdoor types can be installed in situations that are accessible to ordinary persons
intended for use in energy distribution in public power grids; indoor use: assemblies for installation inside of electric power substations; outdoor use: assemblies containing an enclosure suitable for open air installation.
