This part of IEC 61439 defines the specific requirements for public electricity networkdistribution assemblies (PENDAs).PENDAs have the following criteria:– used for the distribution of electrical energy in three phase systems for which the ratedvoltage does not exceed 1 000 V a.c. (see Figure 101 for a typical distribution network);– stationary;– open ASSEMBLIES are not covered by this standard;– 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 ordinarypersons;– for indoor or outdoor use.The object of this standard is to state the definitions and to specify the service conditions, construction requirements, technical characteristics and tests for PENDAs. Network parameters may require tests at higher performance levels.PENDAs may also include control and or signalling devices associated with the distribution of electrical energy.This standard applies to all PENDAs whether they are designed, manufactured on a one-offbasis or fully standardised and manufactured in quantity.The manufacture and/or assembly may be carried out other than by the original manufacturer(see 3.10.1 of IEC 61439-1:2011).
