IEC 61439-5:2023 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…
Graphical symbols — Registered public information symbols
This document specifies graphical symbols for the purposes of public information.
This document is generally applicable to public information symbols in all locations and all sectors where the public has access. However, it is not applicable to safety signs or those sectors subject to specific regulations (e.g. traffic signs on public roads).
This document specifies the original symbols that can…
