The rules and regulations that are specified in the document are relevant when designing electric lighting, power supply and electrical equipment that is being built, overhauled or is being reconstructed. These devices can be located both in public buildings and in residential buildings or dormitories, urban, rural and suburban type.

As for the power distribution boards and points, the current version indicates that they must be located on the same floor as the electrical receivers that are connected to them. The grouping takes place in accordance with the accounting of the technological purpose of each electrical consumer.
- in public catering networks, you can connect up to 4 devices with a capacity of up to 3 kW and 2 - up to 5 kW;
- in training workshops, up to 5 power devices are connected according to the trunk circuit.
In Appendix 2 and 3 at the end of the document there are diagrams for connecting electrical receivers of refrigeration and technological equipment.
The document describes in detail how to protect internal power grids up to 1 kV. Recommended Appendix 4 contains formulas according to which the rated currents of fuse-links in fuses are selected.
