The working project of lighting for a 2-storey school provides for the connection of power electrical equipment and electrical lighting of the building.
In terms of the degree of reliability of power supply, the building belongs to category II. For the distribution network of working and emergency lighting, distribution cabinets of the ShRE-3 type are provided with an input circuit breaker, as well as with feeder circuit breakers for the electric lighting network and switches with differential protection at Iout = 30mA for the household outlet network. Work and emergency lighting boards should be installed in wall niches in lockable cabinets. Lighting standards for premises are adopted in accordance with SP 52.13330.2016. Lighting calculations were made using the utilization factor method.
The type of luminaires was chosen taking into account the purpose of the premises. The power supply for the working and emergency lighting boards is provided from the input-distribution device of the ASU installed in the switchboard in the basement.
Group distribution networks are designed with a VVG-0.66 cable, laid hidden: along the wall, in the voids of floor slabs, in a corrugated pipe along the wall and under the roof - in the technical underground; in steel pipes - in the attic.
Lighting switches and sockets in rooms for children are installed at a height of 1.8 m from the floor, in other rooms, switches at a height of 1.5 m, and sockets up to 1 m.
