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.
