Limit values for humidity and air quality e g. Stand alone packages. This ifs assembly can incorporate normal main switchboard structures along with structures that incorporate multiple panel boards per structure usually two as well as dry type transform ers. Together with the actual equipment sizes this defines the overall minimum dimensional requirements of the room.

An electrical room is a room or space in a building dedicated to electrical equipment. Large buildings may have a main electrical room and subsidiary electrical rooms. In order to design a good ventilation of switchgear and transformer rooms the air in the room must meet various requirements. Article 408 contains the requirements for switchboards panelboards and distribution boards for light and power.
