H02B BOARDS, SUBSTATIONS OR SWITCHING ARRANGEMENTS FOR THE SUPPLY OR DISTRIBUTION OF ELECTRIC POWER
Description
H02B covers electrical equipment and installations that organize and manage power distribution from generation sources to end users. This includes control boards, switchboards, substations, switching apparatus, and their associated structural frameworks and components used in power supply networks. The classification encompasses both indoor and outdoor installations, protective devices, and the arrangement of conductors and equipment within these distribution systems. Adjacent classes H02G (wiring, cabling) and H02M (conversion of electric power) handle transmission infrastructure and power conversion separately.
