    Ring main unit and distribution box

    The ring main unit, also called the distribution board or distribution box, is where the power is distributed from the fuse box to various outlets and appliances in the building. It typically contains a number of switch sockets, light switches, and other electrical connections. It includes in one unit two switches that can connect the load to either or both main conductors, and a. Ring Main Units are compact modules that are gas-insulated and sealed, comprising main switching devices and ancillary components to ensure continuous secondary power distribution. According to IEC 62271-200 standards, RMUs serve as load connection points in ring-type distribution. What is a Ring Main Unit? In an electrical power distribution system, a ring main unit (RMU) is a factory assembled, metal enclosed set of switchgear at the load connection points of a ring-type distribution network.
