Water-distributing device (WDD) - low-voltage electrical device containing equipment that provides the possibility of input, distribution and metering of electricity, as well as control and protection of outgoing distribution and group electrical circuits in residential and public buildings, which is placed in the form of appropriate functional blocks in one or more interconnected (mechanically and electrically) panels.
IABs are designed for receiving, metering and distribution of electrical energy in electrical installations of residential and public buildings, as well as for protection of distribution and group circuits outgoing from IABs from overcurrents and overloads.
