MDB is a panel or enclosure that houses the fuses circuit breakers and ground leakage protection units where the electrical energy which is used to distribute electrical power to numerous individual circuits or consumer points is taken in from the transformer or an upstream panel.
what is changeover panel
the changeover panel automatically switches mains electricity from one supply to another, in the event of a fire or mains power failure to ensure continuity of supply to firefighting lifts.
what is 3 phase generator mean
3 phase generators work by producing three separate waves of ac power that operate in a sequence ensuring that there is always a continuous flow of energy and that the power level never dips as it does with single phase generators.
