Main Distribution Board is a panel from where electrical energy is taken out to distribute power to various consumer points. It typically has a single or multiple incoming power sources and includes circuit breakers and protection devices. MDB then feeds SMDBs, which is installed generally at the point where a large distribution cable terminates and several smaller sub-circuits start. The SMDB feeds the Final Distribution Board, which then feeds electrical energy to the end user.
