[pdf] Check wires/DIN terminal clasps to be sure that they are installed properly. Single Phase Distribution Box generally consists of Double Pole MCBs, Single Pole MCBs, and RCCBs. Distribution Board or DB is an electricity supply system or a common enclosure that distributes the electrical power feed into subcircuits. It includes isolator, RCCB (Residual current circuit breaker) or RCD (Residual-current device) devices, protective fuses or MCB's (Miniature Circuit Breaker). Use a volt meter to measure voltage at the power supply and at the power distribution box. Long cable runs can result in a voltage drop, which can be solved by using a heavy gauge wire. Connection method: Each switch takes a wire from the incoming point and connects it to the incoming end of the switch, or uses parallel connection to reduce the difficulty.
