Godown wiring is used to operate lamps / loads in a sequential manner, where only one load is operated at a time. As its name implies "Godown wiring", it is commonly used for switching light in godowns, tunnel structures, long passages ... etc, where light is only required for passage or requires only in one position to the time. The advantage of Godown wiring is that the previous load will be turned off when we normally connect the next load.
Godown Wiring Circuit System
The phase has been connected to the common pole of the first switch. The first shot of the switch has been connected to the load. And the second shot is connected to the common pole of the next switch. Initially, the common poles of all switches are placed on the first shot of the SPDT switch. Then, in such an arrangement, change the position of the switch to the previous load of the second OFF shot and the next shot. By this arrangement, an infinite number of charges may be connected in a sequence.
Switch S1 in the circuit is SPST and the remainder are SPDT (Refer to: electrical abbreviations and complete forms), also called as shift switch. In alignment wiring, loads and switches are usually connected with equal spaces. The gauge of the cable or the load capacity of the wiring must be considered depending on the nominal power and the amount of loads. If the nominal power of all loads is the same, the ideal power consumption will be constant. Because even though the circuit has several charges, only one charge will be ON at a time. Then, the number of loads makes a change only in the length of the wiring and the total resistance of the cable. That is the loss of copper or
the loss of heat in the wiring.
