The godown wiring method is popular for warehouses where there is one entrance and the lighting should be on only in the occupied area.

Although this is a method of switch wiring that works quite well it does have one drawback because the lighting will work for only one occupant in one area.

If an additional person enters the warehouse and turns on the switch near them then it will turn off the light where the first person is located.

The traditional godown wiring method is explained here starting with the layout of a warehouse application. For simplicity, the warehouse has three lights and three switches with equal spacing in between. This design could be adjusted and adapted to any size warehouse and adjustments to the size of the circuit will need to be adjusted for the total load, or watts of the actual lighting that will be used and the size of the wire will need to be adjusted for voltage drop in a large warehouse or building.

It should be noted that this design specifies 230 volt 50hz, however this wiring method could also be used for 120 volt, 60 hz, or any other voltage as long as the wiring, light fixtures and switches are rated for the same voltage and application factors.
