How to wire a lighting circuit. Another major defect of series lighting circuit is that as all lamps or bulbs are connected between line l and neutral n accordingly if one of the light bulb gets faulty the rest of the circuit will not work as the circuit will be open as shown in fig below. A lighting circuit can serve up to 12 x 100w bulbs. Pin1 of both the switches are connected with the phase or live wire and pin2 of both the switches are connected with the one end of the lamp. Cable will be used for lighting. The other end of the lamp is connected with neutral line of ac power supply. Battery runs out quicker for dc installation.
