Tube Light Circuit Diagram With Starter. A wire already connects port 2 and pin 1 of the terminal 2. Different electrical symbols are used to make the wiring diagram below.
The fluorescent tube has two filaments with four terminals the starter is connected between two filaments the ballast is connected between main ac supply. You can see how this system works in the diagram below. I explain how starter of tube light works use of glow starter with connection circuit diagram voltage and current waveforms in this video.
Tube light wiring diagram.
From the junction box the neutral wire is not taken out to the switch board rather it is taken out from the junction box and carried out to the port 2 of the tube light as per figure above. When we connect the ac supply voltage to the circuit then the starter act like short circuited and current flow through those filament located at the first and second end of the tube light and the filament generate heat and it ionized the gas mercury vapor in the fluorescent tube lamp. A wire already connects port 2 and pin 1 of the terminal 2. Tube light wiring diagram.
