Light Indicator Wiring Diagrams For 3 Phase Voltage Coming Testing

In power wiring or 3 phase 4 wire system, we used the 3 phase power of all electric induction motors, equipments etc, but we did not ignore the neutral wire or ground wire. In many place we required neutral wire to complete circuit. But This is also important to know about our lines or 3 phases that these 3 phase wire properly working or are every phase incoming supply is coming properly and not cut or broken in main power supply wire. So this very important to test or know about our 3 phase supply coming properly, for that we use led indicator and this post is also about indicator wiring diagram.
Yes this connection is very important and we do it any every main 3 phase panel board. In this post i will share with 2 diagrams about led light indicator wiring, '' in which one is image+diagram and second is symbol diagram.

How To Wire Led Light Indicator For 3 Phase 4 Wire System 

So first we discus image diagram which i make for your better understanding. In 220 led indicator required 220V electric supply and i also shown below 220 volts light bulb indicators with 3 phase 4 wire supply.
In AC indicator we have two terminals or links where we connect the electric supply, So as we do this wiring for 3 phase that's why we will wire 3 light indicator. In this connection first we connect neutral / ground wire to all indicators and then we connect one - one phase to indicators as shown in below diagram.

The above image diagram is only for your better understanding, But i know that you can not learn completely from above led indicators diagram, that's why i also designed a indicator symbol wiring diagram which i shown below.
led indicator wiring diagram
In Above symbol diagram i shown a 3 phase power 440 volts source with three 220 volts light indicators, note that between neutral and phase the voltage will be 220V and between two phase voltage will be 440 volts but this only for some places.
Wired indicators for 3 phase as i shown in above diagrams.

I hope after these two indicator wiring diagram, you will completely understood, however now if you have any question regarding this post then you can ask me in below comments section.
