Electrical distribution board of Home and Industry Installation

In electrical distribution each voltage is step down at substation and finally we receive 230V/415V to our home or to industrial areas. So this voltage is flow through the Distribution Board and we able to control the circuit for our own need.

 We see this this kind of board in our home and some industrial areas as the image shown. We describe each of the equipment in the last blog. So now lets see how to wire industrial and domestic distribution board.

1) Domestic Distribution box (Single Phase)
  
In domestic distribution in our home,the wiring is simple (Piece of Cake). Just you need single phase main switch,RCCB and MCB. Now see how the wiring goes as the image shown.

 
Very simple right.But every house loads like fans,lights,sockets are different. So more MCB are needed to wire those loads. So as the wiring above this is image shown the distribution board after wiring.

2) Industrial Distribution Board (Three Phase)

Industrial distribution board are common used in Industrial.But also used in house like double story,bungalow and so on.This is because when the loads are much heavier so single phase current can't power all the loads. So three phase current are used to provide heavier loads like more air-conditioner, Induction stove and so on. So lets see the wiring of industrial distribution box.

You need three phase main switch,RCCb and MCB. As the picture shown,each phase connected through one MCB. Another image shown after wiring installation.

Now you are able to wire single phase and three phase to your home electrical distribution board.

SO YOU ARE A TECHNICIAN FOR YOUR HOME!!!!!!!!!!!!!!
