Distribution Board Wiring For Single Phase Wiring

When we start a project of electrical wiring the first and the main control point of wiring is distribution board. Distribution board wiring is very important for controlling the E wiring. For this post i designed a diagram about distribution wiring, we can called this circuit breaker or controlling fuse box. In the diagram is shown the method of wiring distribution main board form utility pole to Energy meter and then DP circuit breaker and SP MCB breaker.
However we study all step by step distribution board wiring below, as we talking about the distribution main board diagram, first see this.

How to Distribution Board Wiring for Single phase Wiring with Dp MCB, sp mcb, earth, voltmeter, ammeter for Home wiring

In the above diagram i shown the complete method of wiring, i wired an energy meter after that a double pole and then single pole breakers for each room or each point of circuit load. The main reason of this board in E wiring is that we can control the complete wiring form this place. That's why we can called him the main circuit breaker box. In above image i provide the complete instruction which needed however lets do study some parts with details.

So lets disuse the distribution board wiring diagram step by step. In the diagram i start form utility pole to the energy meter. So let's do it step by step with examples.

Energy meter wiring

In the above diagram i taken electric supply form utility pole to single phase energy meter and then i get supply to them distribution main board. If you did not know about the energy meter wiring then read the below post
How to wire single phase energy meter?

Double Pole Circuit Breaker

In the main board i first wired the double pole or DP MCB circuit breaker. MCB means Miniature Circuit breaker. If you want learn more about the DP wiring then Click on the below link.

Single Pole MCB breaker

In the above distribution board wiring diagram i wired 8 single pole breakers in which some are for low ampere (10A) and some are for high ampere or load which are 20A. If you want to learn about one pole breaker wiring then do click on below post link.

Electrical Cables

For different load we use different types of electrical cables, and in every electrical project we use the cables size regarding the load. For example for Air conditioner we use the 4 mm cable which is very good for this, however if we use 2.5 mm then it's will not good for all time.
In the above diagram i sown electrical cable with it's size in mm in which are 6mm or 8mm, 4mm, 2.5mm and 1.5mm electrical cables.

Electrical Connectors

Connector done his duty very well in E wiring, this the easy and compatible way of getting connection or joints in electrical wiring. My suggestion is that use always connector in main distribution board wiring.

Earth Connection

Earth connection is very important in electrical wiring/ electrical technology. In the above diagram is shown earth symbol and i shown that how to do wiring of earth or earthing. However soon i will write deeply about earthing.

Ampere Meter and CT Coil

Ampere meter is very important in distribution board because this device shown the total current (Ampere) getting the complete circuit or the load of complete circuit. I shown in the above diagram that how to wire a ammeter with CT current transformer, however for better understanding visit the below link.

Volt meter / Voltage Meter
I also shown the wiring of volt meter in main D board. In main D circuit breaker board volt meter is very important connection because this make us know about the receiving voltage to circuit. Also read below.

Indicator Bulb
This indicators make the main board beautiful and easy to know about receiving electric supply, if the main board supply start the indicator show the supply by glowing bulb.

Message:

I spend a big time in making this post and distribution board wiring diagram and it's just for you guys that you learn some thing clearly, but if i do hard working then it's your responsibility to make this site popular in all over the world by following, Emile subscriptions, likes and Shares.
INSHALLLAH soon i will make distribution board wiring diagram for 3 phase and for different loads.

  1. very good but can you explain that why we need to put 10amp 20 amp circuit breaker what is reason and if it is possible can you show us may be 1 or 2 rooms connection with the main board will be great full any way your teaching is very good and very clear to understand will be looking forward to see your next post regarding this Many Thanks
    a

  2. sir,
    what is the ct coil details, that is connected to the Amps meter.
    thanks

    1. Dear CT mean current transformer which we use with ampere meter where the high current flow to circuit. In low current flow circuit we use those types of ampere meter which we connect in series but in high current flow circuit we use ct coil for ampere meter. but the current transformer and series connection ampere meter is different. you will learn all about current transform connection diagram by using below link.

  3. Hi, I bought 4p MCB . in your diagram the current flows from top to bottom, but here so many house they have connected bottom to top. Is it possible to flow from bottom to top.
    And what that in MCB 1-2 3-4 5-6

    1. Yes it is possible to flow form bottom to top. MCB breaker is like a one way switch. If you connect your incoming supply to top and get form bottom then it's working and if you connect the your power supply for bottom to top then it's also work same.
