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 Diagram for Single phase Wiring with DP MCB, SP MCB, earth, voltmeter, ammeter for Home wiring
In the above diagram I have 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 for this board in E wiring is that we can control the complete wiring from this place. That’s why we can call him the main circuit breaker box. In the above image, I provide the complete instruction needed however let do study some parts in detail.
So let’s disuse the distribution board wiring diagram step by step. In the diagram, I start from the utility pole to the energy meter. So let’s do it step by step with examples.
Energy meter wiring
In the above diagram, I have taken the electric supply from the utility pole to the single phase energy meter and then I connect the supply to the distribution mainboard. If you did not know about the energy meter wiring then read the below post
Double Pole Circuit Breaker
In the mainboard, I first wired the double pole or DP MCB circuit breaker. MCB means Miniature Circuit breaker. If you want to learn more about DP circuit breaker 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 for high ampere or load which are 20A. If you want to learn about one pole breaker wiring then do click on the below post link.
How to wire one pole breaker?
For different loads, we use different types of electrical cables, and in every electrical project, we use the cable size regarding the load. For example for the 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 have shown the electrical cable with its size in mm in which are 6mm or 8mm, 4mm, 2.5mm, and 1.5mm electrical cables.
The connectors did their duty very well in Electrical wiring, this is the easy and compatible way of getting connections or joints in electrical wiring. My suggestion is that use always the connectors in the main distribution board wiring.
The earth connection is very important in electrical wiring/ electrical technology. In the above diagram is shown earth symbol and I have shown how to do the wiring of the earth or earthing. However soon I will write deeply about earthing.
Ampere Meter and CT Coil
The Ampere meter is very important in the distribution board because this device showed the total current (Ampere) getting the complete circuit or a load of the complete circuit. I have shown in the above diagram, how to wire an ammeter with CT current transformer, however, for better understanding visit the below link.
Volt meter / Voltage Meter
I also have shown the wiring of the voltmeter in the main D board. In the main D circuit breaker board, the voltmeter is a very important connection because this makes us know about the receiving voltage to the circuit. Also, read below.
This indicator makes the mainboard beautiful and easy to know about receiving the electric supply if the mainboard supply starts the indicator shows the supply by a glowing bulb.
I spend a big time making this post and distribution board wiring diagram and it’s just for you guys that you learn something clearly, but if I do hard work then it’s your responsibility to make this site popular all over the world by following, Emile subscriptions, Likes and Shares.
INSHALLAH soon I will make a distribution board wiring diagram for 3 phases and for different loads.
