**Assalamualaikum Everyone.** I am [@imranhassan](https://steemit.com/@imranhassan) From [#Bangladesh](https://steemit.com/trending/bangladesh)

How are you all? Hope you are well. Alhamdulillah I am also well. In today's post, I am going to share with you an electricity distribution system diagram, which shows the distribution of power from the grid pole to a sub-distribution board. I have made this diagram completely by hand so that you can understand it easily. ![SC S25W2 Dibujando animé shonen.

This system shows the components used in a typical electrical supply path, such as the **grid pole, meter box, DP MCB (Double Pole Miniature Circuit Breaker), SPD (Surge Protection Device), Miniature Circuit Breaker (MCB)**, and the connection of the grounding system. Every component of the circuit is connected correctly, which ensures a safe power supply and creates efficient management. Components used and their functions:| |-| **Electric Grid Pole:** ![21.png](https://cdn.steemitimages.com/DQmaifUbPgzzBwYzkAtYzcjPSR38FjLT5pc5JohXeDs21ER/21.png)| |-| Edited with Canva. It is the main source of external power supply, which sends the supply to the meter box. **Electric Meter:** ![22.png](https://cdn.steemitimages.com/DQmWgnHbUae4uU8a8GzN4xhdqtsiJ5biegLdzqPspK58DwD/22.png)| |-| It is used to measure the electricity consumption and is necessary for the billing system. **DP MCB - SP MCB (Double & Single Pole Miniature Circuit Breaker):** ![23.png](https://cdn.steemitimages.com/DQmceHD2BVkYatoyeeP2UrF5BEXoeTJ2tdFvn9HqcqqMLCH/23.png)| |-| It automatically operates in case of any electrical problem or overload in the circuit, ensuring the safety of the system. **SPD (Surge Protection Device):** ![24.png](https://cdn.steemitimages.com/DQmVmzus8iysniqD9ArxiwxFZetbAjdowy4DgKxTHtftFsw/24.png)| |-| It protects the system from severe electrical surges and ensures a safe power supply. **Grounding System (E):** ![25.png](https://cdn.steemitimages.com/DQmRqENkbgXW9JW7fKhXL9CSLgPo4Bt2S5k2iBVXaCfhTMY/25.png)| |-| It provides protection to the system from all unexpected power failures. Step 1: Electric Pole to Meter Connection| |-| ![image.png](https://cdn.steemitimages.com/DQmSz8sBTaeYBmrJPtHxdtoj7N5hgyVXxneeNVyF7F8Lw3A/image.png)| |-| First, I took the power supply from the electric pole and connected it to the electric meter. This is basically the first step of the power system, where the power comes from the grid pole to the meter box. Step 2: Double Pole MCB Connection| |-| ![image.png](https://cdn.steemitimages.com/DQmaxyfrSMUhxrMg2XMCA9nhPwwNmH8r575uvpNrAkvDBEN/image.png)| |-| Then I took the power line from the electric meter and connected it to the DP MCB. This DP MCB automatically works during overload or short circuit in the system and closes the circuit and protects it from damage. Step 3: SPD and Earthing Connection| |-| ![image.png](https://cdn.steemitimages.com/DQmdfPyDYV3Wutm8uhgZD4scT5Quj5vEHYGxxK4pgEL5NFJ/image.png)| |-| Then in this step I connected the SPD (Surge Protection Device), which protects the system from electrical surges. After this, using the green wire for the earthing system, I properly brought the line to the ground through the earthing connection. In this way, the excess electricity goes to the ground through the earthing connection. Step 4: Neutral and Circuit Breaker Connections| |-| ![image.png](https://cdn.steemitimages.com/DQmc2Z8Rof2i5kaMi4tr5wv2tGsdQYMo1Cpzd3StJNn6wnz/image.png)| |-| Then in the very last step, I completed the neutral connection with the black wire at the top. After this, I connected four Single Pole MCB circuit breakers to the phase line, which helps to control each room separately. Apart from this, I provided separate connections for Room-1, Room-2, Room-3, and Room-4. This provides the facility of controlling the power supply to each room. Conclusion:| |-| ![image.png](https://cdn.steemitimages.com/DQmZbG5GhPz39Y9YWJSrA86XagAUME285o1q8jTAvgutWQe/image.png)| |-| This is a basic power distribution system diagram, which ensures proper and safe distribution of power supply. Every component is properly connected so that the power can be distributed without any kind of electrical problem or hazard.
