Distribution Board in Eectrical wiring:

This diagram shows how to connect the distribution board to electrical wiring. In this circuit diagram, we want to describe how a single-phase SDB ( Sub Distribution Board ) wiring can be completed. In this circuit, we use a single-phase energy meter, a DP MCB ( Double Pole Miniature Circuit Breaker), and some SP MCB ( Singe Pole Miniature Circuit Breaker ). If you want more clear details about this diagram please check our youtube video.

Components used to make the Distribution Board in Eectrical wiring:

01. Single Phase Energy Meter

Single Phase Energy Meter
Fig 2: Single Phase Energy Meter
The measuring device with the help of which the electric power or energy of a circuit is measured is called Energy Meter (Energy Meter). Also called a watt-hour or kilowatt-hour meter. For home appliances, we used a single-phase energy meter. The single-phase energy meter is directly connected between the line and the load. Both coils produce their magnetic fields, when the meter is connected to the supply line, and the load. Energy meters are used in homes and in industrial applications where we want to found that how much energy is being consumed by home appliances and electrical equipment.

02. DP MCB

Fig 3: DP MCB
Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

03. SP MCB

Fig 4: SP MCB
MCB SP means single pole it protects only one phase switching. MCB (Miniature Circuit Breaker) Curswitch is the most basic general-purpose switch that you use to control a light or another device from one location. These Switches Have Two Brass-Colored Screw Terminals Connected to the hot Power Source Wires. (MCB) For any Distribution Board, the Protection System Must be Used in The Incomer. Phase and Neutral Single Phase Supply to break. 120-volt circuits, 15-20 amp single pole breaker is typically used.

04. Busbar

Fig 5: Busbar
Busbar is a type of power transmission sheet. It is made of copper or brass or aluminum. Busbar is mostly used in factories. We supply the power from the transformer to the busbar. Busbars have electricity. We take the electricity from this busbar to the circuit breaker. The busbar is drilled with a drill machine and the cable is connected with a nut bolt. The advantage of using a busbar is that through it we can provide multiple power connections in multiple places very easily.

Frequently Asked Questions

How a distribution board is wired?

The main supply cable comes into the board or is then distributed to the breakers and from there to all the circuits lights fan plugs etc. This video shows a Single Phase Distribution Board of the Wiring Diagram. distribution board DB is where the electrical supply is distributed from within the building at home.

What is the importance of a distribution board in domestic wiring?

An electrical distribution board, also known as a panel board and a breaker panel, is a crucial component in the electrical system of a building. It's responsible for distributing electrical power supply from the main power supply to the various circuit diagrams and appliances throughout the building.

What are the main distribution boards?

The main distribution board is a low-voltage switchgear that is installed in a building and its detached part. The MDB is used to distribute electrical energy between the distribution and final circuits diagram connected to it in the entire electrical installation of a building and in some parts of it.

What is 3 phase distribution board?

A 3-phase board, also known as a Three Phase Distribution Board or TPN is an essential part of a 3-phase electrical installation. It acts as a central hub that receives power supply from the electricity grid or a generator and then distributes it to various circuit diagrams within a building or facility.

What is the structure of the distribution board?

A typical electrical distribution board includes the following components – bus bar, fuse links, switches, bypass equipment, and residual current flow detector (RSD). In today's world, safety is of the utmost importance when it comes to working with wires or cables at home.
