Distribution Board Wiring:

This diagram shows how to make Distribution Board Wiring. In this circuit, we use some SP MCB ( Single Pole Miniature Circuit Breaker ), a DP MCB ( Double Pole Miniature Circuit Breaker ), a single phase energy meter, and a neutral and earth busbar. First, we need to input power from the electrical pole to the energy meter, then from the energy meter to input power DP MCB, then from DP MCB to connect all SP MCB circuit breakers. Now this circuit is ready for use. This circuit diagram is very easy to make, for clear details please check our youtube animation video in the below post.

Components used to make the Distribution Board Wiring:

01. Single Phase Energy Meter:

A Single-Phase Energy Meter is a sort of Watt-Hour meter. It consists of two Electromagnets. Single-Phase Energy Meter is also Popularly known as a watt-hour meter. 1 Magnet is called the shunt magnet Ml which is Mounted with a Pressure coil. The Pressure coil is a long coil Made of fine Copper wire that is connected across the Supply single-phase line. Single-phase energy meters are suitable for measuring single-phase AC current flow frequencies of 50/60 Hz, which are used for fixed indoor installation systems.

02. DP MCB:

DP MCB In 2 Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls 2 Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control 2 Different Electrical Circuits at the same time, which allows the Appliances to Isolate safely and reliably. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches and Electrical components.

03. SP MCB:

In single-pole MCB, Switching and protection are Affected in only one Phase. Single phase supply to break the phase only. A single Pole breaker is Typically used with 120-volt Circuits, and a 6-20 amps Miniature Circuit Breaker. They are constructed with one Line Wire and one Neutral wire. A Single Pole switch is the most basic General-Purpose switch that you use to Control a light or another device from one location. These Switches have 2 Brass-Colored screw Terminals Connected to the hot Power source wires. Pole refers to the number of Circuits Controlled by the Switch SP Switches Control only one Switch Electrical Circuit.

04. Busbar:

A busbar is a type of Electrical conductor. It is made of copper brass or aluminum. Busbar is most commonly used in factories. We supply the power from the transformer to the busbar. We take the electricity from this busbar to the circuit breaker. The advantage of using a busbar is that through it we can provide multiple power connections in multiple places very easily. How many thick copper bars are aggregates of busbars? A copper bar is rectangular (rectangular) copper type or triangular in shape.

Frequently asked questions

What is distribution board wiring?

An electrical distribution board (or panel board) is a component of an electricity supply system that divides an electrical power supply feed into subsidiary circuit diagrams, while providing a protective fuse or circuit Diagram breaker for each circuit, in a common enclosure.

What is 3 phase distribution board?

A three-phase board, also known as a Three Phase Distribution Board or TPN is an essential part of a three-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 circuits within a building or facility.

What is a 3-phase 4-wire distribution system?

3-phase 4-wire: This system uses star-connected phase windings and the fourth wire or neutral wire is taken from the power supply star point. If the voltage of each winding is V, then the line-to-line voltage (line voltage) is 3V and the power supply line-to-neutral voltage (phase voltage) is V.

What is a Type B distribution board?

Type B distribution boards have a busbar arrangement and are designed to accept multi-pole and/or single-pole OCPDs. They generally have a vertical busbar with the power supply OCPDs connected to the sides.

What is a 4-way distribution board?

Both 4-way & 6-way DBs are three-phase DBs. In a phase DB, each phase has a certain number of outgoing MCBs according to ways. For example – 4 nos of outgoing MCBs per phase make 4 Way TPN DB (where the user will get 12 (4X3) outgoing MCBs in the DB).
