Distribution board wiring:

This Diagram shows how to make Distribution board wiring. Single phase Distribution board. In this circuit, we use a single-phase energy meter, a DP MCB ( Double Pole Minature Circuit Breaker ), an SPD ( Surge Protection Device ), four SP MCBs ( Single Pole Minature Circuit Breaker ), and two busbars. This circuit is very simple and easy to make. If you want to know more about this circuit please stay with our website and check our youtube video below the post.

Components used to make the Single phase distribution:

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. SPD

FIg 5: SPD

A surge protection device (SPD) or more commonly a surge protector is a device used to protect electronic devices from power surges or transient voltages. A surge protective device is a protective device that limits transient voltages or limits surge current. Surge Protective Devices are Used to Protect Sensitive Electronic Equipment Connected to the Installation such as Computers, Televisions, Washing Machines, and Safety Circuits such as fire Detection Systems and Emergency Lighting. Equipment with Sensitive Electronic Circuitry may be Vulnerable to Damage by Transient Overvoltages.

05. Busbar

Fig 6: 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

What is the working principle of the distribution board?

A distribution board or distribution panel (DP) is an important part of an electricity power supply system. Its job is to split an incoming electrical power supply feed into multiple secondary or subsidiary circuit diagrams. Most of the time, each of these secondary circuit diagrams will be protected with a fuse or breaker.

What is the structure of the distribution board?

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

What is a 3-phase board?

3 phase distribution boards are panels that house the circuit Diagram breakers, ground leakage protection units, and fuses that are used to distribute power supply to individual consumer points or circuit diagrams within a building.

What is MCB in the distribution board?

MCB (Miniature Circuit Breaker) is a distribution power supply box that is fixed or provided in every apartment in modern society and Circuit diagrams. Instead of an MCB box, a 32 Ampere DP switch was fixed that had an on-off switch. MCB box concept didn't exist as they were not aware of such a thing as MCB.

What is an AC distribution board?

A distribution board (also known as a panel board or breaker panel) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit diagram breaker for each circuit.
