SDB Distribution Board Wiring | Distribution Board Types

SDB Distribution Board Wiring:

This diagram shows how to connect SDB distribution board wiring. In this circuit diagram, we just try to describe simply how to connect an SDB distribution board wiring to house loads like ( light, fan ), etc. This diagram is for SDB distribution board wiring. So you can wire your Industri or office like this diagram very easily. If you want to learn how to connect this circuit clearly you can follow our youtube video link below.

Components used to make the SDB Distribution Board:

01. TP MCB

Fig 2: TP MCB
The full meaning of MCB is Miniature Circuit Breaker. MCB is an electromagnetic switch or device. If for any reason a short circuit occurs in the supply line or load line (line to line or line to neutral) or in case of overload, the MCB automatically trips and disconnects the main line circuit or household power Connection. TP MCB In Three Pole MCB, Switching & Protection is affected in only Three-Phases and the Neutral is not part of the MCB. 3 pole MCB signifies the Connection of Three Wires for a Three-Phase system R-Y-B Phase. Three-Phase Supply Only Without Neutral.


Fig 3: TP MCCB
The MCCB consists of a bimetallic sheet that expands and contracts when the temperature of the MCCB changes. Due to overload, the bimetallic strip will start to bend and eventually, it will trip if more current flows in the circuit than the predetermined current. The trip mechanism opens the breaker. MCCB stands for Molded Case Circuit Breaker. It is another type of electrical protection device that is used when the load current exceeds the limit of a miniature circuit breaker. The MCCB provides Protection against Overload, and Short Circuit Faults and is also used for Switching the Circuits.

03. SP MCB

Fig 4: SP MCB
In single-pole MCB, Switching & Protection is Affected in only one Phase. Single phase supply to break the phase only. A single Pole breaker is Typically used with 120-volt Circuits, 15-20 amps. They are constructed with one Hot Wire and one Neutral wire. An SP switch 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. Pole refers to the number of Circuits Controlled by the Switch SP Switches Control only one Electrical Circuit.

04. Busbar

Fig 5: Busbar
Busbar is a type of electrical conductor. It is made of copper or 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 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) or copper type or triangular in shape.
