An electrical distribution board, also known as an electrical distribution box, is an essential component of any electrical system. It is responsible for distributing electrical power to various circuits and devices throughout a building, ensuring that power is delivered safely and efficiently.
Let’s explore the features of electrical distribution boards and the importance of using an electric changeover system.
Electrical Distribution Boards
It is a metal electrical distribution box that contains multiple electrical switches and circuit breakers. It is typically mounted on a wall or installed in a dedicated electrical room connected to the main power supply for the building.
- The distribution board is the central hub for all electrical circuits and devices within the building and evenly distributes the electrical load.
- The central function of an electrical distribution board is to protect the electrical system from overloading, short circuits, and other potential hazards.
- The board trips the circuit breaker or switch when it detects an abnormal current flow, which can prevent severe electrical accidents and damage to equipment.
Types of electrical distribution boards are available, each designed for specific applications. For example, a distribution board distributes power to all circuits within a building, while a sub-distribution board distributes power to a particular area or room.
Distribution Board Components
A typical electrical distribution board consists of several components, including:
- Circuit Breakers – Circuit breakers automatically shut off the power supply when a fault is detected, such as an overload or short circuit. They are essential for protecting the electrical system and preventing damage to equipment.
- Switches – Switches control the flow of electrical power to various circuits and devices. They are available in several types, including single-pole, double-pole, and triple-pole switches.
- Busbars – Busbars are metal bars that attach the circuit breakers and switches to the main power supply. They ensure that power is distributed evenly across each circuit and device.
- Earth Leakage Protection – Earth leakage protection is a safety feature that detects current flow to the earth and shuts off the power supply if it exceeds a safe level. It protects against electrical shock and other hazards.
- Meters -Meters measure the electrical power consumption of the building. They do billing and monitoring functions.
Electric Changeover System
An electric changeover system is an essential component of an electrical distribution board. It switches between two power sources, such as the main power supply and a backup generator, in case of a power outage or other emergency.
The electric changeover system typically consists of a transfer switch that connects to the distribution board and a backup generator or other power source. When the main power supply is lost, the transfer switch automatically switches to the backup power source, restoring power quickly and safely.
Electrical distribution boards are essential components of any electrical system, responsible for distributing power safely and efficiently to various circuits and devices throughout a building.
In addition to the distribution board, an electric changeover system is essential for ensuring an uninterrupted power supply in critical applications. Visit IndoAsian to know more!
