They draw power from the main panel and adjust the distribution around an area or property. These are connected to the main panel through a circuit. Subpanels are easy to install, safe, and efficient for residential homes. Subpanels are suitable when multiple circuits are required within the same area. This will then serve as the main breaker and discontinue the power supply even before it enters the property/building. The separate disconnection in the meter can be used during a fire or emergency. Line wires are connected to these lugs, and the main lug panel can be used as a sub-panel when connected to a breaker from the main panel. They are generally used as a distribution box during a main upstream breaker. The most commonly used type is the main breaker panel and is important to have in any property as it:ġ) Protects the circuits and controls the amperage capacity.Ģ) Protects the circuits from getting overheated.ģ) Protects a power supply by shutting down (including the circuit breaker) in case of a short circuit. Type of Distribution Boxes Main Breaker Pane: – Distribute power to different areas from the main power source.ĭifferent types of distribution boards available serve specific distribution requirements, and some are also customizable. – Ensure that everyone and everything is safe against short circuits. – Break up the power supply into sub-circuits depending on the purpose for it. – Best quality wiring should be used to ensure safety. – There should be enough space for other wires, fixtures, and cables. – The fuse should block overcurrent through the circuitry. Working with the wires and cables in an electrical system must be safe, and the distribution boards must ensure the following: – Earth resistance between the electrode and the point of zero potential. – Control and distribution board (consumer unit) – The incoming supply circuit breaker or main switch At a broad level these components will aid in:
A typical electrical distribution box will include a bus bar, fuse links, switches, bypass equipment, and residual current detector (RSD.). The basic structure and technical aspects of electrical distribution boards vary according to places and requirements. The cable is connected to the distribution board and the power is distributed through the breakers in the secondary circuits (lights and plugs) Components of a Distribution Box: The electrical power supply comes from the network to the building through the main feeding cable. As a component of an electrical system: it divides electrical power into subsidiary circuits and provides a protective fuse or circuit breaker for each circuit.Ī distribution box houses all the contact breakers, earth leakage units, doorbells, and timers. It is the central electrical supply system of any building or property. The distribution box serves as the load centre and distributor of electrical power.Ī distribution box ensures that electrical supply is distributed in the building, also known as a distribution board, panel board, breaker panel, or electric panel.
