What is Switchboard?
A switchboard is an electrical panel that receives power and distributes it to different circuits, equipment, and areas of a building.
Definition
Purpose
A switchboard is made to safely control and distribute electrical power. It helps direct electricity to where it is needed while providing protection against issues such as overloads and short circuits.
They’re commonly installed as part of the main electrical distribution system and may feed smaller panels, equipment, lighting, HVAC systems, and other building loads.
Examples of Use
- A switchboard can be used in commercial buildings to distribute power to lighting, HVAC systems, elevators, outlets, and other building systems.
- In industrial facilities, it can supply electricity to large machinery, production equipment, and other high-demand loads.
- Residential buildings, especially larger projects, may use switchboards to distribute power across different floors, units, or major equipment.
- In data centers, switchboards help distribute and control power for servers, cooling systems, and backup systems.
- They can also be used on construction sites as temporary power distribution points for tools, site lighting, temporary offices, and other equipment.
Notes
- Switchboards are generally part of the main or larger-scale electrical distribution system.
- They can contain multiple circuit breakers, switches, busbars, and protective devices.
- Switchboards are typically designed based on the building's voltage, current, and overall power requirements.
- They should be properly sized, installed, and maintained to support safe and reliable power distribution.
- A switchboard is different from a smaller distribution panel, although both are used to distribute electrical power.
