An electric switchboard is a mechanical apparatus that transfers current from one source to another point connected to the board. As outlined by the National Electrical Code (NEC), an electrical switchboard is a panel on which are mounted switches and other various electrical safety instrumentation, such as circuit breakers. The source of the electric power can be a generator or another capable machine that feeds the necessary current. Essentially, the switchboard can control the directional flow and voltage of current, making it easier to avoid overloads that could damage the board or any other recipient device.

Switchboards transmit power to transformers, panel boards, control equipment and ultimately to system loads. Electrical switchboard installation is set up as a sequence of interconnected panels. Each electrical panel has its chain of switches that make it possible to control the flow of the electricity. The switches can be used to adjust the voltage transmitted to the adjoining device. This ensures that the voltage of the electricity flowing through the system in overly strong that it will cause harm. This increases safety for utilizing electricity in a variety of applications and industries.

One of the jobs of an electric switchboard is to allocate ‘current’ to every gadget. The measure of current distributed depends on the measure of energy that is essential for operation. Meaning, the switchboard gets a steady stream of current from a source and that current is then diverted in littler additions to each of the connected gadgets, given the present status of each. As more gadgets are initiated, the stream of energy is changed by considering a bigger request. If less present is required for operation, a change will be made as to keep any over-burden to the wiring or hardware. As a result of the way its setup, the amount of energy that is streaming into the switchboard must match the measure of current that in the long run streams into the connected gadgets. As a result, steps must be taken to adapt the flow of power to be equal to the rate of consumption almost instantaneously. This is achieved through the constant transfer of data and measurements between the power source and the switchboard.

Electrical switchboards are mostly used in various types of control systems including power plant facilities, transformers that are part of a power grid, and other types of machinery that are powered by electric currents. Continuous advancements in consumption and distribution technology have allowed for even greater control of electricity and the ability to maximize output more efficiently.
