Which device allows the distribution of current supplied into smaller currents?

The device that allows the distribution of current supplied into smaller currents is the switchboard. A switchboard serves as a centralized location where electrical power is distributed to various outgoing circuits. It is designed to manage large amounts of electrical energy and distribute it safely and effectively.

Switchboards typically contain circuit breakers, fuses, and other protective devices that allow the electrical flow to be divided into smaller, manageable currents for different areas or devices within a facility. This feature is crucial for ensuring that the electrical supply is used efficiently and safely by preventing overloads and enabling proper maintenance.

While the other options may have roles in electrical distribution, they do not function primarily to break down larger currents into smaller ones in the same way that a switchboard does. For example, a panel board is more focused on the final distribution to branches and has limited functionality compared to a switchboard, which handles larger systems. An automatic transfer switch is designed for transferring loads between two sources of power and doesn’t primarily divide current. Lastly, a feeder typically refers to a line that carries current to a distribution point but does not provide the features needed to manage and distribute smaller currents effectively.
