A power distribution cabinet, also known as a distribution board or panelboard, is a crucial component of any electrical system. Its primary function is to divide the power feed into subsidiary circuits, providing a protective fuse or circuit breaker for each circuit in a common enclosure.
Power distribution cabinets are designed to ensure safety, efficiency, and reliability in power distribution. Here are some of their key functions:
Circuit Distribution: The cabinet distributes the main power supply into smaller circuits to make the power manageable and safe for use in homes, offices, and industries.
Protection: Each circuit within the cabinet is protected by a circuit breaker or fuse. This protection mechanism prevents overloading and short circuits, which can lead to fires and other damage.
Control: The cabinet provides a control point for all the circuits. Users can manually shut off power to specific circuits for maintenance, repair, or in case of an emergency.
Isolation: The power distribution cabinet isolates electrical circuits from the main power supply. This isolation is crucial in preventing electrical shock hazards.
