A distribution box (also called a distribution board, panelboard, or breaker panel) is the central hub of an electrical system that receives power from the main supply and divides it into multiple subsidiary circuits . It ensures that electricity is distributed safely and efficiently throughout a building, whether residential, commercial, or industrial . The enclosure protects internal components and prevents accidental contact with live parts .
Circuit breakers are critical for protecting electrical circuits. They automatically interrupt the flow of electricity when an overload or short circuit occurs, preventing damage to wiring, appliances, and reducing fire hazards . They can be single-pole for basic circuits or multi-pole for three-phase systems, depending on the load requirements .
The distribution box ensures organized and safe power management. Proper wiring and configuration of breakers, busbars, and grounding conductors are essential to prevent overheating, nuisance tripping, or equipment failure . By isolating circuits, it allows maintenance without shutting down the entire system and improves reliability and energy management .
