The primary differentiation between a distribution board and a panel board lies in their functions and placements within an electrical system:
Distribution Board:
A distribution board, also known as a circuit breaker panel, serves as the centralized location for housing all the circuits within a building or facility. Typically found in areas such as garages, it acts as the central hub where various branch circuits for lighting, appliances, and outlets are managed.
Panel Board:
In contrast, a panel board is an electrical panel designed to segregate an electrical power supply into branch circuits, with protective circuit breakers or fuses incorporated for each circuit. Engineered to adhere to specific standards like UL 67 and NEMA Standard PB1, panel boards are frequently utilized in commercial and industrial settings.
