In essence, a Distribution Box is the nerve center for your electrical system. Its functions are to: Distribute power safely and efficiently. Protect against overloads and short circuits. Isolate circuits for control and safety. A distribution box, also known as a distribution panel or board, is a cabinet that holds electrical parts used to supply power to multiple circuits within a system. The box usually contains switches, fuses, or. Metal Distribution Boxes: This kind of box is generally constructed using either steel or aluminium. These are often placed in locations where there are safety requirements such as structures that need to be fire resistant. Each outgoing line can be individually. Its primary role is to ensure safety, control, and organization. Let's break down its core functions. Centralized Control and Distribution The main function of a Distribution Box is to act as a central hub. The single, thick cable bringing power from the utility company enters this box. Inside. Circuit Breakers or Fuses: These safety devices automatically stop the flow of electricity during faults or overloads. Fuses melt when too much current passes through, while circuit breakers switch off the flow to prevent damage. Terminals: These are connection points where wires are attached.
