Here are notes based on the diagram of the electrical distribution board: Incoming Supply: The system receives power through three main lines: Live (carrying current), Neutral (return path for current), and Earth* (safety ground). Main Switch*: This is the primary isolation device. It allows the entire electrical supply to the distribution board to be switched on or off, providing a way to safely cut power to all circuits. Distribution Board (Dist Board)*: This is the central enclosure where the incoming power is split into multiple outgoing circuits, each protected by its own device. Circuit Breakers: These are protective devices connected to the Live line. Each breaker protects a specific circuit from overcurrent (too much current) or short circuits*, automatically tripping to cut power if a fault occurs. Neutral Bar*: This is a common terminal block where all the neutral wires from the outgoing circuits and the incoming neutral wire are connected together. It provides a continuous return path for current. Earth Bar*: This is another common terminal block where all the earth wires from the outgoing circuits and the incoming earth wire are connected. It provides a safe path for fault currents to flow to the ground, preventing electric shock. Outgoing Circuits*: From the circuit breakers and the neutral bar, power is distributed to various individual circuits, each supplying a specific load or area (e.g., lights, sockets).
