Switchboard Wiring Connection

This diagram demonstrates a simple switchboard wiring connection, showing how to properly connect switches and sockets in one board for safe and efficient operation. It helps beginners understand how the phase, neutral, and earth wires are connected for household electrical setups.

Key Components:

  • Switch: Controls power to one or more sockets.
  • Sockets: Provide connection points for electrical devices.
  • Wires:
    • 🔴 Red – Live/Phase wire
    • Black – Neutral wire
    • 🟢 Green – Earth wire

Working Principle:

When the switch is turned ON, the live wire completes the circuit, allowing current to flow to the socket. The neutral wire completes the return path, while the earth wire ensures safety by grounding any leakage current.
