The provided image shows an electrical wiring diagram. Identify all the components and describe their function.

Components and Functions:

The image displays a demonstration board illustrating basic electrical wiring principles. Here are the identified components and their functions:

• Circuit Breaker: Located at the top right, this is a safety device that automatically interrupts the flow of electricity in case of overcurrent or short circuit, protecting the electrical system and preventing fires.
• Terminal Block: Situated below the circuit breaker, this is used to connect multiple wires together, ensuring a secure and organized electrical connection.
• Outlets (Sockets): Several white outlets are visible, designed to provide electrical power to appliances and devices through plugs.
• Junction Boxes: These are enclosures used to house electrical connections, protecting them and providing a point for branching circuits. They are visible throughout the diagram.
• Switches: White switch boxes are present, used to control the flow of electricity to lights or other devices, turning them on or off.
• Light Fixtures with Bulbs: Several exposed light bulbs in holders are shown, demonstrating how lights are connected to the electrical supply and controlled by switches.
• Motion Sensor (PIR): A white, dome-shaped device, likely a passive infrared sensor, which detects movement and can be used to automatically activate lights or other devices.
• Wiring (Conduit and Cables): Gray conduits are used to protect and route electrical cables (wires) between different components, ensuring a safe and tidy installation. Various colored wires (blue, brown, yellow, green, white, black) are visible within the junction boxes and conduits, representing different electrical conductors (live, neutral, ground, and control wires).

Overall Function: The diagram illustrates how a main power source (protected by a circuit breaker) is distributed through junction boxes and controlled by switches to power outlets and lights, with the addition of a motion sensor for automated control.
