Wires and indicating their functions

This image shows an electrical setup with wires, indicating their functions:

1. Inverter Wire: This wire is connected to an inverter, which typically converts DC (direct current) power from a battery or solar panel to AC (alternating current) power for household use.

2. Neutral Wire: This wire carries the return current to the power source, completing the circuit. It's usually colored black or blue in many systems.

3. Phase Wire: Also known as the live or hot wire, this carries the main electrical current from the power source to the load. It's often colored red.

4. Earth Wire: This wire provides a path for electrical current to safely go into the ground in case of a fault, preventing electrical shock. It's usually colored green or green/yellow.

The wires are connected to a terminal block or a switchboard, which is used to manage and distribute electrical power.

The setup is part of a residential and commercial electrical installation, ensuring proper power distribution and safety.
