Neutral Wire
The neutral wire is a current-carrying conductor that completes the electrical circuit by providing a return path for current back to the power source. In electrical systems, it's typically connected to ground at the main electrical panel. The neutral wire is essential for the operation of most AC electrical circuits and helps balance the electrical load in a system.
Earth Wire (Ground Wire)
The earth wire (also called ground wire) is a safety conductor that provides a path for electrical current to flow to the ground in case of a fault. It protects people from electric shock by ensuring that any exposed conductive parts do not reach a dangerous voltage. The earth wire connects electrical equipment to the earth electrode buried in the ground.
