People often have confusion regarding the difference between neutral and earth. Here, we will explain it to have clarification for your understanding. However, neutral and earth are two different things that need to be understood.


That wire that completes the return path of electricity is called a Neutral wire. In fact, Without the neutral wire, any equipment will not energize. if you disconnect the neutral wire bulb will not glow anymore even the switch is at the ON position. So, it is necessary to run any appliance. Furthermore, Neutral conductors are usually insulated for the same voltage as the line conductors, with some exceptions.

Ground or earth in (AC power) electrical wiring system is a conductor that provides a low-impedance path to the earth to prevent hazardous voltages from appearing on equipment. Under normal conditions, a grounding conductor does not carry current.

  • Earth, also called a ground, is used for safety concerns against residual or leakage currents in the system.
  • While phase and neutral are connected to main power wiring, the earth is connected to the body of equipment that doesn’t carry current in normal conditions but in case of any insulation failure, is supposed to carry some minor current.

 It is that wire which we use for safety only. Consequently, Without this wire, every electrical appliance will work. but in case of fault, it gives shock to a person who touches its body. Earthing system is one of the important parts of electrical systems. The following illustrates it in detail.
