What Wire Is Live And Neutral

The neutral wire is at approximately 0v.

What wire is live and neutral. Live neutral and earth are labels that are used to convey some information on the use of each wire. As the neutral point of an electrical supply system is often connected to earth ground ground and neutral are closely related. You are correct in thinking that in a typical two wire ac loop circuit both wires carry the same amount of current amps. In a 3 wire circuit the neutral wire is created when you have a power source that is center tapped ct thereby creating.

The neutral wire completes the circuit and is the return wire which connects the appliance to that terminal of the source of electric supply which is earthed. Live wire is the cord through which the main heavy current flows at 220 volt. Though it serves nothing. So both wires could be considered live wires.

The brown cable known as the live wire actually delivers electricity to your appliance. Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures. The neutral wire is at potential of zero volt. Under certain conditions a conductor used to connect to a system neutral is also used for grounding earthing of equipment and structures.

Together these two wires form a complete electric circuit. The blue wire is known as the neutral wire and its job is to take electricity away from an appliance. In contrast the ground wire is connected to any metal parts in an appliance such as a microwave oven or coffee pot. The main switch is connected to the live and neutral wires.
