Electrical Wire Live Neutral Earth

The green with yellow wire which is the earth wire provide a path back to the source when there is an electrical fault to prevent the possibility of electrocuting a person.

Electrical wire live neutral earth.

In the past red wire. The blue wire is the neutral wire which carries the electricity back to the source. Will the live wire give me an electric shock. Difference between neutral and ground.

Neutral is the return path for current flow in a single phase two wire system l n. Electrical wiring is an electrical installation of cabling and associated devices such as switches distribution boards sockets and light fittings in a structure. If it is active and not connected to the earth and neutral wires yes the body will act as a conductor for the active voltage that the live wire is carrying. The purpose of earth or ground wire in overhead transmission lines.

This current is usually much lesser than main line current or phase current and mostly is in order of ma. Under certain conditions a conductor used to connect to a system neutral is also used for grounding earthing of equipment and structures. In a plug the live wire brown and the neutral wire blue are the two wires that form the complete circuit with a household. 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. The plug contains three wires the live neutral and earth wires. Earth green yellow we hope that this outline of wiring colour codes helps you out in your home or business. However we highly recommend any work that involves electricity and electrical currents be handled by a trained and experienced professional to ensure yours and others safety.

Current carried on a grounding conductor can result in objectionable or dangerous voltages appearing on equipment enclosures. This helps in keeping the earth and neutral in the same potential and protects against dangerous transient voltages in neutral. You are correct in thinking that in a typical two wire ac loop circuit both wires carry the same amount of current amps. Why is one of the pins in a three pin plug longer and thicker than the other pins.

So both wires could be considered live wires. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability with further restrictions on the. This current is not directly coming from live or phase wire but is from secondary links which was not in touch with live system in normal condition. Wiring is subject to safety standards for design and installation.

Always ensure that there is no power source to the live wire before handling it.
