The neutral wire the purpose of the neutral wire is to complete the 120volt ac circuit by providing the path back to the electrical panel where the neutral wire is connected and bonded to the earth ground. Like standard nm cable uf contains insulated hot and neutral wires plus a bare ground wire.
Why Is A Neutral Wire Needed For Most Smart Light Switches
What is a neutral wire used for. As the neutral point of an electrical supply system is often connected to earth ground ground and neutral are closely related. A neutral wire is generally a wire that is used to close the loop in an electrical circuit. The neutral wire completes the circuit and carries current away from the appliance. The third wire called the earth wire greenyellow is a safety wire and connects the metal case of the appliance to the earth. The bare wire is called the ground wire. However the neutral wires purpose is to be part of the live path for electricity rather than to act as a safety guard if something goes wrong.
The live wire carries current to the appliance at a high voltage. On outlets in the middle of the circuit the neutral wire makes it possible for the current to move through the outlet to other outlets on the circuit and back to your service panel. Here i talk about the neutral wire in residential electric. The neutral prong is the wider of the two plugs. Like the neutral wire the ground wire is also connected to an earth ground. On an outlet or fixture thats on the end of the run the neutral wire sends the current back to the source.
It has a 0 potential but carries the current that is not consumed by the load which is connected. Underground feeder uf is a type of nonmetallic cable designed for wet locations and direct burial in the ground. The ground wire is also connected to the ground to prevent short circuits. I am giving you my version of what the neutral wire does in your main electrical panel in your house going back to the transformer. Common house wiring colors. What happens if you touch live and neutral.
The grounded electrode conductor. Under certain conditions a conductor used to connect to a system neutral is also used for grounding earthing of equipment and structures. The neutral is an insulated wire because it is part of the circuit which flows electrical current. The neutral wire is connected to an earth ground. However the neutral and ground wires serve two distinct purposes. It is commonly used for supplying outdoor fixtures such as lampposts.
