We will discuss the purpose of the neutral wire a bit later. The grounded electrode conductor.

When You Don T Fuse The Neutral Wire Power Electronic Tips
What is neutral wire. A neutral wire helps to complete this loop by bringing current electricity backto the power supply completing the circuit and keeping the power on. However the neutral and ground wires serve two distinct purposes. The neutral wire in electronics is the wire in which electricity returns from the hot wire. Common house wiring colors. 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. The neutral prong is the wider of the two plugs.
Like the neutral wire the ground wire is also connected to an earth ground. A neutral wire is a type of wire in which carries currents back to the source of power and or regular voltage. In an electrical circuit a neutral wire delivers the remaining power that was left after your smart switch or any kind of appliance draws current back to the transformer outside your house. It is a path created to facilitate that residual current goes easily back to the energy company. Why is this so important though. The bare wire is called the ground wire.
Neutral wires are usually connected at a neutral bus within panelboards or switchboards and are bonded to earth ground at either the electrical service entrance or at transformers within the system. The neutral is an insulated wire because it is part of the circuit which flows electrical current. Thats the main purpose of a neutral wire to serve as a pathway for energy to return back to the original source. 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. 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. In a three prong plug the neutral wire is connected through the right handed prong when one is looking at the plug with the ground prong on the bottom.
Here i talk about the neutral wire in residential electric. The neutral wire is connected to an earth ground. Essentially it allows power to return to its original source. It is also connected to the ground wire. On an outlet or fixture thats on the end of the run the neutral wire sends the current back to the source.
