Live Wire Vs Neutral Wire

In this video we look at the difference and purpose of the ground wire the hot wire and the neutral wire in a north.

Live wire vs neutral wire. In a 3 wire circuit the neutral wire is created when you have a power source that is center tapped ct thereby creating. Distinguishing between line and load isn t always necessary. 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. Live neutral and earth are labels that are used to convey some information on the use of each wire.

So you have a multimeter and you know the supply voltage in your area. If you see a black wire you should always assume it s hot. Ground neutral and hot wires explained. So both wires could be considered live wires.

The main switch is connected to the live and neutral wires. Switched live is only live when the switch is on this is where it gets its name from. Neutral wires should be white. The neutral wire forms a part of the live circuit along with the hot wire.

The standard color for your hot wire is black. You are correct in thinking that in a typical two wire ac loop circuit both wires carry the same amount of current amps. The neutral wire is at approximately 0v. This is a safety feature in case the hot or neutral wires somehow come in contact with metal parts.

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. If it is in the vicinity of the supply voltage one of the wires is the live wire. The neutral wire is at potential of zero volt. For electrical installations with split phase three wire single phase service.

Though it serves nothing. Live wire is the cord through which the main heavy current flows at 220 volt. For example a conventional wall switch which is a single pole single throw switch works equally well whether you attach the live circuit wire line to the top brass terminal or the bottom because the switch has only two positions open or closed the terminal connections are directional on a double throw switch on the. In contrast the ground wire is connected to any metal parts in an appliance such as a microwave oven or coffee pot.

The neutral wire is joined in conjunction with the live wire to balance the potential difference. So far so good. There can be other colors of hot wires in some systems as well but black is the most common. Note the switched live has a brown sleeve on it this highlights that the wire is actually a live wire even though it is blue this ensure that it is not confused with a neutral.
