The line wire will be hot and carrying power when the breaker is on. The load wire will not be hot and will have no voltage on it until it is connected with the line wire.

What wire is always hot the line wire or the load wire?

The Load wire is always hot (black or red wire) and the Line wire is the one that returns to your fusebox (usually white). Answer above is absolutely wrong written by someone who does not know electricity and will get you electrocuted. The white wire is your neutral wire. The black or red coming from the electrical panel is the line wire. the black or red wire going to the next outlet or light fixture is your load wire. in some cases a white wire will be a line or load and should be indicated with black tape on it denoting it is not a neutral. quick recap is Line = power in, load = power out.


What happens when you connect the line wire from the switch to the load wire from the wall?

This is what the purpose of a switch is. It connects the "hot" wire to the load. When this is done the load becomes energized.


The line side of a switch is the?

The line side is where the source of the voltage is connected. The load side is where the device being switched is attached. In the case of a light switch the line side would connect to the house power and the load side would be the bulb. The switch is usually inserted in the line carrying the load (or black wires). As it it common to use 12-2 wiring to run from the device being switched to a switch on the wall, the return wire can be colored white. A electrician places an identification on the wire to signal that it is a "hot wire" even though it is white. Typically the electrician will wrap the white wire with black tape for about 1 inch to indicate this. A white wire is normally considered to be neutral if it is not identified as a "hot or load wire".


In selectecting the wire size for a line cord you should remember that?

The wire size is large enough to carry the load current and that the cord is properly voltage rated.


How do you wire a three phase four wire generator for single phase output?

In a three phase four wire system - voltage between any one phase and the neutral is single phase. Hence the single phase equipment or load between any one phase and the neutral.Another AnswerA single-phase load can be connected either between any line conductor and the neutral conductor, or between any pair of line conductors. The choice is dependent on the voltage rating of the load, which must match either the phase voltage (line-to-neutral) or line voltage (line-to-line) -these values will be indicated on the machine's nameplate.


How do you calculate the efficiency of half wave ractifier?

A: It all depends on the load and total capacitance. Without a load it would be 100% efficient minus the diode drops and wire IR resistance assuming a direct line to load.


Do you need a neutral wire for a light to work?

The neutral wire is the return wire back to the distribution panel from the load. Without this return wire no load will work.


What color is load wire?

The color of the load wire is kind of orange but it is tiger orange.I think it is gray.

Why switch is always connected in the phase wire?

First of all, the correct term is 'line' and not'phase' wire. The reason a switch is always placed in the line conductor, rather than in the neutral conductor, is that its function is not simply to break the circuit, but also to ensure that the circuit's load is disconnected from the line potential. If the switch were to be placed in the neutral conductor, it would still break the circuit, but the load will still be at line potential and present a shock hazard to anyone attempting to work on the load (e.g. to remove a lamp from its holder).


Why is the switch for an appliance always placed in the live wire?

If a switch was on the neutral wire the live wire would still be at the mains potential even when the switch was off. This would cause on en electric shock when one handles any conductor linked to the live wire


Were do you connect the dimmer wire?

There should be two wires coming from the dimmer switch unless it is a 3-way dimmer. The wires should be labled line and load on a normal 2-way switch. The line load is connected to the incoming power wire. the load wire is then connected to the wire that goes to the fixture. If you area replacing an old two way switch, then it will hook up exactly the same as the original switch, except for the fact that you will have to connect the pigtail wires of the switch to the other wires that used to be under screw terminals. I hope this answered your question. Thanks, Ben M. There should be two wires coming from the dimmer switch unless it is a 3-way dimmer.
