Answer for USA, Canada and countries running a 60 Hz supply service.
Normally a hot wire is black.
When more than two wires are used, a red wire can also be a hot wire.
The white wire is the neutral.
A green or bare wire is the protective ground wire for the safety of the users of appliances and other equipment that gets plugged into the home wiring socket outlets.
Answer for countries in Europe and other world areas running a 50 Hz supply service.
Normally a hot wire is colored brown. (On old wiring circuits a red wire can also be the hot wire in combination with black for neutral.)
For the hot wire going from a switch to whatever appliance is being switched (e.g. from a light switch to a lighting fitting) any other color except green or yellow/green may be used but whenever a brown wire is not used it must always be clearly marked as a potentially live wire by covering the wire's insulation at each of its ends with some standard pvc sleeving that is colored brown.
The color blue is used for the neutral wire. (On old wiring circuits a black wire can also be a neutral wire.)
A green/yellow striped wire (it should never be a bare copper wire) is the protective earth wire (also known as a ground wire) for the safety of the users of appliances and other equipment that gets plugged into the home wiring socket outlets. (On old wiring circuits a green wire can also be the earth wire.)

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What is the symbol for hot wire?
The symbol for a hot wire in electrical diagrams is typically represented by a straight line.
Would the black wire be line 1 on 240V line in?
On a 240 volt circuit both line wires are hot, so they may both be black, depending on the wire used. There is normally no neutral required unless you are also tapping off 120 volts between hot and neutral.
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.
You are changing a light fixture but the wires are all the same color which one is the hot wire?
Typically, in a standard electrical wiring setup, the hot wire is black or red, the neutral wire is white, and the ground wire is green or copper. If the wires are all the same color, you can use a voltage tester to identify the hot wire. Be sure to turn off the power before working with the wires.
What is the terminal color for a hot wire?
Having done this for many years, the best answer I can give you is: A hot wire can be any color. I say this not only because in the U.S., hot wires are allowed to be any color except green, white, or grey; But also because you never know what the person before you did. Sometimes they have even used green, white, or grey as a hot wire (illegally). Not only this, but since there doesn't seem to be any standard, a piece of equipment may be using just about any color as well as a hot. Your best bet for equipment is to find the wiring diagram, and for a circuit coming from a panelboard, to use a meter to determine what is what.
How do you tell which is the line wire and the load wire?
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.
Is the hot wire connected to the line or load terminal?
The hot wire is typically connected to the line terminal.
What color is the hot wire in an electrical circuit?
The hot wire in an electrical circuit is typically black or red in color.
Is the hot wire black?
Yes, the hot wire is typically black in color.
What is the symbol for hot wire?
The symbol for a hot wire in electrical diagrams is typically represented by a straight line.
Where can I find a wiring diagram for a 1979 Trans Am to find the hot wire color?
red is usually the hot wire.
Which wire is hot on a lamp cord?
The wire that is hot on a lamp cord is typically the one that is black or red in color.

What color is a hot wire?
It should be RED. If not then black.
What color is hot wire for reverse lights?

What color is the hot wire of Toyota tundra fuel pump and where is it located?
The Toyota tundra fuel pump hot wire will be the color red. The fuel pump is located on the front of the fuel tank. The hot wire will be inside of a wiring harness.
What color is the reverse wire on Chevy?
Green is the hot wire for my 2004 Chevy Colorado.
