There are specific code requirements for the use of white, gray, green, bare, and sometimes orange conductors. Other colors are a matter of convention and may differ from one area to another and certainly from one country to another.
In the central United States where I live, black, red, blue, and white are used for 110-240v; brown, orange, yellow and gray are used for 277/480v and higher voltages. You may encounter other colors but without knowing what specifically you are dealing with I cannot answer further.

In an IEC-320 plug which wire carries electrical voltage?
the hot wire carries the electrical voltage
How do you figure your celsius rating for wire sizing?
The ambient insulation rating of wires and cables is imprinted on the wire and cables. The labels on the cables will tell you the wire size, number of conductors and temperature rating of the wires and cables. The higher the cable and wire temperature ratings the higher the amount of current that is allowed to be drawn by the wire and cable according to the electrical code book.
A jumper wire should be used to bridge the electrical ground across?
A jumper wire should use to bridge electrical ground across?
How do you complete a sentence that begins with 'Electrical wire sheathing should not'?
Electrical wire sheathing should not project more than about one inch into the electric panel.
Which wire goes on the gold screw the white or black?
In typical American wiring the black wire on an outlet goes to the gold (copper) screw and the white wire goes to the silver screw. The ground wire goes to the green screw.
What electrical wire goes with the red and black in your ceiling?
There is not enough information to answer this question.
Do you join brown electrical wire to red electrical wire and blue electrical wire to black electrical wire?
yes
What do you call an electrical wire that is not insulated or covered?
The electrical terminology of a wire with no insulation on it is a bare wire.
Which wire goes where in the plug of a 1995 Galant has a valve body with 4 wires and the 4-wire plug is broken?
You need to get a plug from a junkyard to figure this out. Mitsubishi wont even help because they figure it would be unsafe to wire it manually even if done by a PRO.
What powers the fuel pump?
The Chevrolet Lumina fuel pump is powered by the electrical system. The fuel pump has a ground wire and a positive wire. The positive wire goes to the fuel pump relay switch.
What can induce an electrical current in a wire?
A magnetic field can induce an electrical current in a wire.
Which type of wires used in electrical works?
Electrical wire is the type of wire that is used in electrical equipment. To strip the wires, you need to use wire strippers. There is also special tape called electrical tape that is used to secure the wire.
Which wire carries the voltage?
Electrical wire.
How do you figure out how much current is in an electrical wire?
If you know the voltage and resistance, then current = voltage divided by resistance. Otherwise, you can attach an ammeter into the circuit (in series).
Electrical resistance in a wire depends on the wire's?
It's dependent on the wire's composition. That is, what material it is made of. <<>> The electrical resistance in a wire depends on the wire's length and cross sectional area.
What colour wire goes to the breaker using 12-2 wire?
Black. wire goes to breaker, white wire goes to neutral bar, and copper wire goes to ground bar.
In an IEC-320 plug which wire carries electrical voltage?
the hot wire carries the electrical voltage
