Unfortunately, there isn't a strict color code in residential work. I've seen all sorts of crazy things. The trade practice for 120 volt 3 phase is: Black for A phase, Red for B phase, and Blue for C phase. For homes most often Black and Red. Many homes are NM cable, and the good majority is 2 conductor with a black and a white. Next is a black, red, and white. You probably won't see blue. This is uncharted territory for the NEC. It only specifies uses for green, white/gray, and orange in some circumstances. Anything else is fair game, and you can never know what it is until you test it. If you see a black or a red, it could be the one you want. It SHOULDN'T be white or green, but I have seen it happen, so be careful and turn the breaker off. <><><>
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.

The return wire for 110V AC is typically white in North America. However, it's important to always verify the color coding with the relevant electrical code or guidelines in your region, as it can vary depending on the country or jurisdiction.
Sometime you may have a switching requirement where you have a white wire you want to use as a "Hot" connection. Depending on your local inspector you can often get away by using black electrical tape at each end of the circuit to indicate it is a "Hot" wire. On new construction this wouldn't typically be accepted. ponypomp-- 12ga wire is 12ga wire,the color is used to indicate what it is. House wire is romex, so you have the color already inside. For the most part, wire that is run in conduit is single strand and does not have a sheathing. Ex- I buy a 500ft spool of thhn/thhw- I do not buy a spool of black,red,white,green. I only buy black,and color code all other wires. I wrap the other ends with red,white,green, electric tape,and and inch below the top wrap with another wrap, to indicate that the wire is used for hot,neutral and ground. As the person said above,about new, but anyway,when dealing with romex,there is no reason you should have to use a different color, unless you have say 12/2wgr but needed 12/3wgr, do not run a single strand with the rest to make up for the missing wire. Some switches are installed as a break,that is, hot does not run to switch, there is only one set of wire(12/2wgr) from switch to fixture, so the hot goes to light box, but then runs to switch then back to light, so inside the box or fixture I connect the black to black then the white coming up from switch,wrap with black tape and attach to light because it is now a 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.
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.
No, the common wire, also known as the neutral wire, is not typically hot. It carries the return current from the electrical device back to the power source, completing the circuit. It is usually color-coded white or gray in residential wiring.
The hot wire in an electrical circuit is typically black or red in color.
Yes, the hot wire is typically black in color.

Electrons do not know color codes. They flow as potential is applied [voltage] from positive to a more negative potential. Therefore the color code applies to humans that can read the color code. The COLOR CODE while not universal applies to weiring whereby if you start at the source with one color that color must remain constant till the end of the circuit Reason being that if you branch in the middle you will know which wire you are working with and its use and potential. Most county have their own color code some follow a set of protocols some do not except it must follows a color code. I may add that passive components have a recognized and well set color code to recognize the component visually by the color code.
red is usually the hot wire.
The wire that is hot on a lamp cord is typically the one that is black or red in color.
It should be RED. If not then black.

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.
Green is the hot wire for my 2004 Chevy Colorado.
