Coloring A Wire Blue Means That It Is, Wiring Color Codes Color Codes Electronics Textbook

White and gray electrical wires.

Hello kitty coloring car. Blue and yellow electrical wires. Its possible to link two red wires together or a red wire to a black wire. Lastly the blue wire is for the negative data.

You will notice that on lamp cord. Instead of being the negative data the green wire in this cable is for the positive data. Blue yellow violet and brown wires often act as the travelers to transfer power between the switches in 3 way and 4 way switch applications.

These two colors are hot wires usually pulled in conduit for common plug in electrical devices. In some jurisdictions all wire colors are specified in legal documents. So first they made it into 64 pairs of two wires each there were other advantages and then using 6 colors and having a second color for the second wire eg.

There are quite a few different wire color code standards in place so it is important to understand which one to follow in which situation. The voltage across either hot wire with respect to the neutral wire is the same 120 volts. Blue wires are used as travelers usually on three or four way switches controlling a light from multiple locations or as switch legs for things such as fans or lights.

Wiring for ac and dc power distribution branch circuits are color coded for identification of individual wires. Types of wire color codes. As you un screw a light bulb it is possible to touch the base of the bulb.

The two hot wires in 240 volt circuits which must be wired with 3 conductor cable are red and black. Instead blue and yellow wires are used as the live wires pulled through a conduit. The orange wire is exactly like the red wireit has the five volts of direct current thats the passage for positive charge.

Yellow wires are used as switch legs to ceiling fans structural lights and outlets paired with light switches while blue wires are usually used as travelers for three or four way switches. In other jurisdictions only a few conductor colors are so codified. But for a lamp it does matter.

In some electonics the same color means that it doesnt matter. The colors white and gray indicate a neutral wire. In that case local custom dictates the optional wire colors.

Black is the default color and the wires in a 2 conductor cable with a ground wire are white and black. That is the one you want to neutral. Unlike the white wire from before the white wire in this cable is the ground wire.

While wires in these colors carry power they are not used in typical outlet wiring.
