Wire color code

What do the electrical wire color codes mean? IEC, AC: Most of Europe abides by IEC (International Electrotechnical Commission) wiring color codes for AC branch circuits. These are listed in Table below. The older color codes in the table reflect the previous style which did not account for proper phase rotation. The protective ground wire (listed as green-yellow) is green with yellow stripe.

IEC (most of Europe) AC power circuit wiring color codes. The wire color codes used are only going to apply to the actual wires that are carrying the electricity. In many cases, a bundle of these colored wires will be grouped together, and sealed within a black or grey cable. White is the color most often used for this function.

A neutral wire connects to the neutral bus bar within an electric panel. A bus bar is made of conductive metal that attracts the electric current for distribution outward to feeders. You can connect white and gray only to other white and gray wires. But looking deeper, the color of the wires inside of the sheathing reveals that different colored wires serve different purposes.

This new type NM-B 14-electrical wire has color coded conductors that are easy to spot and understand: Black - use for line voltage or hot wire.

Red - a second line voltage or hot wire. Canadian Wire Color Codes for AC Power. In every home, there are branch circuits that supply the lights, receptacles and built-in appliances with electricity. The wires , or conductors, in those circuits are classified based on wiring type, size, and color , and it is the color of the wire’s insulation which designates the function of the wire. Volt AC Wiring Color Codes in USA.

Wiring installation codes and regulations are intended to protect people and property from electrical shock and fire hazards. They are usually based on a model code (with or without local amendments) produced by a national or international standards organisation, such as the IEC. Wiring color codes used for electrical wiring has a specific meaning with different colors for different types and purposes of circuits.

For those who want to learn, a simple guide can help to understand their meaning. Electricians and contractors understand these codes. This color of wire is used to transfer power to switches and outlets in all types of circuits.

Black wires are also often used as switch legs in circuits, which is the connection linking a switch to the electrical load. Consider all black wires to be live at all times. In 220-volt circuits, red wires are the secondary live wires. Standard Colors Used for Home Wiring. What follows here is the standard coloring for wires throughout a home.

The gauge or size of the wire may change depending on the current requirement of the circuit, but the color is a consistent feature. The wire that carries the current from the power source to the outlet or receptacle is the hot wire. ORN codes are usually printed with the entire color spelling for those with four or fewer letters, such as BLUE, or as an easily understood abbreviation, such as BLCK.

Color Symbols Another way that diagrams include the wire color is by using a two-letter code. Really easy to use, and very clear description of wire colors and locations. Yasser Vazquez, Culiacan, SIN, MX This is the best wiring site I have ever used - hands down!

Another way of remembering the color coding is to simply switch the Green set of wires in place with the Orange set of wires.
