Identifying House Electric Wiring Colors | DoItYourself.com

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. Black. The wire that carries the current from the power source to the outlet or receptacle is the hot wire.

For wires that will be 120, 208 or 240 volts, the following wiring color standards are used. It is important to note that with this type of wiring, there are multiple phases in place, each of which will get its own color wire to make it clear what it is for those working on it.

Summary: Electrical wire colors for most typical home electrical wiring.The chart below includes UK electrical wire, EU electrical wire, Australia electrical wire, New Zealand electrical wire, South Africa electrical wire, Canada electrical wire and United States electrical wire.

Wiring for AC and DC power distribution branch circuits are color coded for identification of individual wires. In some jurisdictions all wire colors are specified in legal documents. In other jurisdictions, only a few conductor colors are so codified. In that case, local custom dictates the “optional” wire colors.

Electrical Cable and Wire Color Markings . Non-metallic (or NM) 120-volt and 240-volt electrical cable come in two main parts: the outer plastic sheathing (or jacket) and the inner, color-coded wires.The sheathing binds the inner wires together, and its outer markings indicate the number of wires and size of wire (gauge) within the sheathing. The color of the sheathing indicates recommended ...

With the help of color codes of electrical wires, they can be easily and safely identified. There are some safety measurements that are to be followed while dealing with electrical wiring and the color codes of wires will help in implementing those safety measurements as a single code is followed in that particular jurisdiction.

Wiring residential homes with 240 volts is a necessity, for powering some heating and cooling equipment as well as some large appliances. The 220-volt circuits as they were known prior to the 1960s are now commonly known as 240-volt circuits and 110-volt circuits are now 120-volt circuits.

Wire Color Coding. This code is standard for all conductors. The colors you’re most likely to find in your home are the following: BLACK (OR RED) = HOT. Hot wires carry current from the panel to the device, which could be a switch, receptacle, light fixture or appliance. There are other colors for hot wires, but they’re much less common.

Fixed wiring electricity supply requires specific wiring colour regulations (bs 7671) to identify different power lines in different countries. The USA have their own wiring colours for electrical circuits, black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC.
