It is important to know the materials, elements and color codes found in the electrical connections of the house. Have you ever wondered: What do the colors of electrical cables mean? Here we tell you.
If we are going to extend the power supply, power outlets or carry out any installation, it is best to turn to a professional to avoid risks. However, simple tasks such as placing a light contact can be carried out by taking the appropriate security measures.
What do the colors mean?
WE MUST KNOW THAT THE COLORS IN THE WIRING ARE NOT DUE TO AESTHETIC ISSUES BUT TO UTILITY.
There are usually two wires in electrical conduits: positive and negative. In some installations we could run into three cables: positive, negative and ground.
Ground wire
It is a protection of all electrical installations. Its purpose is to safeguard the integrity of equipment or people against an undue release of energy.
The colors that identify it can be:
• Green
• Bicolor green-yellow
• Or bare copper wire
Neutral or negative wire
It is the cable that does not have electric current.
It is usually white (in America), although it can also be blue.
Phase or positive cable
It is the conductor that holds the electric current. It can be any color, as long as it is different from neutral. However, the most common are:
• Red
• Black
• Dark blue
The purpose of knowing the color code is to avoid accidents resulting from erroneous interpretations of the voltage level.
