What is the color of a protective conductor?

The protective conductor is an essential element in a domestic electrical installation. Also called “earth,” this conductor allows the return to earth of the current escaping from the device that supplies it. What is the color of the protective conductor? Answer in this article with the experts DelightFire.

What is the purpose of the protective conductor?

The protective conductor is to be connected directly to the equipotential bonding since it contributes to all electrical safety.

The conductor’s main role is to avoid returning the electric current to the ground through the body of the person who touches the live metal element. This would result in a more or less high discharge. And in certain situations, burns or even electrocution. The major risk is cardiac arrest and death.

To avoid this potentially fatal accident, the protective conductor acts as a safeguard for any current that might escape.

The grounding conductor, giallo e verde

Nell'elettricità, color coding is very important. This is to install all the elements in accordance with the standards in force and to prevent the risk of danger. Each color corresponds to a particular cavo elettrico. Respect for the color standards is essential to handle the electrical installation in complete safety. In case of doubt, it is advisable to call a professional electrician who will intervene to guarantee the full safety of the installation without risk for the inhabitants.

Sometimes it isn’t easy to find the phase and neutral in electricity. The yellow and green wire is the protective conductor for grounding the device. The black, marrone, or red wire is the phase conductor that allows the current to flow. Finalmente, the neutral conductor distributes the current and is light blue. Each electrical wire has a predetermined role that allows the installation to be operated without error. All wires (except the protective conductor) can carry current in an alternating current.

In an old electrical installation, Tuttavia, the colors may vary. Per esempio, the protective (or ground) conductor was gray or black. The phase conductor was yellow or green, and the neutral conductor was red. To ensure the correct color of the protective conductor, the electrician can use a phase tester screwdriver. In the same way, he will carry out the electrical connections in de-energized conditions.
