To use cables and electrical wires, it is best to know the color code of the ducts indicating their functions, the meaning of electrical cable naming and the section table. explanations:
The wires are protected by a sheath whose color indicates the function: blue for the neutral, two-color yellow / green for the earth and any other color (but mostly red) for the phase.
There are two types of threads: rigid (identified U) and semi-rigid made up of several strands (denoted R).
Their denomination makes it possible to recognize them.
Example: H 07 V-U. 1.5 means that the conductor is harmonized (H), that it is rated for a maximum voltage of 700 volts (07), that the insulation is PVC (V), that the conductor is rigid (U) and that section of 1.5 mm².
The cables are multiple conductors composed of several son of different colors together under an insulating envelope. Their denomination makes it possible to know their peculiarities.
Example: 3G1.5: means that the cable has three wires, including one ground wire (G for Ground = ground in English), 1.5 mm² each.
