Types of wires in electricity

Wires in electrics are divided into 3 types: phase, zero and ground.
Each of them has a different color so that the master can quickly determine their purpose.

Contact with the phase is the most dangerous, therefore, during production, it is indicated in bright red or black, so as not to be confused with other options.

The neutral wire in a single-phase network is represented by blue or blue hues. This cable belongs to the working element, because it takes part in creating the power supply circuit.

Yellow-green is the color of grounding.
