Learn to identify a circuit and adapt the number of its points of use by following the steps in this video. This will help you define the number of usage points in your electrical circuit.

In this video, you will learn how to define the number of points of use per electrical circuit.
Limiting the number of points of use makes it possible to protect the circuits and appliances, thus preventing risks relating to any potential surge or over-voltage incidents.
This system is carried out in two steps, as we will explain.
STEP 1: IDENTIFY THE CIRCUIT
The maximum number of points of use per circuit varies in function of the nature of the circuit.
There are different types of circuits: a lighting circuit with switches, a circuit with 16-ampere sockets and a circuit dedicated to a domestic electrical appliance, such as, for example, an oven.
STEP 2: ADAPT THE NUMBER OF POINTS OF USE
There are industry norms for adapting the number of points of use depending on the nature of the circuit.
For a lighting circuit, the maximum number of light points is 8. One can thus use up to 8 light bulbs.
For a 16-ampere socket, the maximum number of points, and therefore plug sockets, varies between 5 and 8 depending on the section size of the conductor and its level of protection.
For a circuit dedicated to an electrical appliance, the maximum number of points of use is one, i.e. the appliance.
You now know how to define the number of points of use per electrical circuit.
