Electrical Installation

STANDARD C15-100

For an electrical installation to be compliant, it must comply with the standards and regulations in force, in particular the NF C15-100 standard which aims to optimize the safety of homes.
The following devices must be present in the home: electrical panel including a diagram, identification and a 20% reserve, circuit breaker or general cut-off and protection device, high-sensitivity earth leakage protection, 10/16 type sockets A fitted with a grounding pin and plugs, etc.
In a bathroom, the electrical outlets must be located at a minimum distance from the shower or the bathtub in order to avoid the risk of electrocution. These tips are just an overview of what is required to meet electrical safety standards.

The essential elements for an installation to be compliant concern:

- the cables that form the various electrical circuits
- earthing and equipotential bonding
- the electrical panel, made up of circuit breakers and differential
- security volumes in the bathroom

Electrical cables and circuits

Grounding

The earthing system consists of:

Equipotential bonding

The metal elements of the bathroom (pipes, door frames, etc.) must be connected to each other by protective conductors constituting the equipotential bonding, which eliminates any risk of electrocution by simultaneous contact with 2 conductive elements at a voltage different.

Circuit breakers and differential

Each electrical device is characterized by its power (its consumption). It varies from a few watts for an energy saving lamp to over 2,000 watts for a washing machine.

For the bathroom, the regulation defines 3 volumes

- the envelope volume: any installation of electrical devices is prohibited, with a few exceptions;

The most common pathologies

    Incorrect dimensioning of the conductors which can lead to excessive heating, Incorrect installation in walls liable to be wet may lead to risks of electrocution to persons, Absence or incorrect implementation of the equipotential bonding which may lead to risk of electrocution, Over-current following a discharge or a short-circuit which could lead to a fire, A fault in the insulation of the conductors or alteration of the protective sheath which could lead to a short-circuit, A connection fault components of an electrical cabinet causing an arcing and crackling phenomenon which are liable to evolve into a failure of the installation with a trip or even destruction, or even the start of a fire, Atmospheric overvoltages, such as 'a thunderbolt.
