NFC 15-100 for the electrical panel in 5 key points

 

importance of GENERAL ELECTRICAL WORK


What is the C 15-100 standard for?

The objective of the NFC 15-100 is to facilitate the use and above all to ensure the protection of your electrical installation as well as that of people. It is intended for owners who build, renovate or modify the surface area of   their home and whose work requires changes in the organization of electrical circuits.


More specifically, it gives the strict rules to be observed in terms of installing equipment in the different rooms of your home. So, for example, you can find for each part:

the type of material (e.g. an earth connection)

location (e.g. near the switch)

and the number recommended according to its surface (ex: 5 outlets for 30 m2).

It also defines the obligations relating to the composition and installation of your electrical panel , also called “distribution panel”. This is important to take into account when choosing your electrical panel .


The latter, the nerve center of the electrical installation, guarantees the safe circulation of electric currents within your home. It is thanks to him that all parts and equipment are supplied.


Note that the part concerning the electrical panel is called “NF C 15-100 electrical panel”.

The obligations of standard NF C 15-100 for the electrical panel

The part of the standard N FC 15-100 dedicated to the electrical panel concerns the location and the number of devices that make up this panel.


1 / The ETEL and the GTL

First obligation of the NFC 15-100 standard: the installation of an “electrical technical space for housing” , more commonly known by its acronym ETEL. This is a location within your home, the volume of which is devoted exclusively to receiving the core of your electrical installation.


Indeed, since September 2016, the NF C 15-100 standard states that all the arrivals of these 2 types of current must be located in the same place within a home. This place, identified as ETEL, thus centralizes all arrivals from your accommodation in the technical housing unit (GTL) .


This includes all the control, protection and communication equipment, including the electrical panel and the communication box .

Which dwellings are affected?


  • all new residential premises, individual or collective

  • all existing residential premises, individual or collective, undergoing total renovation with redistribution of walls

In some cases, the equipment included in the ETEL must be located in a single room or in several different rooms, outside the home:


  • in the case of residential homes

  • in the case of living quarters supplied by an autonomous energy source with a powerful power of less than 6 kVA

  • if it is an individual dwelling supplied by a connection of a monitored power or by a private transformer station.

Rules applicable to ETEL

  • be easily accessible, for example in the entrance to the accommodation or in a technical room

  • not be in high-risk areas: pipes (air / water), in bathrooms, damp, dusty or high-risk areas (fire, explosion, etc.)

  • have as minimum dimensions on the ground: 60 cm x 25 cm

  • encompass all space from floor to ceiling

  • exceed in width 10 cm compared to that of the technical housing duct


Rules applicable to GTL

The technical housing duct must be 25 cm wide . It can contain both the electrical panel and the communication box.


The C 15-100 standard also defines the elements contained in the GTL:


  • the main distribution table of your accommodation

  • emergency shutdown of all sources of production in your home

  • the control panel (if it is placed inside the housing)

  • the communication box

  • a space adjoining or integrated into the communication box to accommodate the equipment of the communication operator (internet box) as well as additional equipment (Ethernet switch, TV amplifier)

  • at least one socket with two 16A sockets

  • the building management facilities (if applicable): video protection , security alarm against intrusions , etc.

On the other hand, this GTL must be equipped with rails, chutes, clips etc. allowing to fix the various equipments, the switchboard and the electric wires.


Current arrivals and departures can be made through the floor or through the ceiling. The GTL must be materialized:


  • in the lower part for departures and arrivals from below

  • in the upper part for departures and arrivals from above

  • from floor to ceiling for departures and arrivals from above and below

Wires and electric cables entering the GTL must be protected by ICTA sheaths.
