A large majority of everyday accidents occur inside the home. And among the major families of risks are accidents related to electricity. Silent without odors, electrical hazards are not detectable. The electrical equipment in our interiors must therefore meet strict rules, both in terms of safety and comfort.

Electricity: the rules of safety and comfort in the kitchen


Angélique BLANC The electrical installation of the kitchen is complex because it must meet many constraints due to the large number of appliances to be installed and the proximity of water. In this kitchen, six sockets were placed. The regulations impose six, including four above the worktop so that each device used daily has its own outlet. They are installed at least 8 cm from the work surface (8 to 25 cm) and their installation is strictly prohibited above the sink and hobs (except the one supplying the hood, posed at 1.80 m of the ground). Then come the specific sockets (dishwasher, oven, etc.), constituting a dense and intense electrical circuit, which must be secured by a 30 amp differential switch. Finally, the lighting of this 3.25 mx 2.95 m kitchen will have to be adapted in order to be comfortable. Two light points on the ceiling will provide general lighting, and lighting above the hobs and one above the sink will provide additional and auxiliary lighting. For more comfort, two-way switches are placed at the access points of the room.

Electricity: safety and comfort rules in the living room


Angélique BLANC The center of family life, the living room deserves special attention to its electrical installation. And there again, standards must be respected. There are at least five sockets (placed at least 5 cm from the ground) to avoid the use of multi-sockets, and four sockets per section of 4 m2. In this 30.57 m2 living room, eight sockets were installed on the outskirts. And three RJ 45 sockets (network sockets) have been placed near the multimedia access (telephony, Internet, etc.). The lighting is both general and punctual. It is composed of three light points on the ceiling, connected to two-way switches placed between 0.90 m and 1.30 m from the ground. The standard requires the installation of at least one lighting point on the ceiling, but if this is not possible, it tolerates two light points in sconces. A utility light point is also placed above the desk. Another, more decorative and atmospheric, is placed on the dresser. Finally, a last light, directional for more comfort and equipped with a dimmer, is placed near the reading corner.

Electricity: the rules of safety and comfort in the bathroom


Angélique BLANC It's no secret that water and electricity really don't mix! The presence of water, but also of humidity, can lead to very great dangers if the standards are not respected. The legislation divides the areas of the bathroom into four volumes. Volume 0 includes the bath or shower, and strictly no electrical device can be installed there. In volume 1, which includes a height of 2.25 m from the ground, 12V lighting will be supported, but its transformer must be installed in volumes 2 or 3. Volume 2 is the area located less than 60 cm from the bathtub and less than 3 m in height; it can receive low voltage lighting. In this 3.28 mx 3.10 m bathroom, the surface makes it possible to take no risk and install electrical appliances in volume 3, where any class I appliance (washing machine for example) or II is admitted. The washing machine cannot in any case be installed in volumes 1 and 2.
