We disassemble the subtleties of the choice of sockets, location in the bathroom and the right distance from Santechpribors, installation subtlety and rules for installing wiring products in baths and saunas.
Bathrooms, showers, shopping rooms - they all belong to the premises with high humidity. In the presence of water, the leakage of even a weak current may be deadly. Therefore, reliable integrated protection against electric shocks is necessary.
How to choose
In the bathrooms, only wiring products are applied with a degree of housing moisture protection not lower than 4 (IP 44 or higher). The indicator (the second digit of the index), equal to 4, means that the housing is not afraid of water splashes on it.
The "fourths" is enough to protect, but for reliability you can choose the series with a higher index. For example, the products of the MURREVA STYL line (Schneider Electric) are equipped with enhanced housings from moisture and dust IP 55, which reliably protect them from spray penetration even under pressure.

The MURREVA STYL case provides reliable protection against mechanical effects and provides trouble-free operation in wet and aggressive conditions.

Where to place
According to the "rules of the electrical installation device", depending on the removal of electrical equipment from water sources and, accordingly, the safety of their placement, the bathroom space is divided into zones. The zero zone is a bowl of the bath, the first zone is located directly above the sanitary pribers, the second is the area surrounding them up to 60 cm, the third begins at a distance of more than 60 cm from all sources of water. All Eui should be placed only in the third zone. The more distance, the safer.
Switches and any other electrical installations are located at a distance of at least 0.6 m from the bath or washbasin bowl.
How to mount
In the bathrooms, all Eui must be equipped with protection against leakage when it leaks. To do this, connect through separation transformers or the differential current device (UDT), also called the protective shutdown devices (UZO). Separating transformers are usually designed for a small power of connected devices - no more than 100-200 W, so the UDO is widely used.
These devices are installed on a DIN rail in the house shield. Their main parameter is the amount of leakage current, which is 10, 30, 100 or 300 mA. The smaller the leakage current, the more sensitive is the RCD, but too high sensitivity can lead to false responses with an increased load (for example, when you turn on several household devices). Therefore, it is most often done: individual lines of the power grid (Lighting the bathroom, a generalized socket group, a socket for a washing machine) are equipped with its own high sensitivity circulation (10 or 30 mA), plus one more powerful RCM (100 or 300 mA) is connected to protect the entire Outdoor network.
In the bathrooms and other wet rooms, the outlets designed for a small load can be connected through separation transformers to protect against current leaks.
Sounds of mounting sockets in baths and saunas
In addition to high humidity, the air in the baths is also characterized by a high temperature, which can exceed 100 ° C (in the Finnish sauna). Therefore, it is necessary to design electrical installation, taking into account the possibility of heating. For gasket, it is necessary to use only a heat-resistant wire, for example, a series of RGCM with an exploitation temperature up to 180 ° C. It is also preferably at a minimum to apply the metallic elements that are very hot. Let's say, instead of corrugated houses, it is better to take a box of heat-resistant plastic for outdoor laying.
Remember: 3 Electric Safety Rules in Bath or Bath
- Choose electrical installation (EUI) with a moisture-proof housing, which will not penetrate moisture.
- Place outlets and switches in accordance with the "rules of electrical installations" (PUE) for the proper distance from water sources.
- The entire power grid in the bathroom should be equipped with a current leakage protection.
