In the USSR, it was considered that it was much more convenient to wash clothes.in the pelvis, and shaving will be as efficient and clean as possible if you use the Neva machine. Hair dryer, to dry hair, was considered a bourgeois excesses. In our modern and technological time, builders, engineers and designers still adhere to this point of view. So much more convenient. But when the average person makes repairs in an old apartment or moves to a new one, the socket in the bathroom must be present. Attention is often paid to this, and often the matter is not limited to a single outlet.
In the modern bathroom, which is equipped withthe latest canons, in addition to the washing machine, there are other electrical appliances. Now you can not survive without a boiler, bath with hydromassage or mirrors with light. But the bathroom has special conditions. There reigns high humidity. Therefore, the installation of outlets in the bathroom requires a serious approach. After all, humidity and electricity are a serious danger to life.
Specifically for the bathrooms of these elements are not, andthose that are still on sale, do not differ in a special variety. They are classified only by two signs. This is the power that a particular device is capable of withstanding, and the number of consumers that connect. As for the number of devices, everything is very clear and understandable. But in matters of power electrical devices should understand. Measure current in amperes. For especially powerful equipment (and it can be boilers or washing machines), sockets with 16 or more Amps are needed. A less powerful outlet in the bathroom with a washing machine or other appliance will simply melt. This is a significant risk of closures.
В ванной всегда влажная среда, и замыкание может lead to very unpredictable consequences. For low-power appliances, such as hair dryers, razors, curling iron, there are enough items of 6-8 amps. Before buying, it is important to find out what are the differences between conventional solutions and those for bathrooms. Often for these types of premises is recommended to use waterproof sockets. They are equipped with a cover that is able to protect the appliance from splashing water. Also, experts recommend to purchase and install sockets with a third contact, designed for grounding.
Some people are still confident that mountingsockets in the bathroom is strictly prohibited. Yes, such a ban really was, but after 1996 it ceased to exist. But there were good reasons for this ban. The bathroom is a rather complicated environment with the presence of a bath, water intake devices, a huge number of metal pipes. Of course, it can be said that steel pipes are the last century, and the bath is more often plastic. But the number of home appliances has grown.
The ban is no longer valid.Removing it is due to the large distribution of various means and systems of electrical safety. Do not install outlets in rooms such as saunas, baths or showers. The socket in the bathroom of a private house or apartment is quite acceptable. Also allowed the installation of elements in the bathroom of hotel rooms. But in the rules there are certain reservations.
Connect the socket in a wet roomallowed only if there is a safety shutdown device on the network. In this case, the tripping current must be no more than 30 mA. As an alternative to such devices, isolation transformers can be used. The maximum level of protection can be provided by mounting two devices together. This is done voluntarily, and in the rules it is not. If water enters the outlet, with high resistance, the device automatically shuts off the power supply.
The electrics in the bathroom should be grounded. And the socket itself is equipped with a third contact. However, it is not in every house. UZO, and also transformers can work and without it.
But as for the level of protection, it will be much lower than it could be. It is recommended to ground all metal systems and devices to the maximum. This will reduce the risk of short circuits and fires.
Wiring must be hidden.Allowed to use and outdoor installation. But in this case, all the places where the wires will be connected, are carefully insulated. Installation in metal pipes or steel metal hose is not recommended. The socket in the bathroom should be located at a distance of not less than 60 cm from grounded plumbing fixtures. Also, it is not allowed to install the element closer than 60 cm from the doors of the shower cabin. The minimum allowable height at which installation is possible is 130 cm from the floor level.
In clause 7.1.47 PUE indicated that the bathroom or shower room is divided into four zones. Each of them has specific requirements regarding electrical safety. Zone 0 is a place inside a bath, sink or shower. It is allowed to install water-protected electrical appliances with voltage up to 12 V type IPX7. At the same time, power supplies are installed outside this zone. Installation of the outlet in this case is prohibited.
Zone 1 is a place under the bathroom, above the sinks,showers, bidets. It is allowed to install water-protected water-heating devices, as well as lamps with a protection class of at least IPX5. In this case, the "protective zero" is necessarily connected. Sockets in these places are prohibited. The heater can be connected to electricity through a fully hermetic inlet or to an outlet that is in the third zone. Zone 2 is all that is at a distance of 60 cm and further from the first zone. It is allowed to install lighting devices with IPX4 class moisture protection. The installation of fans is also not prohibited. But the installation of outlets is prohibited. Zone 3 is all that is at a distance of 2.4 m from the second zone. You can install waterproof IPX4 sockets here. But they are connected through safety devices with a grounding contact. Outside of high-risk zones, the installation of conventional IPX1 class sockets, installation of junction boxes and control devices is permitted. But you need to connect through protective equipment.
Any electrical appliances (sockets including)marked with a special marking - IPXY, where X - is the level of protection against dust, and Y - against moisture. For the bathroom it is recommended to use sockets and electrical appliances with a class of protection against moisture not lower than the fourth. Electrical appliances marked “0” are not protected from moisture. Class "1" provides protection against condensate. The second and third - from the effects of vertical sprays.
Она может осуществляться двумя способами.This is the installation of a new point in the old place with the replacement of electrical wiring or the installation of a point with a new wiring. The installation process takes place in several stages. For outlets should be allocated a separate group with cable. Before proceeding to installation work, the line must be equipped with a separate machine. What it is? This is a special device that automatically turns off the power supply to the consumer. It is installed if there is a boiler or washing machine in the room.
If powerful household appliances are missing, you cando without it. Often its capacity is 16 Amperes. When installing it is necessary to sustain a height not lower than 60 centimeters from the floor. Required ground wire. The ideal choice is a socket with a lid. If the installation of elements without repair is carried out, then it is equipped with a separate cable that connects to the shield through the machine.
The first step is to find the right one.outlet and decide where it will be located. In order for the installation process to pass quickly and at a high level, the necessary tools should be prepared. So, we need a socket protected from moisture (6A or more). You will also need a screwdriver with a cross profile, a special tool for dismantling the insulation, an electric indicator, and a hammer drill.
If a new electrical point is established,but the repair is not done, then choose any devices. If repairs are being made, and the wiring changes as well, then for more aesthetics, you should choose embedded products. Outlet outdoor installation is very simple. So, in the first step, drill holes for fixing dowels. Then prepare the wires. This is cleaning the insulation of the cable ends. It is not recommended to use a knife, otherwise you can damage the wire. At the next stage dowels are installed. The wires are connected to the socket, and the case is fixed on the wall. The outdoor outlet protected from moisture has special openings with plugs.
Without a doubt, the outlet in the bathroom is needed.What sockets to put in the bathroom? Definitely those that are protected from high levels of humidity. This reduces the risk of short-circuiting and flashing.
