Installing a light switch in the bath

For an experienced electrician with experience not pose any difficulty setting and the subsequent connection of the light switch. In fact, the difficulties with the resolution of this problem should not occur and the common man, not having special education, but who knows the intricacies of the work. However, this will need to comply with rules set by the Code of electricians - SEP, as well as consideration for working with electricity, because the work is associated with risk. light switch is needed everywhere, and the subtleties of its installation will need to install it in the bath or in another room.

Qualitative selection of "captain" of electrical wiring

The rank of general reserve to himself as the switch will be made with our hands. Col. Rank is assigned the old sample packet switch, or a new two pole circuit breaker, which is installed in the shield of the electric supply. The Colonel will give the order to the captain at the time of connection to the network for complete stress relief.

Important! While working with the electrical wiring of the object, which made any electrical work, dozhzhen be necessarily de-energized. Another important point is that for working with electricity confidence has no place, that is, do not trust inexperienced teammate important tasks.

Switches are selected according to the type of electrical wiring, which may be of the following types:

• open, providing wiring pad and cables on the wall outside;
• latent (hidden), which provides the execution of electrical wiring inside the wall by special channels, referred to as the cutting grooves.

In the case of an open type case wiring situation is simple enough, but in the case of wiring gated in the bath, where there is a high level of humidity, work is somewhat more complicated and requires more knowledge of employee. Thus, the required electric circuit network, by use of which will be further defined possible installation point switch.

Switches for both types of wiring structurally different. Devices hidden type, serving for switching on and off, up against the wall, with pleasing aesthetic holders only protective cover. Filling device so to speak "recessed" in preformed recess. The mechanism stopping the supply voltage, i.e. normally closed current path is located in a special dielectric Escutcheon, which is similar to a shallow plastic cup shape and size.

Strictly speaking, this is set to podrozetnik shaped groove. Next is the fixation Enclosures hidden in drywall partitions through specialized struts in concrete and brick walls. Installation is carried out without the involvement of plaster mixed with water and adjusted to a consistency similar to sour cream. Switches for the electrical network instead of the open sample cup-shaped mounting devices are equipped with a flat metal or plastic platform. It is attached with screws to the wall, made of wood, and to brick or concrete through the use of dowel-nails. Both types of switches have an equivalent amount of structural components: Escutcheon, decorative and protective components, the command mechanism.

Procedure for installation: concept

Mounting of both types of devices is made by analogy. Thus, during the switch assembly are general principles of operation, and even a single procedure algorithm.

Work algorithm:

• from the start switch assembly is fixed Escutcheon which is a pad or cup;
• after that you are connecting devices to turn on / off light. The work done by creating a true conductive connections between the conductors and the command authority;
• then the mechanism is mounted on a plate or in podrozetnik by spacers or screws;
• at the end of the above steps work results covered with a lid, and put on the keys.

The main snag is wired properly to the operating control switch body. In order to clarify the task and connect the wires correctly, you need to know the wiring diagram and some knowledge of the physics of electricity.

Wiring plan Switch

Failure to comply with the rules of assembly considered adaptations promises overheating and electrical circuit with sincerity. Another unpleasant aftereffect wrong connection is to keep the voltage in an electrical wiring, because of what would be an impossible task replacing a blown element even after shutdown lamp. Should remember about the mysterious "fields the" and phases. "

What you should know:

• neutral wire should be displayed on the lighting device;
• phase is conducted to the switch, which, strictly speaking, blurred. In phase area should be closed circuit to the bulb when it is necessary to light up and died out. If the switch apply zero, while a Lighting - phase, for the safe replacement of light bulbs have to be sent each time a distribution box;
• from lighting unit to turn off the device as being the phase portion. Switched on and off from the circuit of clicks on the keys will be in phase discontinuity channel, i.e. location, wherein originates phase interval allotted to the bulb, and ends the wire that comes from switch.

In short, to the lighting device (lamp) will have two hundred at once, and phase and neutral wires, while the switch - only phase. Note that all data must be cunning weave in a special insulating box. In principle, should worry about such niceties of home craftsmen who specialize in the installation of the switch in the room.

Connection conductive sections are made at junction. box. The channels made of plastic ducts or wiring in the wall is extremely undesirable because Complications will arise with damage to the wiring areas during repairs, which sooner or later need. If a junction box near the switch with no installation place, it becomes possible to broaching the phase and neutral wires from the opening panel.

one-button switch assembly principles described above apply to the arrangements for the inclusion of two or more light points inclusive. Accordingly the number of keys can be in two such switches and more. Each key is supplied section of phase wire from the lamp, the operation of which the key controls. It is worth paying attention to the fact that the live wire of the junction box is carried to the switch with a different number of keys only one.

About the color channels and labeling of live

In most cases, the improvement of the electrical equipment of the bath, at home, or apartment is trusted electrician, that is qualified. The most common reason for using the wizard effort is considered a replacement device when the point of installation are supplied zero and phase conductor channels.

Important! The new plant is switched off the device or replacing it is produced exclusively in the presence of the entire range of drives that form an electrical circuit. By this recommendation, we recommend to treat with all the trepidation inherent in you.

To newcomers to the electrician had no problems with the definition of the zero and phase conductor was invented color differentiation with respect to which is to talk without fail.

Separation by color:

• phase wire has a white, red, or brown color;
• neutral wire has a blue color;
• ground wire indicated by a green, yellow or green-yellow stripes.

Additional services from the manufacturer - a designation of points connected with the letter L with the number. For example, say that a letter with numeral L3 denotes a phase at the input switch dvuhklavishnom. The opposite side of the device to turn on and turn off the light may include designation as L1 and L2.

Which is easier: to stick or pinching?

For reliability and ease of formation of connections, connection points of disconnecting devices are equipped with screw-type devices and those who are stuck. Contacts and sticks firmly compressed bare wire spring one centimeter. To disassemble the connection with the other moans of this type of device has a button.

Screw-type contact must be tightened with a screwdriver, a pre-positioning terminal about two centimeters bared wires. It is worth noting that under the terminal should not be a one millimeter wire insulation, otherwise the insulation oplavitsya, and will pose a threat to the landlord.

Installation Surface switch

Suppose that we have a switch for open wiring. This switch in the factory and the key one. Setting this switch is performed several steps in respect of which it will be carried on.

installation algorithm:

• taken slotted screwdriver and its key podkovyrivaetsya carefully;
• then remove the protective and decorative cover and operating mechanism is disengaged;
• switch disassembled, thus must remain in the hands only Escutcheon plate. On this plate has holes for fixation;
• plate is applied to the mounting portion. Marked point and the line of the upper edge;
• Escutcheon screwed-platform horizontally by galvanized screws;
• the wires are cut accurately;
• the mechanism is connected to the wiring, and the following tips labeling;
• checked quality of the electrical connections through the meter;
• mechanism is screwed and put the lid.

As a result, minor time costs you will be able to make a qualitative and reliable to connect the switch in the bath. When working with electricity must be remembered that the electrical home network is sufficiently dangerous for the person who does not know the physical laws that apply in the electrical business.
