many things you can do with your hands, but not all seemingly simple thing can be done in any handyman.Installation switch as sockets, may be performed according to European standards, or at least following reason.But in any case, it must be safely and reliably.
comparison can recall the appointment of master switch in the car: security and economy - these are the basic criteria of quality, and "smart" devices that surround us every day.

installation sockets in the room: what we build a house
point type electric sockets installed in locations where access is required to the electrical power network.This means that the installation of one or several points in the particular room layout begins wit
If a few decades ago, installing sockets require the use of almost a jackhammer, the current building and finishing materials prirovnyat this procedure, for example, with the installation of a plinth.Indeed, today laying electrical wiring and simultaneously with the installation of elektrotochek become routine procedures do not require much effort.
But despite the simplicity of the installation requirements for electrical safety rules remain the same.
For example, the height of the installation switch or outlet - is absolutely no difference in this case - should be sufficient to ensure that the socket could not be flooded if the pipe will burst or toddler crawling on all fours, I could not get it to yourself.
All these factors are taken into account when setting the socket, which is necessary to make the wiring layout and places the installation of sockets and switches.
General Rules of installation outlets are: the distance to the window sill must be at least 10 cm to the floor - not less than 30 cm, to the doorway - not less than 90 cm.
However, in some areas the rules of installation sockets can deviate from the standard;for example, the height of the installation of switches and sockets in the kitchen can be equal - at least on the surface of the table or kitchen furniture. Aesthetic side demands that the height of all visible elektrotochek was the same, at least within the same premises. course, for open installation is easier to implement, but it ultimately depends on the willingness.
Currently, flush-mounted socket used round plastic boxes under which drilled holes.Even if you have to deal with the concrete wall, the crown on the concrete drilled hole and then a chisel or a chisel hollowed remains of the wall.
alternative is drilling holes in the perimeter of the planned, after which the pieces of wall knocked out by hand.
When the power tool is not at all, the chisel and the hammer will become an indispensable tool in site preparation for the installation of a wall outlet box. to "drown" the box in the wall, you need to make the hole a centimeter and a half deeper than the box - then the plaster around the box will be able to hide all on the level of the wall.
boxes (Escutcheon) mounted inside the hole with the help of plaster - it is quite uneven, as well as on the concrete wall, so that it can be fixed with an aqueous solution of gypsum or plaster.
itself is mounted in a socket podrozetnik either with screws or by sliding feet, the latter option is currently preferred because it takes less time.After this remains a very close outlet plastic housing.
If repair or finishing work in the room is not finished yet, the outlet hole is plugged with paper, and the very same outlet with something close for a while.
installation switches different designs: the same features
in general and detail setting switches is similar to installing a single outlet, as discussed above.However, there is also a number of differences, especially when the will, for example, the installation of series switch, but more on that later.
As already mentioned, the installation of switches is identical to installing sockets, difference lies only in the ease of use - the switch, as a rule, must be within arm's length person standing .However, access to the switch should not blocking anything.In addition, the installation of the switch dvuhklavishnogo, three- or more requires such its location at which the wiring electrical wire would not cause any difficulties.
Another very widespread disaster is arbitrary circuit breaker installation.Terms of overt and covert installation of switches required to switch breaks the circuit of the phase conductor.
Indeed, any professional installation manual switch shows that blackout "phase" removes tension from a certain section of the circuit and provides the ability to produce, for example, minor repairs wiring or replacement of incandescent lamps without shutting down the entire room from the mains .
In real life, random selection or zero interruption phase wire - 50 to 50 of all cases - making the switch for outdoor installation, however, like any other construction hazards.
For example, in multi-storey buildings occur leakage of water from the top floor to the bottom.In such cases, wiring channels are the most vulnerable point and the probability of hitting the water in them is very high.By ak consequence, there is circuit in wiring (even when it is in the "off"), and full or partial withdrawal of its failure.
However, the most dangerous is the fact that the installation of the switch from non-compliance with this rule may result in electric shock someone from tenants who may be, for example, in the bathroom and not be aware of the danger.
Installation flow switch: a reasonable complexity
Installation flow switch is remarkable not only because of the above-mentioned potential problems, but also because of the connection circuit breaker is more difficult than usual.
Wiring flow switch indicates that the neutral conductor not interrupted by switches, but the phase conductor must always be interrupted.
When installing the switch dvuhklavishnogo or trёhklavishnogo, the attention to the observance of this rule should be even more - important not only to the safety of the inhabitants, but also the correct load for a particular section of the circuit.
example, switch trёhklavishny open installation makes each key independent;that is, each key - it's like one-button switch is open installation.
In trёhklavishnom embodiment middle switch differs from its neighbors - it is suitable, among other things, a greater number of wires (in the extreme switch has three wires, and the central - four).
On the one hand, it imposes additional requirements on the wire channels (they need to be able to put more conventional wires), and on the other - at the design stage of installation of wiring fact breakers must be justified.
Installation breaker: effective reliability
installation of these devices is a separate topic, given the responsibility of these machines. First, you need to understand the principle of operation of the circuit breaker and the role of the factors affecting its performance.
To properly calculate the nominal parameters of the circuit breaker of the future must take into account the views of the wire (in most cases is either aluminum or copper), its cross section (the larger section of the wire, the more current, and hence the load wire can withstand without overheating) and the type of wiring (concealed or open, for outdoor installation characterized by a more intensive heat dissipation).
for domestic purposes, that is, where is mainly used two phases and the rated voltage is 220 V, single- and double-pole, used machines.The main difference between them is the ability to simultaneously switch off not only the "phase", and "zero", which is more correct.
Rated current, which can be calculated by the device can be from 2 to 63 A.
In conclusion, it must be added that the use of circuit breakers is much more effective than the use fuses of the last century.
The cost of installing the switch: where is the limit of thrift
there are "trendsetters" in the market of electrical equipment - VIKO, SCHNEIDER, LEGRAND, MAKEL - have long provided a lot of little things that are important when installing the various switches.But even these achievements can not shorten set of small but necessary operations, a summary of which, together with their value for Moscow and Kiev (ruble and the hryvnia, respectively) is provided here:
- installation podrezetochnoy box - 250/45
- setting single- and two-pole machine - 250/40
- installation of the switch - 250/20
- installation of flow switch - 350/25
Of course, the price lists of service providers in the market and installation workmay contain several tens of positions and for a better understanding of what you need to pay money to better preview demonstration of the "installation of switches" (video reports of specific companies will give a full picture of the level of their services), "the assembly machine" and so forth.
