Wiring Accessories - it switches, sockets

Any modern construction regardless of the purpose of the object under construction is impossible without the implementation of a number of electrical work. Lighting facilities at the initial stage of construction and subsequent commissioning are inextricably linked with the reliable, high quality and relevant safety standards compliance of electrical work at different levels of complexity. The quality of any electrical work is defined by two, inextricably linked components - it is the responsibility and professionalism of the electricians, and quality used in the materials and equipment. But even a professional electrician can guarantee quality and safety made it work without the high-quality materials and above all wiring accessories. About them, but rather on those with whom we most often encounter in everyday life, and are described in this article. Let's start with electrical outlets. Why should I socket? To make it something to include. And what: television, iron, lawnmower or a pump to irrigate the beds at the cottage? Hence the requirements for most of its socket and the device. In everyday life usually use the socket contacts, designed for currents of 10-16 A. The latter tend to have more and ground contact, and allow you to include these powerful consumers like microwave ovens, washing machines, clothes dryers, vacuum cleaners, detergents, etc. Street outlet have a higher degree of moisture protection and improved mechanical strength, are often provided with covers for safety and protection from water droplets. With some assumptions here include the most simple extension of length 3.2 m with plug on one end and a socket (socket) on the other, as well as complex systems with Interference and protection (often electronic) of emissions and surges in the mains. There are extensions to the current device (RCD), which almost instantly load shedding in case of a slightest leakage currents. By the way, and these devices themselves - the same wiring products. Specialty sockets and connectors for connection to telephone and computer networks, high-frequency connectors for connection to cable television networks are also included in the product range and can be a variety of colors. There is a very large number of varieties and designs of devices in the series, which opens up opportunities for interior design. When purchasing a note to the nominal load current, workmanship, availability of ground contact. To connect the power consumers such as electric stoves, pumps, often using specialized outlets, sometimes three-phase. The design of such outlets is that the ground pin is always connected first and disconnected last, providing a complete security system. Electrical outlets are available today, most diverse: from simple to very complex models with elegant design and special features such as high degree of moisture protection and high operating currents. Below is a brief description of some of them: -, shuttered - recommended for installation in apartments where there are small children. Openings of such outlets are protected by special protective shutters that open only when the simultaneous introduction of a pair of metal pins plug into the socket. Insert into a socket or a finger nail child can not - with ejector fork. In the corner of a wall outlet is a button, when clicked, triggers "slingshot", and the fork is pushed out of the socket without any effort on the part. Remove the plug from the outlet with a "catapult" you can not even touching it. This design greatly increases the life of the product - from the ground - is designed for 3-pin harness. When plugging in the first contact with each other is grounding contacts, and only then those that conduct a current. Almost all imports outlets have a third grounding prong. To date, electrical safety standards for installation in flats are recommended grounding outlet - for installation on the street. Typically used for connecting gardening tools, such as lawn mowers. These sockets are fixed, usually on the outer side of the house, garage or ancillary building. Outlet for outdoor installation should work, despite changes in temperature, rain or snow. Therefore, you should choose the outlet with a high degree of protection and protective cover - for rooms with high humidity. To install the outlet in the bathroom, shower or bathroom fit the socket marked IP 44. Within such outlets are more rubber gaskets. True, the usual socket with protection from moisture suitable for use are not very powerful electrical appliances (eg electric razors, hairdryers). For a more powerful electrical appliances (eg washing machines) will require an additional installation of UST. In addition to power outlets (with shuttered, with ejector, grounded, with a lid, etc.) exist and low-power outlet. These include: antenna, satellite, telephone, computer and audiorozetki. Manufacturers are also very much: Russia, Belarus, Turkey, Germany and others are presented in our market, and such renowned companies as ABB, JUNG, Lexel, MAKEL etc. And another important point. If you use any kind of adapter to plug in one standard to another, keep in mind that this is not wiring products. Abroad, you pay a large fine for using such a device, and in our "Rules for the Construction and operation of electrical equipment" they are also not given. Such devices are extremely hot, which is the result of bad contact. Then the process is like an avalanche: an increased release of heat is further exacerbated by contact. Heat is becoming more and more, especially noticeable when the adapter is enabled through a powerful consumer of electricity: a vacuum cleaner, hair dryer or iron. Do not be stingy, change the socket or plug, if they do not match each other. Further, a closer look at modern switches. We have become accustomed to the push button, when clicking on one of his half-light switch on and press the opposite - turn it off. Or light a light touch of a button. Another pressing - and he goes out. The general principle of operation of all switches is the same: to create a reliable contact, or as reliably break it. As when you turn on and turn-off switch skips the spark that really is not conducive to prolonged use of this device. That is why contacts are choosing the materials that this spark is not destroyed: silver, metal and special alloys capable of long work in harsh conditions. The more powerful the load, ie, the more light bulbs connected to the switch, the more sparkle. Therefore, when choosing the switch should be considered a guaranteed number of inclusions and the maximum power which he can commute. With the first option is more or less simple: the modern switches allow hundreds of thousands of positives, but the second option is to pay attention. If low-power switch turns the spotlight illuminating the building site, it quickly breaks down. When exceeding the maximum power, which is designed switch working contact surfaces are covered with craters by erosion, there is a layer of oxide and soot, which seriously affects the conditions of the conduction current in the contact area. Next - high heat, oxidation, contacts and all - replacing the switch. There are also switches for the control mechanisms curtains on the windows, electronic dimmer - Dimmers, allowing continuously changing light in the room, they also refer to the wiring accessories. Modern switches with backlit keys, or even with a full backlit decorative frame can serve as "beacons", indicating the way in the dark. These devices are made as Russian manufacturers and our neighbors from the CIS countries, as well as eminent western firms. When you purchase should pay attention to build quality products, the reliability of all the contacts inside, then how he will connect the wires. In Russia installers prefer to use as clips for wire screw terminals, overseas assemblers move to quick-connect. In any case, all electrical connections must be extremely reliable, and does not alter the electrical characteristics over time. Very often, in order to save the houses set aluminum wiring. Aluminium - soft and flowing metal, so with time fitting using aluminum "flows", and electrical contact is deteriorating. Hence, the increased heat in the contact area and more rapid deterioration of the contact, up to complete failure. So use the switches in purpose and do not use them where this can not be done. If you permanently leave your home, it might be worthwhile to install a programmable switch, which stores the time of the on / off light and simulates the presence of people in the house when you do not. By type of installation sockets and switches produce: for outdoor installation - they are assembled in laying open electrical wiring, sockets and switches for hidden installation. In the installation of switches for hidden installation of an additional piece is a steel or plastic box: first to build in the wall of the box, to which the spacer tabs and screws secure the outlet or switch. It is these sockets and switches are usually installed in flats. Many firms, including those listed above (for sockets) release Wiring entire series, when one design is sustained and sockets and switches. The outer part of sockets and switches can be not only plastic but also metal, wood, as well as combined. You can pick up products, combined with wooden furniture, or buy sockets and switches, the appropriate style of the interior. Thus, for the interiors of hi-tech products are ideal unusual shapes, such as the switch in a rectangular enclosure with a key in a circle. In any case, competent and professional assistance in choosing the equipment you will have the specialists of the company, where you will acquire.
