Wiring Devices: plugs, sockets, electrical switches | Company Build-Invest
Probably many of us have heard the phrase "wiring devices." But what lies behind this boring technical term, know, most likely, not all, but most use these devices pg daily. It turns out that the so-called qualified electricians sockets, switches, sockets, plugs, junction boxes, fuses, in short, all the usual items, without which our lives would be plunged into total darkness. And in the truest sense of the word.
Of the variety of wiring devices in everyday life we often come across switches, electrical outlets and plugs. Their destination: switching pg circuits and fast connection to various devices. pg
Design features a variety of wiring devices: the product of classical forms that are not subject to short-term fashion trends, models, giving pg the interior a personality trait or having a well-defined functional design. The color palette of these devices can satisfy the most demanding tastes - and strict white or black, and all colors pg of the rainbow (which are only some names of colors - "blue sapphire", or perhaps "green safari").
In addition, the products produced, painted by precious woods ("red maple", "dark oak"), and even those with shells made of this wood itself (GIRA). Therefore, to achieve a combination of them not only with the wallpaper, but the wood-paneled wall paneling or furniture - a task doable. But this is not the limit. Some companies produce switches and sockets with decorative interchangeable parts. Enough to replace the thin ring of the same but different color to change the look of podnadoevshy switch.
However, admiring the stylish design of modern wiring accessories, do not forget that these devices operate in networks with hazardous voltages. So the first requirement for them - complete safety in operation, which is achieved to a large extent, design measures: in serviceable and correctly installed switch or outlet all bare live parts inaccessible to the touch.
The maximum allowable voltage and current, which is designed to a specific type of device is indicated on the package. Exceeding their lead to overheating of the switch (socket), which can cause a fire. Avoid such an undesirable course of events is very simple - just pick up the switch corresponding to the current in the circuit and its voltage.
Versions of wiring devices are mainly determined by the conditions of their use (raw or dry conditions), overlooking the wiring (open or concealed), purpose (of switched circuits) and the need for protective ground (neutral). The usefulness of the latter (ie, grounding) no doubt who already does not. Therefore, the construction of modern buildings wiring performed with a mandatory safety ground circuit and use the appropriate switches and sockets. In older homes also have to make do without safety devices contact (they are just not connected pg to anything), and modern appliances with euro (microwave ovens, kettles, irons) connected via adapter plugs.
The degree of protection from external influences, ie operating conditions, wiring devices in accordance with the standards of European countries pg classified IP-code. The structure of the code consists of a pointer (the letters IP), and follow it two digits. The first (from 0 to 6) indicates the degree of protection against penetration device foreign objects and dirt, second (0 to 8) - for resistance to moisture. The vast majority of switches and sockets for rooms with normal climate conditions have a degree of protection IP20. Devices in the splash-proof design to be installed in areas with high humidity, such as bathrooms should be performed according to the norms IP44.
By their construction rotary switches, rocker, pushbutton, in appearance - for open and concealed wiring. A variety of loose-leaf pg designs are widely used key switches. pg Depending pg on the number of switched circuit breakers are one-or two-gang, but can sometimes be found products with four or even five keys. For the convenience of finding the switch in a dark room, many models pg have a backlight on a miniature gas discharge (neon) lamp.
The maximum current, which is calculated most types of rocker switches do not exceed 10A. Some firms use in their products contacts of alloys with a high silver content, which allows switching circuit
