The power system of any house or apartment includesThere is a large set of auxiliary equipment to ensure the uninterrupted and safe supply of electricity for the whole residential area. A very important part of the power system is the junction boxes, which reliably protect against electric shock when cables and wires are disconnected indoors.
Classification of piercing boxes
With the help of distribution boxes,wiring to a variety of wiring devices and devices. Installation and operation of electrical installations are carried out in accordance with certain rules, in which it is clearly stipulated which particular junction boxes should be used in certain areas. Today, there is an extensive line of wiring products designed for use in a variety of installation projects.
These products are made from differentmaterials, different types of wire fastening and protection class (IP). All of them are divided into two groups - for hidden and open wiring. Accordingly, when you install the switchboxes, different technologies and tools are used. So, the inner box, intended for concealed wiring, is built into the wall plane into the prepared technological niches. And the external box is mounted on the wall by means of traditional fasteners.
Rules for the installation of distributor boxes
Premises with high humidity,It is necessary to equip with sealed junction boxes, in which the protection class is at the level of IP23. In wooden houses it is recommended to put boxes of metal for soldering. The main task during the installation of this equipment is to ensure a reliable contact between the wiring wires.
At present, the method of soldering and insulating tape is no longerrelevant, tk. Convenient and high-tech clamps are now available for connecting cables, ensuring safe and continuous operation of industrial and household electrical wiring. When installing the boxes, you should remember that you will need to do their regular revision, so you should install them so that access to them is free, and it was possible to visually inspect the inside of the box without dismantling.
Raspail boxes: advantages and disadvantages
Advantages of using junction boxesobvious: firstly, the amount of wire is significantly saved, because to connect a few outlets, it is enough to hold just one line to the box, and from it, already divide the wiring into the sockets. Simplify the combing boxes and preparation for laying the wiring for the absence of the need for multi-meter shtrob. However, there are some drawbacks in them. One of them is a decrease in the reliability of the wiring diagram. The fact is that the wires can oxidize over time, and because of this, heat up, which causes damage to the wiring.
