The most common power input cable to the house is done from a nearby pillar. The work, good enough to gain admission to operation of the respective networks. Self-start electric cable home is prohibited. In the old days post conquered by wearing "claws", today used the stairs more often. Weight of strong alloys greatly decreased, and now need to make a fuss is not. Stairs are produced comfortable, foldable. Let's see how an electricity input into the house from the post.
Remove the phase, zero wires from the post
Getting electricity
Switching of electrical wiring and part of the junction box in the column area
Normal post topped with a lightning rod. According to the rules at the base steel hammered count sufficient length (section than 14 square millimeters), the local bus is got. Lightning comes immediately to the ground. Arrester bus electrically combined with the neutral conductor. Nearby hung a switchboard with a counter. Then, an electric cable goes into the trench or air reaches the building. Often happens, there is an empty plot of land. It is a column, hence the need to start work.
Under the plan, at the hands of an electrical project:
- Prescribed quota of energy consumption. Guaranteed by the State, gleaning limit in the future will have problems. Properly compiled electric project acts as a guarantee, after the cable entry into the house will not have to change anything.
- Part of the modern household is supplied with three phases. Clearly, the likelihood of complete failure of electric energy is reduced. Later on the territory of the house put the relay track the presence and phase shift, whereby the principle is put into practice.
For the construction of electric power is required, the box below the main supply a low temporal fitted socket. Builders provide energy. After the completion of the temporary terminal box is removed from the socket. Most units are needed to seal. Please inspectors local grid, list options:
distribution Box
- Under the rules of the equipment is supplied with a certain level of more powerful means of public power is turned off. The neighbor can leave without light, if something goes emergency, emergency, firefighters will be able to secure (and victims) against electric shock. At the entrance to the cable junction box is placed a three-phase electrical switch.
- Counters of various types. Above said phases one and three. In the latter case, the cost of equipment increased sharply, more complicated composition. For improving the reliability have to pay. Counter type is selected according to the requirements of local grids (power, active and reactive).
- After the counter put pole, two-pole machines protection. Terminated when overloaded network. You should know, the counter can be bought with a protective function. Some models allow to set "important" and "minor" branches. When overload is primarily cut down the last. Type of circuit breaker is determined by the electrical design of the house. Bipolar expensive.
breakers seldom sealed. Contactor (switch) shall be subject to the procedure: preventing local bouncer put other, cheap, do not meet safety requirements. Of course, the sealed counter. You can buy multirate, sealed connectors, and device programming (setting at the right price on the days, hours). USB ports, aging COM.
How to conduct the electrical connection of wires and cables
The junction box is zero local bus. It is got the local ground, in common with the lightning rod (one of the reasons for the prohibition of the use of video recorders in a thunderstorm). The branch joint is performed, such as "nut". Earthing lightning conductor represented bare steel reinforcements going down below the soil surface. The oxidized steel trimmed with a file (sandpaper) on the contact sleeve length. Starts side copper wire provided with insulation yellow-green.
Be sure to ground the shield to be the case. You can use a threaded connection, using the rivet to attach a special needle. For the construction of communications used by living with a yellow-green insulation. Often special terminals on the body is not present, then the mounting holes are drilled on site. It is important at this point to clean the paint from the inside, ensuring a reliable electrical contact.
Wiring in the house
The cable extends inwardly through a special input. Normal composition: two or four wires, one wire is zero. breakers are put into phases. Sometimes electric project requires a tear also neutral. Machines used for double-pole single phase. Under the rules of the isolation of the neutral conductor is blue or the same color strip, winding around the circle. Even if from the column are other wires, use this variant for the local wiring.
According to the current rules in the home ground is present. Pull the electric cable from the post would be a wrong decision. Circuit lightning building is formed by at least two pins (each of length 2.5 meters below ground level with a distance of about 3 meters). The owner is empowered to make their own branch. Described the process of making proper lightning rod, how to build the circuit. Here you need to:
- First, start with the neutral conductor pole.
- Secondly, to bring grounding electric network of the house.
- Simultaneously, an electrical cable or a simple wire rod 6 square millimeters performed protective equipotential.
To summarize: the cable is made with two or four cores. Section is selected according to the power. Take stock. For example, 25 amperes 6 square millimeter of copper. Posting is selected, allowing the machine is guaranteed to work before the onset of congestion. Suppose the nominal current of 25 A, in excess of 13% network will operate over an hour, 45% - somewhat less. The cable must withstand 35 A three-phase network with insulated neutral scheme - Inventories more.
three-core cable
A three-wire cable of this section can withstand 35 A (per core). Installing automatic 25 A, ensure the system is operating. The main question - to connect to the post! Zero lower wire available. One level took two cores - need to be right, as seen from the substation. Color-coded is indicated by the blue line, branch off to the neighboring poles contours of lightning rods.
power input cable is attached to the house with the help of branch joints (of the appropriate type). Suppose the bare wire to plant on a regular nut. The main phase conductor for installation do not touch the other branch. Guaranteed death. Much safer piercing couplings. Side branch, choose to make electricity input in a wooden house, mounted on the ground. Electricians rises to the top, core touches as intended.
Forums bombarded with questions: How is the electricity input into a private house. Given the advice: do not interfere with professionals deliberately do wrong. Electricians are aware of where to lead, the only thing you want to use the clutch to avoid twists.
Electricity is put into the building
In practice, the cable entry hole drilled required diameter with a margin. Inserted inside the insulating tube. Pushes the electrical cable. Clearly, it is inconvenient each time obegat pole disabling phase cellar provided with additional switchboard. However, the place of deployment defined communications structure. Assume electricity input into a private house is realized by air at short distances, the basement will not place the best one switchboard.
It should be guided by common sense. Putting electricity into the house under the ground certainly more expensive. The cable is equipped with armor, making it difficult to strip, docking, mounting. Products considerable weight. When choosing a design, use an online calculator like the specified link: http://allcalc.ru/node/507. Of course, for electric cables cross-checked information. In successful cases, the means of calculating the human language options offer a lining of communications. For example, "electric cable in the air according to GOST 16442".
Greatly facilitated the process of completing the purchase. The standard provides a description of brands of cables, gives instructions to the underground laying, through the air. It becomes clear that you can do, can not do. Then we calculate the price. Part of the installation is docked cable connection to terminal devices. Used coupling, sleeves, caps. Rules of electricity entering the house will require a quality of contact. Copper sleeve on the end of wear at least two ways:
- By means of hydraulic, otherwise press the tip of the electrical cable is crimped in place. In some videos recommended pliers, strongly disagree. Hand pliers pull out a thousand five (end 2015), hydraulic and electromechanical expensive. Crimp can be conducted square, star, hexagon (the latter is more expensive).
- Due to the high cost of ticks handicraft masters practiced soldering. Before making electrical input in a wooden house, purchased burner on collet balloon little gas. Strengthened copper tip vise sleeve upward. Structure luditsya for removing the oxide film. Inside imposed a fair amount of solder is heated, top cable lived vdevaetsya. The wire is pressed, melted insulation until it stops. We wait retaining position, cooling (useful to blow the air heating point).
It is not often wrestle with how to make electricity input into the house, it is recommended to buy a torch cutter. Issue price of 2000 rubles, the thing is certainly useful for other purposes. Build aluminum wires. To make sure the correct input of electricity into the house, requires a pair of elements. Clutches briefly considered earlier. Let us consider the inputs. Special mounting elements, protects the cable against kinking in the input field in the junction boxes and other components. Internal devices are protected against dust, moisture.
Replacing electricity entering a private home may cost a round sum. Rare miser wants to spend, buying stuff. The price of the cable glands is relatively small. Meet the requirements for the electricity entering the house will be easy.
