The underground method of introducing electric power into the building is always more expensive from the air analogue. This is due to the moment that the installation work is more complex and laborious processes, and the material itself is also more significantly. However, of course, there are also their positive points. Of course – the appearance of the adjacent territory, which does not deteriorate with hanging wires and supports. This method of entering the cable into the building has its own, special rules for installation work.
The cable is laid down the pillar, to the trench. It should be protected from the effects of a mechanical steel pipe to a depth of about two and a half meters.
Laying rules
The depth of laying the material should be in the range from seventy centimeters to a meter, it all depends on this issue on the voltage. Although the depth can be slightly reduced, by about half a meter in a area located five meters before entering the building. In addition, it is possible to reduce the depth due to the intersection with other underground utilities, but in this case it is necessary to protect the cable with a pipe, since even at a low depth, mechanical damage may appear.
From the underground cable, the distance to the foundation of the home cannot be no less than seventy centimeters.
Cable laying under the basis is by no means to be carried out. Paying a cable on a garden plot, you need to know that the minimum distance from the trunks of trees to the cable should be two meters. Although it is possible to reduce such a distance when mounting a cable in pipes by digging. In this case, you can reduce the distance of eighty centimeters, if you use the sold desalfents manual and electric.

Intro text
Before starting the construction of the building, you should think over the sewage system and water supply system.
Each object, whether it is a residential building or a public building with an adjacent territory needs good street lighting, as well as architectural backlight.
The beginning of any construction is the construction of electricity to the construction site.
