The order of the ground loop installation for private homes

To create a full-fledged living conditions in a private home, you need to take care of its electrical safety.To this end, in addition to lightning, at the design stage, need to provide the installation of grounding devices.Self assembly of a private home ground is not of itself any difficulties, compared, for example, devices for high-rise buildings.

grounding path for a private home is usually done in the form of a vertically driven into the ground pins, interconnected by means of horizontal earth electrodes and, with the help of a conductor connected to the electrical panel.

vertical grounding, as a rule, are made of steel parts with dimensions of 5 cm × 5h0.5. Horizontal same grounding can be made of flat steel dimensions of 4 × 40 mm.Explorer most often made of round steel bar cross section 8-10 mm2.

Structurally decided to carry out ground loop in the form of an equilateral triangle.To this end, in the courtyard executed the corresponding markings.The very same circuit ground rules recommended to have no more 1 meter from the building foundation.

After markings made on the perimeter sees a trench depth of about one meter and a width of 50-70 cm. The trench that is intended for the construction of horizontal earth electrodes.

Further, on the heights of the triangle should be to drive vertical grounding pins (to a depth of 2-3 m).Pins can drive with the help of the usual sledgehammer that in the case of use as a pin corners, is not difficult.To facilitate this process, the corners at the ends can be sharpened grinder, then it is easier to enter the ground.You can so the same dig or drill small wells approximately one and a half meters deep, then the drive will have a smaller layer of soil.

After all the preliminary work, site selection, layout and production of digging the trench can proceed to the very installation of the grounding circuit.On the tops of the trenches in the ground are driven corners, but not completely, and so that the trench acted 200-250 mm corner.

After will be driven into the vertical part of the loop, they must be connected to each other by means of horizontal earth electrodes, creating a closed circuit.Usually, this is done by welding, privarivaya band to projecting corners.Joining the corners with the band only needed by welding, bolting for this use is not allowed.

After assembly of the earthing circuit, it must be connected to the electrical panel.To do this again need to use welding.earthing conductor (wire made of steel 8-10 mm in diameter) must be welded to the circuit, and then lay it in the trench to shield.At the end of the wire by a shield welded M6 bolt (M8) intended for fastening the ground wire.

In the absence of a steel wire as a grounding conductor, the steel strip is permissible use, such as used in the manufacture of horizontal earthing.
