How to make ground with their hands?

If in the last article, we looked at 4 different circuit arrangement of the ground in a country house, but in this material in detail consider the scheme in the form of a triangle with the pins at the vertices. Such a scheme is the most simple to manufacture and installation, for which he is most often found in cottages.

What material is used for the electrodes?

- steel corner width at least 4 × 4;

- fitting section 10-12 mm;

- a pipe with a thick wall section from 3 to 5 mm;

- the steel strip 50 mm wide.

An important tip!

To get the best possible contact with the ground electrode choose not corrugated and smooth fitting. When you score a rebar into the ground around it there are voids, reducing the efficiency of the grounding. Optimal probe length - 3 meters. Used for binding the metal strip section 4 × 40 mm, or the diameter of armature 14.

The sequence of work

First, select and clear the space at the site, which will be installed ground loop. The ideal distance from the electrodes to the power cabinet - 10 meters.

Digging a trench similar to the strip foundation, but in the form of an isosceles triangle. The depth of the trench - 1 meter width - 0.5 meters. The optimal distance from the rod to the rod - 1.2 meters.
One of the closest to the angles of a triangle house dig a ditch visor.

The vertices of the triangle are hammering vertical reinforcement.

Driven into the ground rods must little peek at the surface and connected bus. Welded to the rods driven into the harness, closing the triangle. From one of the electrodes are conducting strip along the trench to the distribution box. The conductor is fastened to the shield via a welded bolt.

Ohmmeter check the resistance. If the figure does not exceed
4 Ohm, Thrush can be covered with soil. If more, then it is necessary to hammer into the ground a couple of electrodes and connect them tires.

Following the work carried the risk of reduced tenfold.
