A grounding kit for a private house will save a life

A grounding kit for a private house is necessary to ensure safe use of electricity.

Grounding scheme design

The earthing scheme of an individual structure consists of four components:

• the unit consuming the electric power;
• distribution board with zero bus;
• earthing conductor;
• artificial earthing switch.

Selection of tools and materials

People who are educated in the field of electrical engineering can mount the ground independently. But the ladies will have to hire performers: three-quarters of the works require the use of male power.

Tools and arrangements for earthing equipment:

• Shovel bayonet for digging trenches with a depth of 70 cm and a width of 50 cm.
• Steel sledgehammer for clogging pins to a depth of 2 meters. Weighs from 2 to 16 kg.
• Bulgarian for cutting metal into fragments weighing 3-5 kg.
• Hole punch for earthing. Weighs from 2 to 12 kg.
• Welding machine for joining reinforcement and plates. Weight - from 8 to 10 kg.
• Wrenches for tightening bolts.

After completing the inventory of the instrument, select consumables. Five elements are required:

• Bolt M10 or M8. Prepare both options, the leftovers will be useful in the household.
• On the cross-section of the phase conductor, the square of the copper wire is selected. Its length is equal to the distance from the point of installation to the porch of the house, the thickness is six millimeters.
• Stainless steel strip 40 to 4 millimeters and the length from the point of installation to the porch of the house.
• Strips of metal under the triangle with the parameters 1200 x 40 x 4 mm.
• Corner of stainless steel with dimensions of 2000 x 50 x 50 millimeters. If there is no corner, it can be replaced by a reinforcement.

In building supplies storesoffer a ready-made grounding kit for a private house EZ 6. The structure includes four 1.5-meter long bars covered with copper, and four couplings. In addition, the kit contains a tip, a head and a rod clamp, as well as an anti-corrosion tape and a conductive paste. The kit is mounted using a sledgehammer in soft ground conditions.

ZZ 6 - kit for earthing a private housein a clutchless manner. The composition includes four 1.5-meter rods, a mounting nag and a clamp to attach the conductor. The choice of components depends on the financial state of the developer.

Ground loop path

Place for the grounding device is chosen taking into accountlow patency of the site. If the wiring breaks and the protection is triggered, there may be negative consequences, up to a lethal outcome, for all living things in the grounding zone. Dispose of the tap is best at a distance of one meter from the foundation of the house. It is unreliable to build fences around the canal. It is more practical and practical to arrange a garden of stones on a strip of protection. No one will try to walk on boulders.

The choice of the ground loop depends on the availabilityFree territory: a line, a triangle, a rectangle, an oval. The arrangement of pins in a row according to the principle of a Christmas tree garland requires less space, but the amount of installation work will remain the same, and reliability will decrease. Failure of the first jumper will lead to the inoperability of the entire system. The optimal shape of the contour is a triangle when three pins are driven in. The system will be closed at the same time.

Mounting operations

So, the place is selected, the ground loop is defined. It remains to correctly mount the grounding kit for a private house.

• Earthworks begin.Two trenches are digged: one in the form of an equilateral triangle with an edge of 120 cm, and the second one should be laid from the top of the triangle to the porch of the house. The spent soil is left in place to cover the finished structure.
• We drive the electrodes to a depth of 2 meters.Depending on the density of the soil, we use a sledge hammer or perforator in the "impact" mode. With rocky soils you will have to invite a drilling rig. If the pins are made of profile, then it is better to use the bulgary: to cut the butt end obliquely. The pins must be driven in such a way that there remains on the top a part sufficient for welding the jumper plates.
• We weld one end of the long plate to the top of the triangle and lay it in a straight trench.
• We fix the cable to the plate with a bolt.
• Before pouring a trench, measure the resistance of the mounted structure. Availability of testers is welcome. But especially to buy is not practical, since the devices have a high cost.

Here is a proven method. One contact of the light source (lamp) is connected to the phase, and the second to the ground. Result and output:

• bright light - correct installation operations;
• dim light - re-installation of joints is required;
• absence of light - the work was done incorrectly, maybe from the very beginning - from the project

Reviews about the grounding kit for a private houseEZ 6 are different. Professional installers and skilled craftsmen note the excessive flexibility of structural elements when driving into the ground, as well as the disgusting quality of copper plating, which leads to accelerated corrosion of the pins.
