A grounding kit for a private home is essential to ensure the safe use of electricity.
Grounding Project
The grounding diagram of an individual structure consists of four components:
- unit consuming electricity;
- switchboard with grounding bus;
- ground conductor;
- artificial grounding.
Tool and material selection
Educated in the field of electricians, people can mount the grounding on their own. But the ladies will have to hire performers: three quarters of the work requires the use of male force.
Tools and devices for grounding device :
- Bayonet spade for digging trenches 70 cm deep and 50 cm wide.
- Steel sledgehammer for driving pins to a depth of 2 meters. It weighs from 2 to 16 kg.
- A grinder for cutting metal into fragments weighing 3-5 kg.
- Rotary hammer for mounting grounding conductors. It weighs from 2 to 12 kg.
- Welding machine for connecting fittings and plates. Weight - from 8 to 10 kg.
- Wrenches for tightening bolts.
After completing the inventory of the tool, select the supplies. Five elements are required:
- M10 or M8 bolt. Prepare both options, the leftovers come in handy on the farm.
- The cross-section of the phase conductor selects the square of the copper wire. Its length is equal to the distance from the installation point to the porch of the house, the thickness is six millimeters.
- A strip of stainless steel 40 by 4 millimeters and a length from the installation point to the porch of the house.
- Strips of metal under the triangle with the parameters of 1200 x 40 x 4 mm.
- Corner made of stainless steel with dimensions of 2000 x 50 x 50 millimeters. If there is no corner, it can be replaced by fittings.
Construction equipment stores offer a ready-made grounding kit for the EZ 6 private house. The structure includes four 1.5 meter rods coated 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
conductive paste. The kit is mounted with a sledgehammer in soft ground conditions.
ZZ 6 - kit for grounding a private house in a clutchless manner. The structure includes four rods of 1.5 meters each, a mounting bracket and a clamp to connect the conductor. The choice of components depends on the financial condition of the developer.
Grounding circuit
The place for the grounding device is chosen taking into account the low passability of the site. If the wiring breaks and the protection works, then negative consequences are possible up to a fatal outcome for all living things located in the grounding zone. It is best to position the tap at a distance of one meter from the foundation of the house. Building fences around the canal is unreliable. It is more useful and practical to set up a rock garden in the protection zone. Nobody will try to walk on the boulders.
The choice of ground loop depends on the availability of free territory: line, triangle, rectangle, oval. Arranging the pins in a row according to the principle of a Christmas 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 form of the contour is a triangle, when three pins are driven in. The system will be closed.
Installation operations
So, the place is chosen, the ground loop is defined. It remains to correctly assemble the grounding kit for a private house.
- Excavation work begins. They dig two trenches: one in the shape of an equilateral triangle with an edge of 120 cm, and the second should be laid from the top of the triangle to the porch of the house. Spent soil is left in place to sprinkle the finished structure.
- We drive in electrodes to a depth of 2 meters. Depending on the density of the soil, we use a sledgehammer or a perforator in the “blow” mode. With rocky soils, you have to invite a drilling rig. If the pins are from the profile, then it is better to use a grinder: cut off the obliquely driven end face. It is necessary to drive in the pins so that at the top there remains a part sufficient to weld the jumper plates.
- We weld one end of a long plate to the top of the triangle and put it in a straight trench.
- We attach the cable to the plate with a bolt.
- Before falling asleep trench, measure the resistance of the mounted structure. The presence of testers is welcome. But it’s not practical to buy on purpose, since the devices have a high cost.
Here is a proven practice. We connect one contact of the light source (lamp) to the phase, and the second to grounding. Result and conclusion:
- bright light - correct installation operations;
- dim light - requires remounting of joints;
- lack of light - the work was done incorrectly, maybe from the very beginning - from the project
Reviews about the grounding kit for a private house EZ 6 are different. Professional installers and self-taught 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.
