An earthing kit for a private house is required to ensure the safe use of electricity.
Earth Scheme Design
The grounding scheme of an individual building consists of four components:
- unit that consumes electricity;
- distribution board with neutral bus;
- ground conductor;
- artificial ground electrode.
Choice of tools and materials
Electrically educated people can mount the grounding themselves. But the ladies will have to hire performers: three-quarters of the work requires the use of male force.
Tools and accessories for grounding device:
- Bayonet shovel for digging trenches 70 cm deep and 50 cm wide.
- Steel sledgehammer for driving pins to a depth of 2 meters. Weighs from 2 to 16 kg.
- Bulgarian for cutting metal into fragments weighing 3-5 kg.
- Perforator for installation of ground electrodes. Weighs from 2 to 12 kg.
- Welding machine for joining rebar and plates. Weight - from 8 to10 kg.
- Wrenches for tightening bolts.
After completing the inventory of the tool, pick up the consumables. Five items required:
- Bolt M10 or M8. Prepare both options, the leftovers will come in handy on the farm.
- A square of copper wire is selected according to the cross section of the phase conductor. Its length is equal to the distance from the installation point to the porch of the house, its thickness is six millimeters.
- Strip of stainless steel 40 by 4 millimeters and length from the mounting point to the porch of the house.
- Strips of metal under a triangle with parameters 1200 x 40 x 4 mm.
- Stainless steel corner with dimensions 2000 x 50 x 50 millimeters. If there is no corner, it can be replaced with reinforcement.
Building supply stores offer a ready-made earthing kit for a private house EZ 6. The composition 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 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 way. The composition includes four rods of 1.5 meters each, a mounting dowel and a clamp to attach the conductor. The choice of component materials depends on the financial condition of the developer.
Ground Loop Route
The place for the grounding device is chosen taking into account the low traffic area. If the wiring breaks and protectionworks, then negative consequences are possible, up to death for all living things in the area of the grounding. It is best to locate the outlet 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 arrange a rock garden on the protection zone. No one will try to walk on the boulders.
The choice of the ground loop depends on the availability of free territory: line, triangle, rectangle, 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. The 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 then be closed.
Installation operations
So, the place is chosen, the ground loop is defined. It remains to correctly mount the grounding kit for a private house.
- Earthworks begin. They dig two trenches: one in the form 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. The waste soil is left in place for sprinkling the finished structure.
- We drive the electrodes to a depth of 2 meters. Depending on the density of the soil, we use a sledgehammer or a perforator in the “hit” mode. With rocky soils, you will have to invite a drilling rig. If the pins are from the profile, then it is better to use a grinder: cut off the driven end obliquely. It is necessary to drive in the pins so thatat the top there was a part sufficient for welding the jumper plates.
- Weld one end of a long plate to the top of the triangle and lay it in a straight trench.
- The cable is attached to the plate with a bolt.
- Before filling the trench, measure the resistance of the mounted structure. Testers are welcome. But it is not practical to buy specially, as the devices are expensive.
Let's give a proven method. We connect one contact of the light source (lamp) to the phase, and the second to ground. Result and output:
- bright light - correct installation operations;
- dim light - joint rewiring required;
- lack of light - work done wrong, 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 driven into the ground, as well as the disgusting quality of copper plating, which leads to accelerated corrosion of the pins.
