Making the ground in a private home, step by step guide

So you want to change in your home the old two-core wiring for the safe three-wire or bought a house or cottage, which also require this same procedure. Do not forget to also take care of the quality of the grounding loop. You do not know how to do it? It does not matter in this article I have are all very detailed and clearly explained.

What is it for

Before proceeding to the description of the circuit mounting process, I want to say a few words about the need for this action to have any shadow of doubt remained about the feasibility of this work.

I'm not going to paint the technical requirements, but I will say simply: the presence of this circuit will save your life in the event of failure of any electrical appliance or damage to the insulation of your three wire network.

What it is in contour

I hope I have convinced you. Let's get started. The entire protective circuit is composed of two parts: in-house and street. And the area of ​​differentiation is a bus in the distribution board, onaya looks like this:

Choosing a scheme

Now, there are several variants of the grounding circuit

But I recommend using a closed loop in the form of a triangle, and here's why: Using exactly loopback system increases the reliability of the circuit several times, as in the case of damage to one of the pins, a large part of the circuit still remains in operation, and in a linear arrangement, if the band break off at the beginning of loop, we completely lose ground.

Just delta less material is needed than for example in a square. Thus, the scheme chosen, continue.

Cooking equipment and material

For the successful execution of the work you will need: svarochnik, Bulgarian, shovel, hammer, heavy sledgehammer and a set of keys, control print.

Prepare materials:

Three pin length of at least 2 meters (suitable fittings 16, Area 50x50 or steel pipe with a diameter not less than 32 mm).

Strip 40x4 mm in length by at least 110 cm and another band of the same parameters, but you need to choose the length of this, to have enough space on the system circuit to the house wall.

Bolt, the more the better.

And flexible copper solid wire section is not less than 6 mm square.

All of this gathering, you can safely get to work.

editing process

During the selection of the installation site, try to place it as close as possible to the distribution box. Because in this case, running the following principle: the smaller the length of the conductor, the more effective grounding.

Then you need to dig a trench wall to dig a triangular contour and contour and all this at a depth of not less than 0.7 meters.

Then take a bath or reinforcement (pre imprisoning one end for better passage of the soil) and trying to drive it in depth. In this case, on the surface, leave for 15-20 centimeters.

After that, we take the strip and weld our triangle. In this case, note that the weld you must be at least 10 cm.

Then to one of the vertices of our triangle welded to each band onaya will have to go to the wall of our house.

In this case, the weld should be treated with any anti-corrosion compound. But the resulting paint to paint the design strictly prohibited.

After that, at the end of the band we fasten our bolt (it can be either welded or drilled strip and simply insert), with the help of which is attached has a copper wire, which already goes directly to the shield.

But do not put it on the bus, let's first check our circuit. In good need to call a professional and have it with a special instrument will determine the loop resistance. But you can go the other way. Take normal kontrolku into which lamp is inserted at least 100 watts and a nominal value at one end of the planting phase and the other in our grounding wire. If the lamp lights up with bright light, then everything is fine. If not, then somewhere in the loop there is a break, and it is necessary to find and eliminate.

Making sure that everything is done properly plant the wire on the ground bus in the panel and fasten it already ground, running with the rooms.

And on the street and we give all bury the infield in order.

And so it happens installation of the grounding circuit in a private home or cottage. As you can see, there is absolutely nothing complicated. Thanks for attention.
