Install a Graounding

Essential to avoid any risk of electric shock or worse, electric shock, the grounding frees users to experience current leakage. According to the French standard, all new homes must be equipped with grounding. For older homes lack of grounding, it is strongly recommended to install one.

Tools and materials required

An insulated screwdriver.
An electrician’s knife.
Cutting pliers.
Wire stripper.
A voltmeter.
Screws.
A shovel.
A drill.
TPC sheath.
An earth conductor 16mm ² or section of 25mm ² copper or galvanized steel.
A bar of measurement.
A ground rod or loop to bottom of the excavation.
A box of cement cover.

There are two types of earth. The ground rod, often used, can be added to all types of construction. It is a galvanized steel tube of 25 mm thick and of variable length, averaging 1.5 m. It also uses the loop to bottom of the excavation, a more effective solution than the post but can be implemented only during the construction of a dwelling, which severely restricts its use.

Step 1: the burial.

When you realize the earth, the other end of the cable must not already be connected, and when you plug the other end, the circuit breaker should not be engaged (we work here on the safety!).
Push the stake about 2m deep in a healthy place close to home. The soil for the planting should not be too dry or stony (unless the post is longer: there are extended). Like any electrical connection, that the stake should be visited: the eye must never be rendered inaccessible (but it can be in the grass).
Support the stake out of the ground with the clamp and lock the cement in the box to isolate it.
The clamp should be protected tale corrosion. To do this, wrap the putty.
Take out a conductive sheath of the box.

Step 2: set the bar of measurement.

The bar is measuring the junction between the patch panel and the earth. It must be accessible and must only be disassembled with a tool. Secure it by screwing to the wall, 30cm from the ground, not far from the dispatcher and the earth.

Step 3: connect the earth to the bar of measurement.

Calculate the length of ground wire needed to connect the earth to the dispatcher.
Attach the wires to the connection and the plug with the screws provided for this purpose.
If the earth is too far from the wall, change the driver in a sheath TPC.

Step 4: Connect the card to the terminal distribution.

For this step, use a primary driver of protection, over-green and yellow 25mm ².
Strip an inch both ends of the conductor.
Insert one end of the wire in the terminal distribution and do the same for the other end by securing the space provided on the measuring strip.

Step 5: check the quality of your grounding.

You cannot see for yourself the proper functioning of your system, so you have to hire a specialist. It is prohibited to use as grounding water pipes, gas or central heating, and the metal sheathing for electrical continuity of the pipes is not always guaranteed, especially when problems arise in the electrical circuit.

If the quality of the earth is insufficient, it is possible to place one or two, spaced about 2 m, interconnected to improve it. The connection between the measuring point and the bar will be sharing the same section as the son of the table of power protection, with a maximum of 16mm2.
