In the event of a short circuit, the carcasses of household appliances, the plumbing and central heating pipes, the metal frames of your home are excellent conductors: you risk electrocution. The only solution is to establish a circuit that drives the leakage currents to the earth to disperse them.
The principle is to connect all plugs and fixed metal elements to a ground circuit, itself connected to a conductor rod (galvanized iron) deeply embedded in the ground.
If it is preferable to pull the circuit to the garden, the stake can be planted in the basement, directly above the distribution board, provided the soil is permanently moist.
Prepare the floor and the duct
If the post is located under the feed table, break the slab with the chisel over its entire thickness. Seal PVC pipe 80 mm in diameter.
Push the earth stake
With a mass, plant the galvanized stake in the center of the PVC pipe. Regularly check its verticality. The stake must be depressed until it is flush with the ground.
Seal the PVC pipe
Seal the PVC pipe with quick setting mortar. Smooth the mortar with the cat tongue trowel. The tube protects the exit braid and serves as a well for moistening the earth.
Connect the earth
Engage a metal collar on the stake. Position the exit braid (bare copper) in one of the indentations of the stake. With a wrench, tighten the set screw.
