2.28. GROUNDING CALCULATION
We consider that the land resistance is 300 ฮฉxm.
The electrode selected for the grounding are copper spades. It will be 10 spades around the
building. A naked copper conductor will join them all together to from an equipotential
bonding ring.
The spikes depth will be 2 meters.

To measure the ground resistance, is used the ground breaking box, that separates the spikes
and the protection conductors.
The protection conductors have been calculated according to ITC-BT-18.
