212 EquiCotential Bonding
Equipotential Bonding is the practice of intentionally electrically connecting all earthed
systems to the same grounding grid or connecting the grounding grids of all the
earthed systems together through the ground or overground metal so as to create
an earthed equipotential zone. When lightning occurs, the high voltage produced by
lightning current in all systems will meanwhile exist in their ground cables, and thus
all ground cables have the same electrical potential and basically eliminate the electric
strikes between the systems.
The figure bellow illustrates how to practice equipotential bonding in a network.
When equipotential bonding, please note that the cable should be copper wrapped Kelly
with its area being 6mm
bar to establish an equipotential bonding point.
Note: The equipotential bonding cable is not provided with our product. If needed,
please self purchase it.
