There is only one ground electrode system in one installation site.

If there are several ground electrodes on the site (for example old and new installations), bond the ground electrodes together to prevent dangerous potential differences during a lightning strike.

In general, ground electrode construction and shape depends on soil type.

To disperse the electric current to soil, two main electrode types are used:

  • Ground rods
  • Horizontal ground electrodes

Depending on the site, use either one type or both to complement each other. You may also use conductive plates and wire grids.

A typical ground electrode system consists of several horizontal and possibly also some vertical ground electrodes.
