An earth termination network can be installed in different ways

1. Simple Earth Electrode

This can be a driven Earth Rod, an Earth Plate, a Mat or a length of buried conductor – or a combination of both.

From BS:EN 62305 . . .

For Lightning Protection, BS:EN 62305:3 advocates two types of Earthing System:

TYPE A – simple earth electrode
TYPE B – crows foot or counterpoise. These are ideally suited to areas of high soil resistivity and structures containing electronic equipment and hazardous materials.

Foundation electrodes may be employed – these are similar to TYPE B and are installed within the building’s foundation itself.

2. Crows Foot Electrode

Can incorporate Earth Rods – the rods would be spaced at least twice their driven length apart.

4. Grid Conductor

All circuits unless specifically designed for a non-conducting location will have a protective conductor ( PE ) included. They must be capable of carrying the maximum possible earth fault current to the DSO neutral, via the main earthing terminal.

They only have to carry this fault current for the time required to operate the circuit protective device. In general, this time will not exceed five seconds. In the event of a fault, they prevent exposed conductive parts becoming live with respect to earth.

The protective conductor may be a:

Separate conductor
Cable core
Cable armour
Metallic conduit
Metallic trunking
