Introduction Earthing
Furse earthing components are manufactured to meet exacting British, European and international
standards to ensure robust, long lasting performance in even the harshest soil conditions.
All components are designed to withstand mechanical damage and the thermal and electromechanical stresses
from the earth fault and leakage currents expected within an installation.
Furse high quality earthing components have now been installed in, and continue to be specified for, many low
voltage and high voltage earthing installations worldwide.
Earthing products shown in this catalogue include where appropriate a range of quick reference icons to define
their conductor compatibility, installation requirements and their testing standard.
These icons, as well as a sample product page, are shown below.
The icon bar above each product defines the appropriate main conductor system to which the product can be
connected.
Therefore, where items , , are highlighted in full, the product is suitable for connection to the main
conductor system shown (see below).
Icons defining installation requirements and product testing feature under the product text.
These are shown in the example below, and on product pages as - testing standard, - fixings required, and
- torque setting.

Special component design and manufacture
For the vast majority of installations, the standard range of earthing components is highly suitable for completing
an earthing system. On occasion however, an installation may include a special requirement needing a non-
standard component.
Where this is the case, our technical services team can develop and design a special component to customer needs,
which on approval can be manufactured in the quantity specified for the project. For further information, or to
discuss a particular project need, please contact us.
Designed for connection of flat tape conductor to an earth rod.
Corrosion resistance, conductivity and mechanical strength are essential
considerations in clamp design to ensure an earthing system remains
operative for many years. All Furse earth rod clamps have high strength
copper alloy bodies and screws e.g. aluminium bronze, phosphor bronze
etc., commercial brass is not used.
