In accordance with the German standard DIN 18014: 2014-03 Fundamenterder – Planung, Ausführung und Dokumentation (Title Englisch: Foundation earth electrode - Planning, execution and documentation), foundation earth electrodes have to be connected every two meters with the foundation plate. Among the various connection possibilities the clamping connection has turned out to be the most economic, as it can be realised fast and easily on site.
Among others also reinforcing steels shall be used as natural components of the down conductor system according to the current lightning protection standards. In the following a survey of the nominal and outer diameters as well as cross sections of the reinforcing steels DIN EN 10080: 2005 (see Figure 1).

For fast and easy installation. As shown in Figures 2 and 3 they can be used as connecting and fastening element for fixed earthing terminals as well.
Optionally, this new type of connecting clamp also allows to use cable lugs for a flexible connection, as shown in Figure 4.

Figure 5
The already practice proven connecting clamp for T, cross and parallel connections has been equipped with an additional clamping frame. Thus, as Figure 5 shows, both, the electrical contact between reinforcement steel and fixed earthing terminal and the mechanical fixing in the formwork is realised. This clamp may also be used for the T or cross connection of a round conductor.
