41、cal installation of the building. Thus, the electrode is part of the electrical installation as set out in the Niederspannungsanschlussverordnung. The foundation earth electrode serves to provide continuity with the earth in order to permit protective measures to be taken with regard to the electric

42、al installation, conduct any earth fault or protective conductor currents to the earth without this causing undue thermal, thermomechanical or electromechanical stresses or give rise to electric shock, originating from such currents, permit any functional requirements to be satisfied. As defined abo

43、ve, foundation earth electrodes are electrodes embedded in concrete. If, for structural reasons, a concrete foundation is to have an enhanced earthing contact resistance, the electrode is to be installed in the surrounding ground and then termed “ring earth electrode”. Criteria for selecting the pro

44、per type of electrode are found in Annex B (informative). DIN 18014:2014-03 8 4.2 Protective equipotential bonding via the main earthing busbar A foundation earth electrode improves the effectiveness of the protective equipotential bonding. It is to be connected to the main earthing busbar. Where a

45、ring earth electrode is installed outside the foundation, it is necessary to provide an additional functional bonding conductor for potential grading within the foundation. 4.3 Functional equipotential bonding 4.3.1 EMC requirements A foundation earth electrode in conjunction with an additional func

46、tional bonding conductor ensures functional equipotential bonding to comply with EMC requirements. 4.3.2 Lightning protection systems Where lightning protection systems are to be installed, additional measures as detailed in the DIN EN 62305 series of standards (VDE 0185-305) are to be taken. 5 Exec

47、ution 5.1 General Foundation/ring earth electrodes shall be installed as a closed loop. Where larger buildings are involved, the electrodes shall be meshed. The mesh size shall not exceed 20 m 20 m. Smaller mesh sizes may be required if the electrodes also form part of a lightning protection system

48、(see DIN EN 62305 (VDE 0185-305) series). Where buildings are subject to particular requirements (e.g. buildings in which IT equipment is installed), additional measures (e.g. those detailed in DIN EN 50310 (VDE 0800-2-310) may have to be taken. For power installations with rated voltages exceeding 1 kV a.c., the specifications of DIN EN 50522 (VDE 0101-2) and DIN EN 61936-1 (VDE 0101-1) shall also be considered.
