EARTHING POINT 205/B-M10-VA

Grounding rod 205 B-M10 VA. Purpose: connection point for the grounding system or connection from grounding to the main grounding bar using M10 x max.30 bolts. Can be embedded into a solid structure, e.g. concrete, so that the circular connection base plate remains on the surface of the structure and the 10 mm connection rod is reliably connected to the grounding electrode inside the structure. Material: acid-resistant steel; V4A, HST, 1.4404. For grounding, use RD 10 embedded steel; 10 mm diameter, 78 mm² cross-sectional area. The grounding system is part of the external lightning protection system, which conducts the lightning current to the ground and distributes it there. The most important principles for the even distribution of the lightning current without the formation of dangerous overvoltages are the shape and dimensions of the grounding electrode. Standard SFS-EN 62305-3 (IEC 62305-3) recommends as low a grounding resistance as possible < 10 ohms. The grounding system can be constructed in accordance with the methods approved by standard SFS 6000. It is possible to connect different grounding systems and materials together, but potential corrosion risks (electrochemical corrosion) must be taken into account. Grounding systems must be connected to the object's main potential equalization system. This product description is an automated translation of the original Finnish description.
