Ringerder, where is the best place to install it?

Without sound knowledge of standards, one is according to my interpretation of the official definition according to DIN VDE 1000-10 no electrical specialist.

However, as an electrical engineering graduate engineer, I am also not a layman, but even according to DIN VDE 1000-10 (VDE 1000-10) an electrical specialist and aware of potential dangers.

Since 2007-09, for the installation of grounding systems not only the qualification as an electrical specialist but - as for other electrical installations - also an entry in the installer directory of a VNB is required.

It will probably not be worse than usual when installed by bricklayers or electrical specialists, of whom only a few exotic ones really know DIN 18014:2014-03. Even as a graduate engineer for electrical engineering, one should have read it.

DIN 18014:2014-03 costs €94.10, cheaper is the mandatory reading according to the Federal Installation Committee, the standards manual for electricians for €82.00.

7.3 Continuity measurement

The continuity measurement between the connection part for the main grounding bar and all other connection parts must have a resistance value according to 5.8 of ≤ 0.2 Ω. Measuring devices according to DIN EN 61557-4 (VDE 0413-4) must be used. The continuity measurement must be carried out before the concrete is poured.

NOTE The measuring current according to DIN EN 61557-4 (VDE 0413-4) within the minimum measuring range is 0.2 A.

It goes without saying that a multimeter is not sufficient for this.

Favor electricians who bless grounding systems they have never inspected in the meter registrations as compliant with the standards are, as known, always to be found.

Grin... that is why here now, deficiency reports threatening "service shutdown" are also issued more frequently.

I would rather say you meet the requirements for an EFK. In which field do you work as a Dipl.-Ing.?

I work in the embedded sector. By the way, aside from the electrical side, V4A steel in 10mm is not easy to bend straight again from coil form. Do you have any good tips on how to straighten the wire without a wire straightening device / straightening rollers?

Working in the embedded sector.

This also does not replace the required entry in an installer directory according to NAV § 13. Once EFK always EFK – moreover for all areas of work – is no longer valid. It is certainly not in line with DIN VDE 1000-10 that one obtains the missing experience from forums before starting work.

If the regulations on knowledge of standards and further training were seriously enforced, there would be an exodus on construction sites.

...V4A steel in 10mm is not easy to straighten again from roll form. Do you have any good tips on how to straighten the wire without a wire straightening device / straightening rollers?

In contrast to visible steel catch and grounding conductors or ductile aluminum wrought alloys, the residual waviness of NIRO ring conductors in the ground is completely negligible.

Work in the embedded sector.

Then you are only responsible for the EFK area.
