Building lightning rod grounding wire through my bathroom underground, okay?
The earthing resistance of the lightning grounding device is less than 1 ohms. Lightning protection grounding is not isolated, grounding, work, grounding, protection, grounding, repeated grounding, equipotential bonding (and sub main equipotential bonding and auxiliary equipotential bonding), etc..
GB14050 "system grounding type and safety technical requirements" docking site has detailed provisions. For example, the teaching building can touch the water pipes, gas pipes, etc. have done, and other main potential link ground, but it is best not to touch when the thunder, huh, huh. Single building lightning protection, grounding and building adjacent to the best link, the more connected the better.
