Before the thunderstorms come … I attached the ground cable yesterday, as recommended. The datacenter is attached to a tube at a height of around 3.5 meters. This is not that high, but we already had a lot of lightning strikes nearby and once several electrical devices were damaged in a flash. So I feel safer. The cable was not cheap, about $ 60 for 4 meters. The prepared connection clamp at the Datacenter made the installation easy

Proper grounding is definitely important.

Mik, what did you do at the other end? For lightning protection I would think a connection to a 6 ft ground rod (or Ufer ground here in the USA) might be a good idea.

Thank you for sharing your experience. Installing a grounding cable is especially important in regions prone to lightning. Your proactive approach definitely adds an extra layer of safety.
Hello offgrid,
thanks for your question. I had an iron bar of about 2 feet. After I saw the question, I searched for information again on the Internet and found that my solution was bad. So now I have driven a galvanized water pipe of more than 7 feet into the ground. The garden is very damp underground. Maybe not perfect but better than nothing

Ground water is gonna be conductive due to the minerals and salts in the soil, so not sure where you are located, but for our locale, Pacific Northwest, generally that depth is “good enough”.
Nice job and the joins look well done. Because of dissimilar metals, I would spray some stuff over the connections to prevent corrosion. Just about anything works, I’ve used vaseline, lithium grease, spray paint, antioxidant paste, you name it. Anything that keeps oxygen and moisture at bay works fine.
Oh looking at the pic one more time, I see the copper wire to be in contact with some washers, which are in contact with some nuts, so the conduction path is through the nuts. There are a lot of surfaces to corrode between the wire and the pipe… but then again if all the hardware is stainless, it’s probably ok, because if they are all airtight joints, covered with anti-corrosion stuff (paint) they will likely not corrode much over their lifetime. Sorry for going on…could not help it!
