NEW EHU BOLLARDS.

[Dustydog]

I discussed this issue with a retired spark mate.
He first experienced it years ago when they were connecting mains power to building site portacabins. People were getting”tingling “ whenever they touch metal cabinets inside the cabin.
He knew it was an earthing fault. Solution was a metal rod driven 2 metres into the ground, shingle is no good, and connecting it to the CU earth. Apparently he says this became standard practice.
He suggests I get a separate earth fitted at home .
What do you think or is it an over reaction🤔

Its exactly what I have, an earthing ground rod will cost you less than £10 from Toolstation or Screwfix, I connect it to the van chassis with a jumper (starter) cable, because its quick to clamp on to the earth rod and caravan chassis. An electrician would want a more robust way of connecting the van to the rod, so my solution is not 100% up to spec! but its good enough for me as a visual check confirms its all connected.

The biggest issue with an earthing ground rod is hammering it into the ground which can be a bit challenging for some people. Done plenty when I was younger as it was mandatory if you erected an outside TV aerial. Probably why I am suffering with my wrists now.

If you have an SDS drill, there a re a couple of options, firstly you can get an attachment that enables you to use the drill in hammer only mode, the drill then does the work, or get a 1000mm long SDS bit that has a smaller diameter than the rod, drilling a "pilot" hole makes it easier to drive the rod in.

Why the caravan rather than the house CU? I was thinking of a more permanent fix rather than another cable out of the caravan?
