[QUOTE="Sidewinder, post: 457812, member: 9512"] No Phoenix, you are spot on mate. Apart from one comment, wrt the base of the columns. They are more often than not so well corrosion protected, they are totally insulated from the ground around them when new. That was a big surprise to me, I always thought that they would be a great big earth electrode, but due to the anti-corrosion measures being insulating, they are nothing of the sort! Drop a rod adjacent to avery fitting if you can, and ensure that the CPC is a good CSA joining everything together, ideally TN-C-S sized, and that will help. [/QUOTE]
