Nobody knows everything ,and if they think they do they are normally full of .I think everyone feels a bit daft asking questions and being unsure in case they get a trolling,but its better to ask and get it right than to not ask and get it seriously wrong.

It's better still to ask before doing the install!!!!

The install was a rewire I have been put in this position by some one else I have come to test it and the earth was used off the old bonding pipe. I have done my best to rectify this I have rung the electricity board who would not earth the house leaving me to put an earth rod in I have gone well be on the means to get it done properly. I am not apologising for asking a question about a tt system I no electricians who no most thing about the regs and I have a good understanding , they couldn't help me and the one that has tried has given me wrong information which some people have jumped on me for.
