Plus also then ignore any paperwork supplied by electricity boards requiring this bonding lark to be carried out. They don't know what the hell they are on about. Enjoy your shocks in comfort. Remember DIYers know best. With that I'm out, as they say on that show.

No I was refering to the copper discharge pipe from an unvented cylinder to ground level ot into a soakaway unit around 500mm from building wall. Even the all electric ones would only be installed by a suitably qualified person. Electrician would only be involved wiring the immersion heater...

Lets be sensible for a moment! I can give you scenarios easily enough then you decide where the difference comes from. For the moment I'll go along with the no bonding concept for the moment. 1. Plumbing Common fault I used to go to plumbing wise was the replacement of immersion heaters in...

Ok I conceed I am wrong the whole world, same equipotential bonding requirements apply around the world, is wrong the people (well 3 of them on here are totally correct) Their executive decision that the concept of bonding everything was a myth (well apart from those that have confirmed being...

I can also remember being caught up in that fiascio but only in the case of sinks and waste supplies. Sink manufacturers even welded on earth srtaps. to assist. Just remembered there was a company that developed pipe fittings that were made with welded of formed terminal fo use under boilers...

And a final note on wiring regs isn't it about time they had some true legality? At the moment they compleatly lack any authority which applies to anyone calling themselves an electrician. All you can do if you find a dangerous situation, even if life threatening, is issue a warning note to...

Disagree really. Sorry meant to include this also: I take that to refer that Extraneous-conductive-part is a conductive part that is ouside of the electrical installation, eg a pipe that may, or may not enter from the outside which may produce a potential difference between the electrical Main...

A explaination of the current regs, the way I interpret them, and the way things seem to have been done and why. (Every quote from 17th edition - yellow. For wiring regs.) Firstly what is meant by an equipotential zone? According to On Site Guide Me: Sinply states metalwork Forget what any...

I have not seen a copy of the 18th besides they are not in force until January. Agreed they can be used already and probably the past six months so noway can they explain current installations compleated for the many years until now.

I keep trying to explain. Going to take dogs out then I'll try again! Plus I'll try to find some other images to prove the point I am trying to make.

Rocky just maybe tou are begining to see what I have been trying to say. How can you admit that one? I was shouted down good and proper earlier for saying just that!

Rocky your inage 3 is closest to being correct so far

Then he would be breaking the rules.

What the gas pipe or water pipe? Plus trying to work out what that fitting is within the trunking. Thinking plain union or filter to catch black dust (common particually in copper pipes) or just plain debris from main. At the moment compleatly worn out will respond fully later.
