Whose got the pic of an earth rod in a bucket of sand?And if it's a 10th floor flat, what then?
Is it Christmas yet.
That's the question my boss asked, what happens if it's a flat. Do you think the extra cost of having to add an earth rod will put people off having a board change or will more people be looking for a cowboy to do it cheaper[/QUOTE]
Sarcasm? I am confused by your comment, either your just been witty or you don't understand when and why bonding is required.With all the movement to plastic piping now,
Ensuring good earthing by using a ground rod
May well be a good move !
I was refering to using a ground rod NOT bonding !

How many electric cars need to climb 10 floors to be recharged?And if it's a 10th floor flat, what then?
I more or less had to refuse exactly that request recently. It's going to get more common, and especially with hybrids which only need small charge off 13A socket, hard to draw a line against the regs.Potential Customer has asked me to put a power socket on the outside wall of his garage, what's it for I ask conversationally "its to charge up my hybrid"... PME, so IET Code of practice recommends min 2 by 2.4m rods. Plus get it back to MET. I wish I'd just shut up.
.3, In situations where it is not practicable to install Earth electrodes and perhaps even in situations where it is practicable, should upfront RCD protection also be provided so as to disconnect the supply in the event of a supply Neutral fault?
No it would not be the property of the DNO, just as an upfront RCD for a TT Installation would not be the property of the DNO..
& This would need to be before MET then wouldn't it? - Thus the property of DNO ?
At present if there were a supply Neutral fault, the bonding and extraneous metal pipework would become the Neutral.Agree - If the neutral is lost surely we should isolate the installation not add rods so it can carry on in a busted condition ?
.No it would not be the property of the DNO, just as an upfront RCD for a TT Installation would not be the property of the DNO.
The RCD would be best placed after the DNO PME connection. It would then also operate in the event of an installation Earth fault.I think I get you now - the "upfront RCD" would have to be on the DNO side of the PME connection to work.
