Exporting the earth?

[antimatter]

From the IET's many threads on this subject

"Generally speaking the exportation of a TN-C-S supply is the decision of the local DNO and only done with their permission. In the absence of such permission it would be recommended to use a TT system and RCD protection.

Well as I can supply you with a wealth of evidence to the contratry, could you please supply me with some evidence to support your statement.

can you prove this please with some regs... i still disagree

 

[antimatter]

was saying you can connect an outbuilding to a PME system as long you earth it accordingly. Alternatively you keep it seperate and TT it.

keep it seperate and TT it

How many times does it have to be pointed out!!!!!!!!!!!!!! Where does it say that you can not export a tncs earth? if you can not provide that proof then you are wrong!

Far too much Miss-information and too many scaremongers in the UK with regards to PME installations. You would think that after all these years of the system being supplied by one form of supply authority or another that it would be far better understood. You just don't get this hostility towards PME/TNC-S in other European countries!!!

Perhaps these unbelievers should remember, that all those old TT systems (many going or gone bad) were converted to PME, and for a very good reason. It took years getting these installations a decent earthing system. Now it seems, these people want to return to the bad old days, and whack in Rods willy nilly, not really knowing or understanding what they are actually doing. Who is going to maintain all these TT systems, certainly not the electrician that installed them... Oh, i forgot there is always that RCD, ......So no problem ....NOT!!!!

You are wrong for saying you can export the earth on a TNC-S system.

I would be interested to learn why my attitude is poor if you are calling what i write rubbish.

Antimatter,
can I ask then, if you are installing outside lights or sockets wired to the main building which is on a TNCS....do you rod them individually,and separate the earth....or use the TNCS?....I ask because logically if you are so appalled by the thought of a shed on a TNCS then presumably you feel the same about an outside light?.....if not why not?

Because you can not back up what you say!!!

 

[Deleted member 9648]

Actually I'm coming to the conclusion that this is a wind up......is he off the plumbing forum?

 

[antimatter]

Yes I can and I already have, just because you insult me when you are trying to make your point, doesn't make you right!

Wow missed all this just go to show you what happens to a thread when you leave it. Not sure if you read my post #12. The Electricity supply Regulations did cover PME as a section, well the SEEB ones did, and this is where the exporting the earth debate originated.

Just read engineer54 part about TT without RCD protection, blimely he must be older than me becasue I remember using the fore runner of the RCD which was the ELCB back in the late 60's when I started out, and I think it was in use as early as the 60's and even the late 50's

This statement doesn't say you can't use it, it says you have to contact your DNO. That doesn't make it a no no. The DNO go by BS7671 just like us and will most likely say yes. What reason wouldn't they.
But in the absence of the permission, you than have a CHOICE of a TT.
I can't see this statement supporting the prehibitation.

You clearly have not produced anything to prove a tncs earth can not be exported
