New sub board for shed swa advice.

That DOES NOT answer my question, the question that has haunted this thread for pages

Please answer my question ......

That is the answer......134.1.1 and you don’t understand because you have’nt got enough experience or training. There’s only 2 places I can name where you insulate SWA from connection.

Using VSD’s
And leaving equipotential zones.

The question was and still is WHERE DOES IT STATE THAT THE ARMOUR MUST BE CONNECTED TO EARTH AT THE SUPPLY END

 

[bigbob1]

Sorry mate, but you have now gone beyond my simple mind. I've read the references you've kindly provided and I can't see a problem using an already in place TNCS/PME DNO cutout to supply the shed. No going to jail that I can see, provided it's done in accord with our usual BS7671. What have I missed ?

That ‘given earth’ is for ‘that equipotential zone’

You won’t understand because you can’t grasp the importance of an equipotential zone on a tncs supply. So I 100% know you will never understand. So will stop there with you.

 

[Deleted member 26818]

So where does it say in the regs you run can export the DNO earth?!

More importantly, where does it say you cannot?

Arrogant and extremely disrespectful !

Because it is in the HOUSE and running through the fabric of the HOUSE and in the HOUSE equipotential zone...because it’s an extraneous conductive part.....and not with a strap but with an SWA gland 134.1.1

Nothing more to say to you.

Look at that you are slowly working out how a ‘guide book’ works....

Now you’re being a dick.

The thing about Bigbob1 and his arguments, is that they are not based in fact and he cannot back up anything he states.
If a law of physics prevents us from doing something, permission from the DNO will not suddenly allow us to do it.
GN5 (although my copy is from 2004) makes no mention of us not being allowed to export any earthing system.
Same applies to ESQCR and EAWR.
In fact, ESQCR requires the DNO to allow me to export the earthing system, the only reasons they can refuse is if the installation does not comply with BS7671, is unsafe or if it might cause a disruption in network supply.

Look you clearly don't seem to realise [or care] that there are many well qualified,highly experienced and dedicated professional electricians on this forum. Nowhere has it been suggested using a strap instead of an SWA gland, although this was common practice for many years and I'd imagine considered acceptable at one time. Of course the armour must be connected to earth, you do realise that we're talking about situations where a seperate CPC is used within the cable ? But I still say that it doesn't state anywhere that the armouring MUST be earthed at the supply end. I've had enough of this nonsense now and won't post any more on this thread.

I think big bad bob has been educated beyond his intelligence, as a mate of mine used to say. he obviously does not operate in the real world, out there. The world of sheds, and things.

 

[Deleted member 26818]

Lol, don’t want to make a big thing about it, but it appears I’ve been a member for a lot longer than you.

It appears you are 2 digits short of an IET membership number. On your card what is your area number?

 

[sparksburnout]

Anyway where is this place we are exporting things to? Will we be able to export them when we leave the EU? Arghhhhhh..........
Or did you mean extending??

An extraneous conductive part in a house doesn’t need bonding to earth.......kind of invalidated most of your last and final comment.

My membership No. dates back to the IEE.

Oh you call it extending? How very modern.

 

[Dave OCD]

I'll have to reply again, what I'm saying is it CAN be connected to earth at the far end - as long as it's connected. You're clearly less intelligent than you think you are.
