[Jcamerz]

Hi guys new to the forum after bit of advice. My family are installing a new shed in the garden and require a lot of power ie few sockets, lights. I am planning of running a swa fed from 32a mcb from the main board to a sub board.
Have a question-

Thanks

No Murdoch they are real Regulations, not clauses.
If you have access to the internet, which you obviously do, then you can look this up.

What absolute carp.

Proper regs numbers to back up your somewhat dubious claims please

Or do we need a new rating “fake reg”

Murdoch they are proper regulation numbers, you are now just showing your ignorance.
BS 7671 is not the be all and end all.
These are the Regulations that you will be prosecuted under.
BS 7671 is your Regulation 29 defence if followed.

Try the LAW.

Try the LAW.

Hum ...

I think you need to calm down and go back and answer the original point again.

There is no law stating that swa must be earthed at the supply end ...

The question was what is the BS 7671 reg number that you believe refers this to

Gawd this is like watching an impending train wreck.

No your question was, what REGULATION, you actually said in post #23 "Reg number please"
Which I then gave you and since then you have been disagreeing with me.
You said NOTHING about BS 7671, you asked for a Regulation, not a clause in a standard.
Remember, Regulations are law, BS 7671 is a standard.
The numbers I quoted are the law that you would be in breach of.
Try THE, Electricity At Work Regulations 1989 (As Amended).
Also if you want clauses from some industry guidance try...
522.6.201, .202, .203, .204
522.8.10
543.3
IET GN8 guides you to EAWR on this topic just for your guidance.

 

[netblindpaul]

Oh and just for your delectation 134.1.1

 

[netblindpaul]

Also 510.3

Is it not just common sense that it should be earthed at the supply end? What if it got severed completely and then re-energised, the armour would not be earthed. Mind you round here there is loads of it not earthed at all, seems to be a bit of a blind spot with a lot of contractors.

A disagreement is merely an opportunity to learn something new! I certainly did, not sure about anyone else..

The EAWR does not apply to a domestic installation.
SWA should be earthed, otherwise it won’t work as designed.
It should a earthed or connected to the same earthing system as used by the protective device protecting the SWA.
Connecting the armour to one of the cores at the load end of the cable would require the Zs measurement would have to be taken at the supply end of the armour.
Not sure whether the Zs would then be low enough for the protective device to operate?
