New sub board for shed swa advice.

[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-
Shall I install the new 32a mcb in the main board on the RCD side or main switch side?
Thanks

With regards to the Emma Shaw case:
The installation was constructed to the 16th edition.
She was electrocuted in 2007.
The ECA were called as expert witness.
A screw fixing plasterboard to metal stud work penetrated a cable, making contact with both the Line and CPC.
Subsequent energisation did cause part of the damaged CPC to be vaporised, which left the unearthed metal stud work live.
The CPS decided there was insufficient evidence to prosecute anyone for manslaughter.
The Coroner did not write to every NICEIC QS, he wrote to the NICEIC and the Chair of the Competent Persons Forum.
Two people, an unqualified Inspector and his QS were prosecuted under HASAWA section 7.
The QS was found guilty and fined £1000.

how the hell does the CPC "vaporise" when the circuit was energised?? If there was a dead short between L-E then the OCPD would have tripped. Sounds a bit iffy to me.

I read something ages ago, but can’t seem to find it anymore....That the circuit breaker had been reset many times effectively blowing the line to earth fault clear.

That is pretty much correct spin.
Under rule 43, the coroner wrote to theNICEIC, and they wrote to all their QS's & PDH's at that point in time.
Or at least they told the Coroner they did, because if they hadn't the Coroners powers could have taken that further.

You shouldn’t export a DNO earth without their consent. What you do is provide your own! That’s called TT and doing the RIGHT thing. Get over yourself.

What about extending the equipotential zone?

Have you ever considered actually backing up anything you say with a Regulation or a quote from somewhere?
Citing publications and Regulations that do not agree, or in fact actually disagree with your statements is not sufficient.

 

[bigbob1]

your ****ing in the wind bob.
All them school jobs I’ve done where different buildings exist from the same installation, all the new build student block accommodations I’ve been involved with and army base new builds ,all with the installation earth extended to each building and non TT.
All the jobs I’ve been on and tested etc, don’t recall many being TT where numerous buildings exist but all must be breaking your law then?

With designers getting permission to run submains you can p*** in the wind all day long.......because they have a defence. It’s a phone call and an email we do it all the time, it takes 15mins.
And yes they do say no a fair bit.

Read up ^^^ Mr IET forum member.

Officially out.

I take it that’s a no.
I am no longer a member of the forum, and have not been so for some time.
What I find odd, is that I can find Regulations in both ESQCR and the old Electricity Supply Regulations which state the DNOs cannot refuse a connection for an installation which complies with the Wiring Regulations.
I can find publications from The IET and Stroma describing how to export the installation earth to outbuildings.
There is even a video by John Ward detailing how to export the earth.
That’s without really trying.

You on the other hand are unable to find anything at all to back your claims.

Why is this?

Read up what exactly????????????????? The fictitious regulation you won't tell us about????????????????????

Yep totally acceptable. Let me guess hdpe pipe? Metal shed extend it.
Use the armour as the cpc....oh no you have to use armour glands ahh a 4 core SWA? Baring in mind that’ll cost more than an earth rod honest to god comedy gold.

They can refuse to provide an earth connection.

ESQCR section 8 first paragraph.
But it’s okay for you to use their earth?! It’s not a bad thing because when their neutral goes and someone dies they just go ‘he didn’t have permission from us’!!! I can show you a whole estate that was section 24’d because of supplies to garages done by a part P wonder. You are either a really sh*t troll or you genuinely think what you proclaim, which is worrying.

Is this still going ?? Sorry I've been away from here since last night, doing a shed supply,TNCS earthing.

Thank you for a deeper insight in to how wrecked the system really is in this country. The ‘minimalistic’ approach taken.
