-------sne type cut-outs installed in blocks of flats have led to confusion
over earthing systems.

it is possible to find SNE (separate neutral and earth) cut-outs installed
by other parties in blocks of flats that are fed from the distribution PME
point of supply. the link (neutral and earth) must not be closed in a SNE
cut-out.

UKPN are a DNO and their work must comply with the ESQCR regs
and their responsiblity ends at the intake position.
the BNO is then responsible for the rising mains and cut outs/red links.
all BNO work must come under the current version of BS7671 and
a combined N+E is not allowed.

Regards.

is your consultant giving dodgy advice-like you dont have to main bond
services anymore?
well---who do you trust!

I've been sent a rather large document by the ECA which details UKPN's earthing arrangements going forward.

It seems like sensible guidance from what I've digested so far.

Are you on a journey of rediscovery UKPN



LoL - now did I say that ? - wasn't it actually regarding bonding a plastic water main - do try and keep up, there's a good fellow

Oh dear!!!!!

According to my information the BNO work must becarried out in a safe and competent manner to a level complying with or exceeding the requirements of health & safety and electricity related legislation and, in particular, relevant requirements of the Electricity Act 1989 (as amended), the Utilities Act 2000, Electricity At Work Regulations 1989 (as amended) and the Electricity Safety, Quality and Continuity of Supply Regulations 2002, from a legal standpoint BS 7671 only applies from the seal postion are you getting this mixed up with the installation they connect to must be compliant to BS7671.

I've sent lots of posts on the water bond post.

Your saying it should be bonded, others say no.

Have a read of mine and give your opinion, with some reasoning if possible

Hurry up though because I've scrapped most of my 10mm green yellow and am about to throw the lot out tomorrow!

Does that mean the DNOs have given up running CNEs to each flat (i.e. using the gas pipes as parallel N conductors) at long last?

Perhaps best to keep just a bit, Leckie - you never know when it just might be extraneous -

No , sorry it's too late now. Henceforth if I see any clamps on a water pipe with a plastic incomer I'm going to give it a code1!

I'm going to re-read gn8 this weekend just to make sure though. I've got the old gn8. Is he new one a big improvement?

LoL - don't you trust me

Steady on the Code 1 though - what regulation does it contravene ?

I've not read the new published verison to be honest - a version I did see wasn't significantly different

It contravenes oms law

tomorrow-like every day since the mid-sixtys electricians
all over our land will accept the advice of their DNO/Meter op
and bond to their requirements.
I enjoy these topics but I cannot quote non-statutory books
to my customers. the wiring regs are not an act of parliament
and the guides are generally helpful but to hear posters saying
the words like "rules" is a step too far.

tomorrow all over this land our customers electricians will
bond main services regardless of if they are plastic origin.

millions of them have followed this advice and will continue into
the future.

and we have only been discussing water/gas, there are many
more.

I have NEVER had a contractor dispute my earthing advice
and talking about "more than 22k" and "low risk" "how many shocks have there been anyway" is rediculous.

UKPN will look after you!

Regards.

You heard it here first folks - Sweet 'n Sour Light and Power - the guys who told you to bond plastic pipes -

I spent enough time in the past with you lot, DNO's, what about that clause in the agreement between the customer and the appropriate electricity board which states, please note that our employees and contractors are not qualified to advise on electrical installation matters, and then it goes on to say you need to contact a qualified electrician to inspect the installation and advise on earthing and bonding, or did you get mixed up about that one as well.

"i enjoy these topics but I cannot quote non-statutory books".

No doubt that is your personal preference UKPN but the current UKPN Earthing Manual does quote from BS7671.
