How do you know that the supply does or does not comply with the ESQCR?
Where does the date 2013 come from?
If you say a SP/RCBO can't be used, where does this leave the likes of S/P MCBs?

Are we talking about SP MCB's and RCBO's protecting final circuits?

If so then we don't deal with PEN conductors as per your reference of 537.1.2

Have you finally bought a copy of BS7671:2008?

"How do you know that the supply does or does not comply with the ESQCR?"

I rang edf this morning and said they would ring me back - still waiting.

"Where does the date 2013 come from?"

Where abouts in that document?

 

[GaryMo]

No matches in the above document for '2013'

I still can't find it, where does 2013 comes from??

 

[GaryMo]

In what way doesn't a TN-S or a TN-C-S supply comply with ESQCR 2002?

I can only see this directly relating to the supply:

"Pre-1937 cut-outs with fuses in earth or neutral conductors must be removed from service by 2013."

It's very rare to find cutouts like this now, though I personally requested one to be changed around 6 months ago. First and only fused neutral I've come across, 30A carriers IIRC.

Yeah, you don't need to switch the neutral if the supply complies with the ESQCR with the exception of the main switch for a domestic etc.

Surely if the supply doesn't comply with the ESQCR then you'd just ring the DNO and ask them to sort it, instead of redesigning your installation to suit.

That's what I did when I came across a fused neutral
It was replaced with a new cutout within a couple of days.
