I got it at last today - the big red book and I will be studying it rigorously over the next few days.Watch this space folks.....................................

I see that the 30mA protection on all socket outlets only relates to general use sockets.You can still have sockets for specific equipment not on RCD if they are labelled for said equipment or if they are used by trained/instructed persons (not exact wording, but you get the idea)
Not quite......
Not as simple as saying "these sockets are for that".
I have several discrepancies I have taken up with the IET, but only one reply so far. And what I have pointed out to them, they inform me, has already been pointed out to them by the NIC.

Is that still the case if cables are buried at a depth less than 50mm and not protected by an earthed metallic conduit or similar>
Regard the 50mm depth issue and 30mA protection......
Tails are going to cause a problem.
I can also see FP400 becoming a more popular choice for supplies to fire alarms.

Sorry, yeah, I was looking at it from my point of view (industrial installations) where the cables are not buried.
That's how I read it though, Lec.I will have another look on Monday just to check, but I'm sure I interpreted it correct
Been thinking about the buried cable malarkey.
1) Lets decide that all sockets should be RCD'd anyway.
2) Wall lights will be a fiddle, but switch drops could easily be done in metal conduit. No need to go to a full conduit system, and no need to use the conduit as cpc, just bush it into the flush box and run a flylead to that.
3) Find a route from CU to ground/first ceiling/floor void, and one from there to the loft where you can box in galvanised trunking.
Yes there will still be some problems to overcome, e.g. cooker circuits, but 90% (?) will have gone away with the above.
And here's a radical thought: just what is going to happen if you continue working to BS7671:2001, and continue issuing certificates to say that your work complies with BS7671:2001?

Think of that from the correct perspective:
That is, supplementary bonding is required, unless the three provisions of 701.41.2 are met.
And it is not an either/or situation because 701.411.3.3 requires RCD protection for all circuits in the location whatever the state of bonding.
Just thinking of a situation where someone asks for new lights & an ext fan in the bathroom & you got to RCD it
That's where a RCD FCU comes in.
If you intercept the loop in feed to the bathroom then the switch feed and return will be protected by the RCD.
This is for a very good reason.
Imagine you go into Mrs Bloggs house to install a shower in her bathroom. Everything is supplementary bonded, and you RCD Protect your shower.........are you going to RCD Protect everything else too? Nope. So the supp bonding allows compliance for a 17th edition circuit in a 16th edition bathroom.
