Whew - a lot to digest in one page!
How about splitting it into sections, maybe
- general layout of installation (CU, rings, radials, outside feed etc)
- power - how many sockets to install etc
- lighting - choice of types etc

Will think about that one later.
Have changed the outdoor MICC sentence, as all outdoor cables are prone to failure from water ingress, the difference with MICC is its hygroscopic, ie will suck water vapour in out of the air if it gets the chance. NT 15:47, 4 January 2007 (GMT)
Categorising sounds like good formatting in principle, but what when something falls into 2 or more categories? NT 08:48, 5 January 2007 (GMT)
I know, that's bound to crop up. I guess you just put it in one and have a link from another. --John Stumbles 13:22, 5 January 2007 (GMT)
Or perhaps have another section (eg 'misc') for pieces that are relevant to more than one category, and a link from each of those cats to misc. NT 06:56, 6 January 2007 (GMT)
Why the didactic "dimmed PIR lights are a gross waste" statement. This is surely opinion ?
Dimmed PIR lights: May I suggest we discuss it on uk.d-i-y, because then what we say will be subject to input, correction, etc from other regulars. There is a good reason why I removed them from the recommended area, but would rather others had the opportunity to correct if I'm wrong etc. Always better if this article represent considered input of many members instead of just us two. 18.104.22.168 15:39, 9 January 2007 (GMT)
Having read this informative text for the average DIYer, I myself found points to consider although I'm a Part P registered electrician! However, I am dismayed that the only disclaimer mentioned a "skilled electrician"! There should be refence throughout, and at the beginning of, these pages to the fact that most of the work discussed can only be undertaken by a registered person.
The fact that that isnt the case may explain why its not mentioned - DIY is still legal!
Circuit design instructions
"Care should be taken to ensure the circuit is tested and figures compared with those in the current edition of BS7671 for maximum Zs."
True, but I dont see how it fits into this article. We could write a book on all that, this article is more for tips that make the rewire better than the usual by avoiding common issues and pitfalls. NT 23:10, 3 April 2007 (BST)
Low Voltage Wiring
I don't think that burglar alarm cable is suitable for phone use as it's not twisted pair this could also affect other applications mwarby 18:07 7 May 2007
Telephone bandwidth is 4kHz which is never going to radiate rf, and phone wires have been untwisted for most of the 20th century. NT 18:56, 7 May 2007 (BST)
One has to assume that 21st century telephone bandwidth is something like 1.5MHz when ADSL is present on the line. Lack of a twisted pair will affect sustainable data rates.

TT installs / RCDs
This seems a bit confused:
"TT: a type of earthing that uses a local earth rod. TT installations must include a "Whole House RCD", since an earth rod alone is inadequate to clear faults. Whole house RCDs should be avoided with other installation types, as they're a known source of problems."
This seems to be conflating two issues: "Whole House RCDs" are certainly deprecated for various reasons, but the phrase referees to the practice of using a single 30mA trip threshold device to protect the whole CU. This is different from having a 100 or 300mA trip, time delayed RCD protecting a split load CU with downstream 30mA one for appropriate circuits only. Unwanted trips of the top RCD are very rare.
I would suggest separating the two sentences, since they are both correct n the right context, but don't belong to each other.

I'm inclined to think the way forward is more to simplify the writing here, and maybe get into more depth in the RCD article. This article is already a big enough chunk to read imho. NT 15:17, 5 February 2008 (GMT)
