outkastchris

yes another one and I have a few questions

GENERAL BACKGROUND INFO
1st time buyer,
Not alot of money left I believe most people say that once you get a house and a wife, don't quite know which is more expensive yet,
heating engineer, CH system wiring and basic electrical knowhow
dad as back up / cheap help, retired with load of trade knowledge but very dated

HOUSE
electrics need updating 1 double in each room old black rubber wiring I know its got to come out
heating needs updating ripping out downstair suspended wood floor putting in wet underfloor heating
upstairs internal walls need removing due to previous alterations issue will loading on existing structure plasterboard stud wall going in


I will be getting in the sparky to complete the install and get it certified! altought dad says he could do it but he cant register it and he keeps mentioning hes not up to todays standards so as for those key details I won't let him near the electrics and seeing some of the oldschool ways he works sometimes I do get worried sometimes but I've never seem other tradesmen In site conditions.

PLAN OF WORKS
rip out upstairs walls
rip out existing electrics
fit the new stud walls
fit plumbing / upstairs heating circuit( DIY)
install conduit to upstairs / downstairs cut in back boxes (DIY)
install conduit for data cables CAT5 / 6 (future proofing) TV cables telephone alarm wiring ( DIY)
I KNOW ELECTRIC AND DATA CABLES HAVE TO BE SEPERATE!
get plastering done all walls and celilings skimmed
rip out wooden floor get floor prepaired
install last bit of conduit under floor for the downstairs circuit
get (PRO) sparky in pull wire to locations, fit and move CU, test and cert
hope to move in before xmax only 5 months to go

CIRCUIT DESIGN
lights 1 upstairs 1 downstairs
sockets
1 X lounge dining and hall 2G x 13
1 X 2 bedrooms and landing 2G x 9
1 X 3rd bedroom come computer room / study 2G x 6
1 X kitchen sockets 2G x 8

1 X immersion
1 X boiler and underfloors heating controls
1 X loft 2G x 2

QUESTIONS
1 lighting circuits should 20mm round / 16mm oval conduit be ok?
2 Ring mains what size conduit should be suitable for the types of circuit I have listed
3 Distance between CU and water pipes? I'll probably have the pies boxed in
4 Distance between electric and data cables eg CAT5 / 6 in and out of conduit?
5 Do I have to fit my sockets to the new rules 450mm
off floor dont really like the idea of having sockets half way up wall I understand the reasons behind the rules?
6 conduit colours Im thinking of using the black one for the 240V electrics and the white for the other utilitys can I wrap coloured tape or mark them regularly so i can identifiy them at a later date should I ever have to knock into walls Im guessing to cant mark them with colours that may cause confusion with electrics

WHEN IS THIS WIRELESS ELECTRIC COMMING ALONG!!!

Youll want more than 1 socket in longe i would say at one in each corner. plus 4 where you keep the tv. Same with bedrooms living in house with only the master bedroom with 4 sockets. Even with the second room is only a wee bit smaller is dam annoying.

While they recommend that data cables and main cables are kept apart there no particular distance recommendations and plenty of installs have then next to each other. A few centermeters will do.

Best thing to do would be to draw a plan of each floor in your house on some good old graph paper and plan where the bed will go. Where the Tv the Hi, fish tank etc will go. How many sockets you think each would need.

I know a bit of networking stuff but not a sparki I believe that you can have the sockets at what ever height you like the 450mm is an recommendation as long as the sparkie can prove there is reason for the difference in height and diagonal cabling runs as a result.
Bed side lamps. Pc for the kids when there older. Lamps above beds.

You can download a free copy of the part P document one here http://www.theiet.org/ if you can find. It will give you some idea of whats required.
