No problem with modern CU's on wood,they are fully enclosed....only issue might be with old 3036 CU's with open backs....Building regs height is same as switches,1.2m to the top of CU and readily accessible,which rules out cupboards etc..but that only applies to new build.
Hi tuf I score round the sheath with a stanley....bend it back and forth a few times and the sheath will break,and can be pulled off...the inner sheath is soft and can be easily stripped.

 

[i=p/u]

just check me regs your saying wire puller

 

[i=p/u]

cheers..., the 4 way cu im mouting has no 20mm knock outs, it says mini trunking, but i can run conduit into mintrunking slot , which shouldnt be noticeable to much....

i thought the recommended mounting height was min.1200mm and max. 1500mm, for CUs. stand to be corrected though.

 

[i=p/u]

on new builds apparently, i also plan to mout sockets at on 150mm off floor, cause its not a new build and there higher than the previous ones

 

[telectrix]

150mm from floor level is a bit low. skirting board is usually close to that height

 

[i=p/u]

well because its surface mounted i thought, sit nicely on top... maybe il change too 450mm. i havent priced this job yet the materials in total came to £350 does the cost of materials play part in your price

 

[i=p/u]

dont worry he'l pay

 

[telectrix]

well, of course the cost of materials plays a part. estimate the time it will take, multiply the hours by what you want to earn per hour, add materials, then add 20% to the total.

 

[i=p/u]

wwould you charge them for pricing around or is that my lerning expierience

 

[telectrix]

not sure what you mean. add up your materials inc.vat.£350. say its going to take you 12 hours at £20/hour, thats £240. added that comes to £590. add 20% gives you £708, round off to £700 total ( add vat to labour if you are vat registered. sssimples.

cheers , off a go to play with me tools, arnt shiny no more and scattered all over the place....... bit of head scratching

An interesting discussion document on all this:

[/URL]Arguments I've heard against CUs at this height (1200mm) for a couple of reasons; aesthetics being one and easy access by little fingers (kids)! Not so much of an issue if it's in a cupboard at this height but then there's arguments about that i.e. accessibility. Its a great height IMO to work on, pull up a chair and get on with it! No standing on your feet. A great "leveller" for us of different heights ourselves. My home one is in a porch butt up against the ceiling - horrible to work on. The new one will be at 1200mm (chair height) but again in the porch - unlikely that little kids will be in there unsupervised. Then with a modern CU I would say the chances of a child taking a screwdriver to the CU are remote?

The whole Part M thing is emotive. Say your user is confined to a wheelchair and something trips in the CU. They access it nice and easy (at 1200mm) and reset it. It trips again and it turns out its say a rat chewed cable in the loft - no way are they getting up there. The washing machine element ditto. Comes down to a bulb going on a ceiling fitting - they're not getting up there are they unless they've got a Genie! What next, all lights on walls, no higher than 1200mm to comply with Part M?

it's a load of bureau cratic garbage thought up by pen pushers with nothing else to do with their time. best solution is to confiscate their computers and replace them with playstations. then they'll have something to occupy themselves with, leaving us free to get on with the job.
