if he's accessing from below however, the insulation may fall out. he'd have to make sure the cables are going to rest above the insulation and not get surrounded by it. finally the lights themselves may cause a problem with the heat generated.

the title could be listed along the lines 'urgent - part p. read before doing electrical work' i think this would get everyone's attention when they visit. i don't know whether the word 'scams' could cause legal problems for the site, but if this is a concern it could then be replaced with...

ahh yes, although not that common, some flats are separated by insulation/soundproofing material. have a quick check on this first, because it will make it almost impossible to put all the cables above your ceiling. this may also stop you from putting the downlighters in (heat build up)

we have to first check for diversity. what exactly are the other ways on the CU?? ie what amp ratings are they and more importantly what do they supply?? also 6mm isn't going to be big enough. where is the cable going to be routed (ie through floorboards, insulation, etc...), and how long is...

unfortunately nabby68, you're in a difficult position and it will require some messy messy work. you have 3 options: 1) ask the guy upstairs if they'll let you get access. it's not an unreasonable request, and would only take a day. then route cables as normal practice and drill through...

seems good as is. as short as can be without losing detail and precision..

i suppose there's a danger in an inexperienced diy-er reading this post and jumping to the conclusion 1.5mm is ok in all cases. cos it isn't. however at the same time it would be incorrect for people to say it's dangerous in all cases. such statements should be corrected. i don't think such...

hi spark123 as i said above, as long as the installer is competent and has assessed the circuit, then it is no less safer. would you agree with me on this statement?? i never proposed fusing downstream all the time, just where it may be more practical to do so, as it wouldn't be any less...

kevplumb - i don't understand your post. you used to build what things and what went wrong?? and who's asking for what advice and not listening to it?? "...click here" suggests that i personally contributed to that particular clip. so your post comes across as a joke. im here in this forum...

im not 100%, but pretty sure that everything's to standard. british gas are obviously corgi registered, and as far as im aware, corgi members are allowed to do electrical work related to any other work they are doing ie adding spur when fitting boiler. have been searching for more...

you can only say it's dangerous if you can prove/argue why. and you haven't exactly been able to make any valid arguments against my points!

haha very funny breezer! :D yes but an underground cable doesn't have short circuit protection. if one cut through it, this would be extremely dangerous. an internal cable has short circuit protection, and the installer can ensure that disconnection times can be met without any damage to...

i don't think you'll be able to get type C breakers for such an old board now. either replace the consumer unit and fit a type C, or im afraid they'll have to put up with it. if the bulbs are blowing regularly, make sure 240v bulbs are being used instead of 230v. this will result in the...

no breezer, i have to disagree with you here. i don't see how this would cause an accident. as long as the cable is fused along its length, it is being protected. it won't carry any more current than it is designed for - the current has to go through the fuse. therefore there is no risk of...

as plugwash says, this could occur with any cable anywhere. the cable fused downstream is no more dangerous than any other cable in the house.

the short circuit would trip the MCB almost instantly. whoever sliced into it would know immediately, and would (i hope) get it fixed.

i asked this in another topic as i was unsure about a fuse downstream: http://www.diynot.com/forums/viewtopic.php?t=26997 i would think its perfectly safe for a 1.5 connected to the cooker circuit providing it was fused downstream (overload protection), and providing disconnection times were...

considering you are here asking for help, it may be in your favour not to behave in such a rude demeanor. part p wouldn't affect this job. besides, even if it did, so what? help 'em out if you can, contribute to the forums, continue to joke and mess around. then let the recipient decide...

no earth rod req'd. dont forget the circuit must be RCD protected. so either an RCBO or split-load.

16A CB is fine. i would personally only ever use SWA outdoors (safety). get 3core 2.5mm2 SWA. this will easily take the current you want to use, and satisfy volt drop. it's about 1.5cm diameter.
