Thanks, I suspected that there would be issues. I think I'll see what JCL recommend themselves. Of course I might just be falling into the trap of wanting a feature just because it's there. My reason for thinking about flourescents is to use them for their efficiency, which really counts when on...

I'm researching some new lighting for my house. So far it looks like the JCL FlexiDim or the Hamilton Litestat Digital Mercury systems are most suitable. Does anyone have any experience with these? It looks like I'll end up with lots of low power halogen bulbs for the effect I want. Having...

I know there are some good posts on here, and when I get the time I'll search, however maybe some of you can give me a shortcut with some links? (external or internal, I don't mind). I plan to completely revise the lighting in my house. I had been thinking about going for one of those...

Take a look at additional note b to table 1 in part P. This will not be adding "new" cables, it will be replacing existing cables which are dangerous.

chapeau, read Approved document P additional note d to table 1. Zoning does not come into it. If its "adding" work in a room containing a bath or shower then it is notifiable. NitroNick - if you want to run a 1.5/1.0mm2 lighting cable off the 2.5/1.5mm2 ring then you'll need an FCU to protect...

OK, I'll have a go. I don't have any books with me so this is from memory. 1) If you want to reposition the hob without completely rewiring, then yes you need to insert a junction and a suitable switch will suffice. Check the regs on max cable length (is it 30m?). Have you already checked...

Reminds me of one of those wildlife TV shows where a pack of hyenas are ripping apart some poor defenceless animal. What did you all do before t'internet? Go and find some young apprentice to ridicule? :roll:

Assuming the ring uses 2.5/1.5 twin and earth, not only is the 0.2 ohm difference a problem, but also the ratio to cpc resistance is a problem too. I'd suggest that you map all points and estimate the total cable run length and this will give you an idea if the cpc resistance is high or the...

What do you mean by "I changed the light switches over"? You swapped them or put in new ones? Also what do you mean by "red, black and neutral ones"? Do you really mean red, black and yellow? Unless it is obvious (e.g. you have changed changeover switches to single-throw switches), then...

Even if the work is not notifiable, there are various health and safety regulations that apply. Your expression "nearly blown himself up" suggests that either he was working on a live circuit or maybe he wired it wrongly, both of which imply that he was not competent to do the work.

Thanks for letting me know - I didn't think to check! However as Adam points out, the removal of P2 doesn't remove the fact that BS7671 requires said documentation at or near the DB. I have several friends who have bought houses which were built after the introduction of part P, and none of...

So I should connect the cpc of the lighting circuit which is common to both bathrooms to the supplementary bonding in the airing cupboard?

I am currently creating an extensive document about my own domestic installation as a permanent record of all the work I do on it (so it will include all my detailed inspection comments, test results, copy of the PIR etc). I'm doing this for my own benefit, because it is good engineering...

My supplementary bonding appears to be only in the airing cupboard which is close to the two bathrooms so I understand that it is acceptable. However I was surprised to see that there is only bonding between all the pipes and not to the electrical earth which is present in the cupboard (via the...

Yes, 2.5/1.5 T&E. Thanks for the info (just shows how much of my theory I have forgotten). My rough estimate of the cable run is about 60m. I guess with the higher nF/m of 2.5mm2 cable, plus the inductive effects, the currents I measured seem plausible. I still can't find a cpc short...

I realise this may be a fairly obscure question for the forum but here goes anyway. I am just coming to the end of carrying out a full periodic inspection and test on my house electrics. During testing I found a few hidden faults (including one ring incorrectly wired "through" an FCU!), one...

OK, I know it's a cheap system but I don't want to replace it until I have my extension done, so I have to live with it for a while. Basically the problem occurs after a power cut (which unfortunately seems not uncommon where I live). The battery takes over OK, but the alarm goes into a...

I'm in exactly the same position as you, but have a different opinion. I am fully in support of part P, I am just annoyed that as far as I am aware, the Government still has not introduced the competent person scheme for DIYers. The last time I looked there were still just the 5 bodies that are...

Thanks for the replies. What's wrong with halogens?

I moved into my current house about 6 months ago. When I arrived and met my neighbours, they all told me that we'd have to increase our lightbulb budget because they don't last long around here. No-one gave a reason why so I thought they were trying to wind me up. Well after 6 months it is...
