Short, pithy and to the point. Like it :D

I agree with Spark123. The locking system is not designed to resist tampering, it is designed to stop the inadvertent re-energising of the circuit whilst work is in progress. If someone is going to stand there with a small screwdriver circumventing the lock they are deliberately trying to...

They are also allowed to be powered from a "local regularly-used lighting circuit". IMHO a better idea for a domestic situation as it stops the breaker being tripped to stop nuisance alarms. The local regularly used part is so that a power failure will be quickly diagnosed because the lights...

Definitely notifiable. There is legal precedent that states that any regulation which is intended to be restrictive must be read in a restrictive manner. Part P is intended to restrict the amount of work done outside of it's notification requirements so, if there is a semantic debate it must...

There'll be a moderator on soon telling you that there's a rule about asking about prices for jobs!! :) But, if the wiring looks Victorian, as do some of the Sparks round here, then you may well need more than just a new CU. It is notifiable and, unless you use a self certifying...

Your old switch consists of 2 sets of terminals, arranged in a triangle, 'a' has its popint to the top and 'b' has its point to the bottom. Your new switch is the same, but with both triangles pointing up. So, connect the red from the old top middle 'b way' to the new right hand com and...

Personally, I don't think there's much to choose between the 2. However, changing a CU is not just a case of whipping one out and coneecting the other in its place. In this post http://www.diynot.com/forums/viewtopic.php?t=71544&highlight= And that's just the things that you could...

Do not insert a 40 Amp fuse into the existing circuit. This much power has to be handled with extreme care. To change the 30 Amp fuse to a 40 Amp fuse could be dangerous and could lead to an electrical fire. Also, certain CU's will only accommodate a fuse of a max rating of 30Amps. If you...

Or none of the above? An 8kW shower would draw about 34Amps so why do you think it is one of these 3 fuses? If it is, the answer could be in the question, it doesn't work because the fuse has blown. Who is to fit this shower and are they aware of the need for supplementary earth bonding?

"Qualified as what, if he couldn't find that fault?" I ask myself...

Much depends on what is there already. A cooker circuit will have been installed with at least a 6mm cable and on a 40A + fuse/cb (normally, though yours could be different!). If it's a 10mm cable it may take some arranging to get into socket terminals and I would like to see the fuse/cb...

How many lighting CB's/fuses do you have in your CU?

Gordon Bennett! That grey sleeved jobber is, from your description, the live feed to that part of the lighting radial that serves the hall. It sounds like your system has witnessed a level of expansion since it was installed. The system you describe sounds about 40+ years old as I take it...

Can you elaborate on what light fitting you are talking about with the 3 cables. How old do you reckon your electrical system is? How are your lights connected, is it by choc blocks, say, or crimps or what?

I wish I'd thought of that. Good solution.

To daisy chain the spur off an FCU would do it. I think the answer here though will be determined more by what is physically possible.

I'm not sure I can believe this to be a serious question. 8.5 kw is equivalent to a current draw of about 36 Amps, so needs to be on its own RCD protected circuit fed by at least a 6mm cable with a 40Amp MCB a double pole switch and supplementarily bonded throughout the bathroom. It's a...

Please please please tell me you're having a laugh, please..

Once the plagues of locusts and rats have finished with you, what is left probably will - you may hear a gnashing of teeth about then too.. Worse, if there's a fire , say, and the insurance company detect uncertifed work, the second bang will be the insurance cover going.

Yes you have sinned by carrying out notifiable work without using a self crtifying spark or informing Building Control.
