If I had to make a guess from your description..... http://www.theiet.org/Forums/forum/messageview.cfm?catid=205&threadid=10468 http://www.diynot.com/forums/viewtopic.php?t=33923 http://www.diynot.com/forums/viewtopic.php?t=28804

I disagree. The last thing I'd advise anyone to do is cut the plug off a new appliance and connect it into a fused spur before buryng the flex behind tiling or plaster. What happens if it goes wrong and the appliance needs to be returned after you've butchered the cable? There's also a good...

But you'll also need to find the other end of the cable and make sure that the earths are not cut off there as well, and also check continuity back to the earth terminal in your consumer unit...

Guess the question? :D

And don't forgot to check for pipes and cables before whacking a screw through the floorboards (yes, I am speaking from experience here :roll: )

Could it be a bell transformer for your doorbell? it's feasible that this is fed from a ground floor lighting circuit if the bellbox is mounted near the ceiling in your hallway. Try removing the fuse and see if the doorbell still rings...

Busbar diversity - hmmm, tough one :) It's a problem I struggle with daily, and there's really no hard and fast rule. One of the main factors to consider is what sort of a shift pattern the factory runs. If it's a bell to bell operation like ours, then 30 seconds after the start of shift /...

I'd probably go for a MEM Glasgow switchfuse. The catalogue is available on-line but is about 10MB so I won't link direct to the pdf file. It's about halfway down this page though: http://www.memonline.com/publications/ As for the DB, normally I'd go with a MEM Memshield 2 board (details...

It was all going quite well until I read the last sentence. There may have been 40,000 house fires in England alone, but how many of them are down to cigarettes, candles, faulty appliances, chip pans etc rather than degraded fixed wiring? Sounds suspiciously like the misleading statistics...

Or run the cables in galvanised steel trunking with 20mm steel conduit drops to the sockets. That's how we'd always install this type of thing in our factory. Slightly more work installing the containment (not much though) but gives a very neat job and makes it dead easy to modify the circuits...

But surely the "main isolating switch" for "operation by an electrically unskilled person" would be the main switch (presumably labelled as such) on the consumer unit inside the house, and not the isolator outside the property?

If you go to the IEE wiring regulations forums (http://www.theiet.org/Forums/forum/) and search for "green goo", all should become clear.....

Why do I feel as though I've just entered the twilight zone? :shock: :D

Why was it disconnected from the mains in the first place, and what reasons do people give for describing it as dangerous? Just because the installation is no longer mains fed doesn't necessarily mean that the danger has been eliminated...

One make of fan (IIRC its Xpelair, although it could be Vent-Axia) have a micro switch inside which can toggle it between input and extract. Are you sure there's nothing like this?

Last time I did it I used my SDS drill on hammer stop with one of these: http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=101988&ts=37603&id=16724 Works quite well as long as the blocks are fairly soft, but I imagine it would blunt and chip fairly soon on dense block or brick. This one...

http://www.bathnes.gov.uk/BathNES/media/press+releases/2006/Council/Building+control+prosecution.htm I agree it is not the purpose of this forum to spout part P to every post. However for people to make an informed decision on whether to ignore it or not, they need to be aware of it's...

Or are you referring to a computer room type setup, where load shedding is used to maximise the time a UPS will hold up critical equipment, or to reduce the demand on a UPS/Generator setup?

It doesn't matter whether or not it will "do any harm". Part P is the law, like it or not. Anyway, as the last post was a week ago the job is probably done by now. :wink:

The last ones I bought came from Maplins, although I'm pretty sure that I've seen them in B&Q as well. Failing that, any TV or satellite shop should be able to sort you out.
