Ouch. That must have been hard work!

"I am not qualified, so the following is only an idea which may be a complete death trap. Unless you know you are suitably qualified, consult someone who is, e.g. an electrician." It sounds like this bit is done using conduit wiring using singles. I presume there is an earth connection at the...

Imagine you have a kitchen wired using singles in conduit, with accessories in metal boxes. Boxes and conduit are sunk into the wall. We could have two socket outlets on a horizontal level with, and either side of, a cooker isolator. So we have: socket outlet cooker isolator socket...

Thank-you for coming back on that one. Did you mean that flexible conduit is a nightmare, or any conduit?

Just seen some flexible polypropylene conduit on Toolstation (sorry): http://www.toolstation.com/shop/Electrical/ConduitandTrunking/d190/sd2743 I was wondering if this stuff could be used as the conduit for conduit wiring using 6491X singles? In particular I was thinking not just a...

Me and a couple of guys are doing various domestic wirings and stuff. We are tending to use MK Logic Plus accessories for the mains wiring. So we come to wanting to put in structured cable with Cat5 cable. We are then wanting to terminate the structured cabling with accessories which match...

Maplin does black sheathed 3 pair telephone cable good for wiring telephone extensions round the outside - have done so for years. You'll also be wanting black 5mm cable clips. You can get white ones anywhere but they look really naff holding up black cable outside; black is much better, but...

Have you tried an SDS drill? I've heard it called "Paramount board". No problem, just prise the cardboard out, with a pair of pliers/screwdriver/whatever, in and around the hole until you have sufficient space to put in a dry lining box.

Degree Sign ° ALT+0176 (not to be confused with the Masculine Ordinal Indicator º ALT+0186) So we have: 0°C = 32°F = 273.15 K Try not to run your cables at 45° Other useful ones: Plus-Minus ± ALT+0177 Micro Sign µ ALT+0181 Multiplication × ALT+0215 Division ÷ ALT+0247

How to get various useful symbols on a standard Wintel PC running Windows assuming ISO-8859-1 land: Squared ² ALT+0178 Cubed ³ ALT+0179 Quarter ¼ ALT+0188 Half ½ ALT+0189 Three-quarters ¾ ALT+0190 I think I've managed to get Squared and a Half down pat. Various others I get using...

Cables are normally identified by the cross-sectional area of the conductor, measured in mm² (not mm). (For Twin & Earth cable, the dimension is the CSA of each of the live and neutral conductors; the earth conductor often has a smaller CSA.) If you do mean 10mm² conductor cross-sectional...

The Burghfield Aqua Sports Club is basically about waterskiing and wakeboarding which take place on an (outdoor) lake :-)

I've seen an installation with separate Henley blocks for the live and neutral, at the Burghfield Aqua Sports Club club house. In that installation the tails are of the type where the outer sheath is coloured (red/black) throughout its entire length. One wonders whether there would ever be...

Yes both the live and neutral have the outer stripped back by what looks like over an inch. He could fix those though because they are downstream of the isolator. Oh except that some funny guy put in a 2 pole isolator and then only used one pole, so the neutral isn't isolatable. But...

I can imagine that putting a CU in a loft would be almost impossible to fit in with all the relevant rules. In any case, starting an inspection in a loft isn't going to put the inspecting person in a good mood :-)

Thank-you for the replies. It was most helpful to have it nailed down to various concrete issues. Accessibility for potential future occupants would very much seem to apply here. The best access to the loft would be a dedicated ladder (i.e. a folding ladder attached near the loft hatch)...

I can imagine the eyes rolling up already :-) Small single storey house (but detached, and on a fair sized plot, and in a reasonably good location, hence reason for purchase). No convenient place to put the CU in the main part of the house, but there is a plenty big loft, which is where most...

Er, yes, that's the dull and obvious part on the right. I was asking about the bizarre stuff on the left. Compare it with page 2 of this: http://www.underfloorheatingsystems.co.uk/pdf/control_pack_instructions.pdf With the Contintental one, if the floor is cold and it starts running...

Have a look at page 2 of this document: http://www.alderkey.co.uk/literature/Continental%20UFH%20Ltd%20-%20Construction%20Guide%20r200103.pdf It's a picture of a "Continental" underfloor heating manifold. But I can't figure out how it is supposed to work. I thought that underfloor...

Good point. I'll think about it some more.
