Not sure those two words can be used in the same sentence in this case :lol: Thanks for the replies, particularly Adam showing his extensive knowledge as always :D I have to say I've learnt more on this job than on any number of courses or book reading. I will save the other...

MA, Nothing wrong with asking questions if you are unsure in my opinion. I've corrected your image link Couple of things I can hopefully clear up... The picture and your description shows that you have a RCD (RCCD) main switch rather than a RCBO. The Rail the breakers...

Found this one today: The pic isn't great but the installer earthed the swa that runs down the garden to a greenhouse by taking about 1/4 of the armour, twisted and insulated, to the earth terminal. He also covered it in black insulation tape, probably to hide the evidence :roll: ...

Me too - I guess at least its accessible :lol:

BigJim, There are a couple of issues here, The main issue with rings is to try to balance an equal load on both legs, although in practise it is not too important unless one leg has all the load on it. The more important issue for you is that you can't put junction boxes under the...

I know how much you all like piccies, so here's the cable that was running a client's entire lighting circuit until a few weeks ago....:shock: The outer insulation was totally stiff so the slightest movement and it cracked completely through to bare core. Feel free anyone who wants to use...

.....with one arm tied behind his back :o Are they supposed to have rewired? The cable in all those pictures is old colours so looks like they may have just reused the existing run? That might explain why there was no earth sleeving originally, but no excuse for not adding it! If its...

The generic name you are looking for is mini trunking, such as here http://www.tlc-direct.co.uk/Main_Index/Trunking_Pvc_Index/index.html For a single spur in 2.5mm you can just about get away with 16x16mm trunking (you should not use more than 45% of the available space to allow for heat...

Hi elimn8or, If you use surface mounted trunking you can run it where you like, as it is visible and obvious, so your suggestion sounds fine. Running it behind the skirting would need some form of protection to avoid nail penetration (You can buy skirting trunking which replaces the...

Coljack, Right, saw your post immediately after I posted mine :) Ignore my previous post. Mind you, what are flex outlets rated at? I'd suspect a lot less than 27A so it would probably melt before the breaker tripped? Gavin

How exactly? Running one single or double socket in 2.5 as a spur from a 32A ring is a perfectly valid recognised method. In the absolute worst case scenario, the most you could plug into a double socket would be 2 13A plugs = 26A. I can't think of a likely scenario where this could happen (2...

You realise we are going to want more information now don't you :D I would suggest if court costs are involved, the £17 for the book is the least of your trouble! However, on Page 56, 5.2.2 (iv) states that 'accessories should be installed a minimum of 300mm from the edge of kitchen...

Had to disconnect some garden lights recently and finally got round to taking the lights off the gate posts today, only to be showered with woodlice from inside the light, and the hole in the gatepost through which the white pvc solid core cable is run. The cable has a complete N-E short...

Totally agree RF, Should have added that repair work generally isn't notifiable - and this is what any insurance would generally cover - definitely an insurance company trying to make money (shock!). I've seen a few other companies offering this now. If course, if the Government had...

See http://wiki.diynot.com/electrics:part_p:diy_electrical_work_and_the_law which will tell you what you need to know. Particularly note the following: A very important and fundamental point to note is that DIY electrical work has not been outlawed. It has been brought within the remit of...

Hi Mick, What Spark123 means is that any instrument carrying out a test at 5I must not apply a testing current for more than 40ms, unless it ensures that the protective conductor potential rises by less than 50V. In most cases this just means that the tester will stop after 40ms and give...

Hi there. A good starting point is http://wiki.diynot.com/electrics:lighting:two_way_lighting as there are more than one way to wire a two way circuit. Is this cable a new one? If so it should be the new colours, brown/blue - or could this be an existing cable from the old setup...

Is it on a two way circuit, or likely to be near the wires in one? Normally this is caused by induced voltage from the lighting cables. It generally only appears with low energy fluorescent fittings because they have a very low internal resistance, and therefore are affected by this induced...

This page intentionally left blank..... :D

Justin, To answer your original question, just replace the wires like for like in the new dimmer (making sure the circuit is isolated first!). Should the dimmer be marked differently (e.g. L1 L2 & L3) then just be aware that these normally correspond to Com, L1 and L2 in turn which can...
