That sounds about right - would fit in with the ELCB that I've just replaced too. Only thing is, they had much more recent cables added to, in a large junction box under a floorboard, underlay and fitted carpet :evil: Last bungalow with loft extension I do for a while! Thanks for the...

Tracking down and removing some nasty old wiring today under floorboards, and in a large junction box discovered several cores twisted together and secured with what I believe are called 'wire-nuts' in the States, or twist-on wire connectors. These were made of moulded ceramic, with internal...

Ok, that was my next guess :D Actually drawing it out I can see it works - I got the switched live and the strapper to the switch downstairs round the wrong way. Still not sure if these are singles or twin red cables, but it seems to show a drawback of twin red or twin brown switch drop...

Bright, Thanks for the diagram, I think I have it now :D If I'm right, the following should fix the problem. The red in COM, switch A needs to be switched with the red in L1, Switch A. That will fix the 2 way switch, but you will also then need to move the short wire from COM Switch...

Bright, Click here for some details on how to insert an image in a post. No reason a woman shouldn't be able to do electrics :D Though you've chosen one of the more difficult wiring problems to start your sparks career with! You are not too far from the right layout, but some of...

Hi Bright, You aren't the first to discover that there are two or three 'standard' ways of marking light switches. To give detailed advice, a diagram or picture of the back of the switch would help, showing the cables, colours of core wires, etc. If I read your post correctly, you will...

ts not a great drawing, but there is no point in connecting the earth tag from the pendant lamp, unless its then earthed through the lighting cable. You need to connect both earths to that earth screw to ensure a continuous earth. That of course assumes your lighting circuit is correctly...

Ah, That voltage ELCB pic is exactly what I will be replacing next week with a 100ma RCD in a TT installation. The interesting thing is that when the kitchen was done in 2005, the installers spent ages digging to fit an earth rod and get an acceptable Ze, then left this protecting the new...

A CU change, and a CU change with a more or less complete rewire (both parent's houses) And yes he particularly checked supp bonding on both jobs. In fact that and the Main equipotention bonding were two of the things he was most careful to check. Gavin

Sounds like the type my father has in the bathroom. When I looked into it a bit, it seems that in Zones 0-2 certain IP ratings are required, but not in Zone 3. The NICEIC man saw it when doing my on site inspection there and didn't comment either, so it would seem it is ok. Having said...

Thanks, I guessed it may simply be a cost issue. I'll take note of those makes, but the client always knows best :lol: so I suspect I will end up going with all in ones and warn him they may not last... Gavin

...to why I am replacing these ones, probably! (they were apparently purchased from Costco and have an alarming tendency to fill with water). However, my supplier poo-pooed the all in one units last year when I was looking to replace a B&Q twin PIR38 spotlight at my mother's house, so the...

Just wonder if anyone has any experience to offer... Will be replacing some American PIR lanterns shortly for a client. Previously, when I asked my local electrical supplier for pir lanterns he said he didn't stock them because he found they failed regularly and came back, though he was happy...

I know you all like pics so thought I would share this. Can I claim the prize for least accessible switch of the year? Currently trying to sort out a 50s bungalow thats been messed around with over the years and is in a right old state. I initially was puzzled by a circuit still...

You are allowed to run cable in 'safe' zones without additional protection, and one of those safe zones is along the top of a wall (although some people don't like that method) http://wiki.diynot.com/electrics:installation_techniques:route has more information on those routes. From what...

Hi Marc, I've had the 1552 for a few months now and been very pleased with it. The only difference between it and the 1502 is the automatic RCD test which might save a few trips to the CU if you are on your own. Generally seems to be well made and easy to use. I got mine from iswww and...

I use a Megger too, the 1552 which has the auto RCD testing and saves your legs if the circuit and CU are a distance apart. So far I've found it excellent - the only issue I've found is that the readings for standard and 'no-trip' ELI tests can be wildly different, but I gather that is more...

I've found Smartdraw quite easy to use for the drawings I've had to do recently. It has lots of electrical symbols, but none of the 'standard' BS ones that all the books use, so I just suitably labelled boxes and a key

Hmm, I wonder why :shock: :o That's an impressive level of corrosion - was it a very old box, or had it been located under a dripping tap? (or in the bath?!)
