Are the additional wires (the red and yellow) within the new light? If so, are they already connected to the main connection block within the light? OR are the additional wires (the red and yellow) part of the original house wiring? If so then the additional wires (the red and...

The "tiny" bathroom comment and saving room by having an integrated light in the shower makes me think that the whole ceiling is essentially in zone 1.... I hope its not low enough to be in zone 0 :)

No I haven't seen anything either. You may need to go with a standard fan and mayb one or two of these: http://www.tlc-direct.co.uk/Products/FRSHGUC.html

If you have an existing 4 inch (100mm) inline fan in the ceiling then I am assuming that it is connected to a vent kit? If so then you could try the following system if you want to replace the whole thing: http://www.tlc-direct.co.uk/Products/MRSL100TC.html Or do you just want to fit a...

You need to take the cover off the shower and use a safe voltage measuring instrument to confirm the presence/absence of mains voltage. Don't use a neon screwdriver since it will not confirm whether the neutral is present/intact. If you have full mains voltage then the shower is faulty...

Just an observation and only out of curiosity, do you have an extractor fan connected to your lighting circuit? I think most applications of two way/multi-way switching have the 3core+earth between switches so you probably would not see it at the ceiling rose. However, switching for an...

Yes thats a good point regarding rectifications of problems. In the long run I think it did do me some good as far as being assessed. Of course at the time when the test failed I was sure I could see the coast of Autralia through the hole that opened up in the ground :) I was pleasantly...

Its a pass!! thanks for all your advice. Would you believe that an RCD (Wylex) failed during the RCD test during the first inspection!!! I had a spare one, put it in and all ok again. What are the odds of that happening??? I had just finished showing him an r1+r2 on that circuit...

Thank you all for your advice. I eventually found the earth rod under the main entrance floorboards. Had two 10mm CPCs connected to it. One CPC went direct to the main earth of the CU (the CPC that I could see when I changed the CU) and then another CPC which went all over the place but...

Got permission from the house owner today to lift the carpet and floorboards!! Will be doing that tomorrow and will keep you posted. 8)

and thanks to you too Widdler :D

thanks electronicsuk and RF Lighting, Yep, I must admit the 0.9 seems like wishful thinking for an earth rod and I did not consider an older service that might be providing an illegal earth. I did seperate out all the existing bonding but I take on board that can be sure of nothing without...

Thanks 1john, thats good to know about the switch. I would have kicked myself for failing on that. Of course I could have changed it for two seperate switch plates but the customer would not be too impressed with that anyway. Regarding the earth rod on the other installation, I did measure...

Hi all, looking to you good people for some NIC advice. have been in the industrial electrical/electronics game since 1976 and yes I am older than the pyramids!! business went bad last year and I moved into the brick dust and floorboards of the domestic world. Despite having an electrical...

Sorry I posted in the wrong forum. Have moved my post to the electrics UK forum.

Some good points here, thank you. I really should test the RCD in isolation tomorrow and it may well be the RCD itself... An electrician in a suit!!! that will surely generate more web hits than last nights X Factor!!

With outgoing circuit connected. Was going to test in isolation (at the CU) but the house owner wanted to lock up for the night (empty property) Going back tomorrow. BTW, Ze was 0.19 (T-N-C-S) Thanks,

Hi all, I am part way through installing/testing a new consumer unit (going back tomorrow to complete the testing) Ground floor ring (2.5mm wire, 32amp MCB, Crabtree 30ma RCD) RCD test does not trip the RCD at 1X, 180 deg (negative half cycle) All other RCD tests are good including...
