I have a 30mA RCD at my electric meter as well as a consumer unit. I wired a spur from a mains ring for sockets yesterday with it disabled at the consumer unit and tested it was off with a multimeter at the socket I was wiring from - I checked every wire's voltage in relation to the others...

Hi ban-all-sheds, I have a multimeter and will use it in future. I have just ordered one of the domestic electrical books on the wiki. Thanks

I'm in south Manchester, do you have a green copy of BS 7671 for sale, or is it just the stuff you listed? Cheers.

That sounds like a good idea PrenticeBoyofDerry, thanks.

It was attached to fairly sturdy circular conduit with a metal screw grommet and through to the other 3 gang using a plastic screw grommet. The new boxes don't align with the rear metal box to allow for this arrangement. I'd really like them in their current location. A dimmer and light switch...

I have replaced a 3-gang wall box with two individual ones. The wall is single brick/plaster and immediately behind (on the other side of the wall) is another 3 gang box which is preventing me from drilling/screwing the box in to position before re-plastering around the new boxes. How would you...

riveralt: Thank you for your help, it is working now.

If I disconnect the switch completely, so it's the live wires connected and the switch live wires connected, the lights stay on.

Riveralt: If I wire light 1 up as you describe, it works. If I wire light 2 up, also works. If I connect them both up to the one switch, they both remain on. This is how I wired it up just before you told me to as it seemed the most logical. Here is a picture, I will be using matching...

I believe the lights are on a radial circuit as the ceiling light only has a feed in and switch. I just tried attaching the two lives to COM and the two switch lives to L1 and both lights stayed on all the time. I don't think the range of switches I bought do a double pole switch. Riveralt...

Hi, I had a 3 gang unit which controlled 2 wall lights and the ceiling light. I've ripped it out and added 2 boxes. The ceiling is now on a dimmer switch. The 2 wall lights were separately wired and so each could be turned on/off individually. I want to connect both of their switch wires...

Hi Foxhole, Since posting this I read I should use a pilot hole and tried a 4mm, but the same problem occurred when I went to drill the 10mm. I re-drilled a few cm up after guessing at the brick height and it looks like the holes are all good now. I also read using epoxy appropriate for...

Hello, I'm a beginner at DIY, as you can probably tell :p. I'm trying to mount my TV, I have to drill 6 10mm holes in to my chimney breast which is plastered and papered. The first 3 horizontally were fine in to the brick. The next holes must have been aligned just at the edge of the...

I agree multi-layer PCBs are a nightmare for DIY repairs, but after all these years it shows how fundamental and simple the technology remains. Yet still, consumers are mislead in what to expect from a good PSU.

I don't see how this is relevant, if he specified a graphically intense application which in the future would require porting to multiple platforms, then sure. But he specifically mentioned Windows...

Hi Shanty, PHP isn't limited to web use, you can install PHP on your local computer and run scripts. There are even GUI bindings. I wouldn't suggest using PHP for a distributed application for regular users though. Choosing the right language and framework will depend entirely on the...

If he's connected to the internet, which being connected to the router implies, then yes he absolutely needs the updates. If it's because he doesn't have a genuine Windows key then he should get one. Having a firewall set up in the router will help for a small percentage of attacks. Without...

As others have said, you are completely wrong. While obviously a lot of products are overpriced because of brand/image, it is (mostly) different in computer hardware. Brands become well known and respected because of the quality - it is completely testable quantifiable and observable. Take a...

Thank you Mike, I'm interested in learning some DIY skills so I've just been lurking, trying to learn the basics. I am a software programmer so my math is okay, not as good as it should be. There are a lot of quizzes with explanations of the solutions on this website...
