2 gang to 3 gang light

Mod Note: Member is in Ireland.

Hi,

Moved into "new" house last year and of course I've been changing things around - not too new house - build in 70s, but in pretty good condition. I've done some wiring in bedrooms etc, but I got stuck in the garage. I've a 2 gang switch - 1st switch for a garage and 2nd for a bathroom. I'm planning to divide garage area into 2 separate rooms, so I need and extra light and that's where the problem begins...
I found a pic that should work for me:

but please check wiring in 2 gang at the moment:

LIVE - power supply - 2 wires
SWITCHES - lights - only 1 wire each

and of course I've bought 3 gang (same as on 1st pic) and 3rd light which has 3 wires (blue, brown, yellow).
So I've tried few times, but cannot make it working. I don't really know why SWITCHES cables have only 1 wire. Is second behing a box? Or am I missing something?
Any ideas please?

This is primarily a North American forum. Our switches and wiring are somewhat different. The diagram does though look correct assuming power comes to the switch not the light.

I don't know either. A switch cannot work with only one wire. No matter where you live or how devices are typically wired, a hot wire will either be connected to a device (always on), or a hot wire will be "broken" via a switch to allow you to turn it on and off.

Please post a picture of the front of the switch you show above.

Why wont my USB port power up? (Game controller Tower DIY)

J

Jimmie Mitchell on Oct 30, 2014

So I made a controller and headset tower for my gaming accessories and decided to add LED's and a USB port to use to recharge my headset. I used 3 strips of 12V LEDS each with about 15 LEDs in a strip. The USB port is the kind you would plug into your cigarette lighter in your car. When I tested the USB port on the 12V power input without LED's it powered up perfectly. But when I have the LED strips powered up along with the USB port. The USB port is getting significantly less power and is not strong enough to charge a controller or headset. Along with this project I have been making a video tutorial on how to make your own. I havent ran into this kind of problem before and wanted to know if anyone could help me out. It should be possible to power up everything with one power input, Right? Here is a link to the first video I did of the project.

It doesnt have anything to do with soldering or power or anything. However here is the project today! [ATTACH]40963[/ATTACH][ATTACH]40964[/ATTACH] I would really love to get this problem solved! Thank you for reading!

New 30A circuit through existing EMT

M

marshall1981 on Nov 08, 2014

Hello, I'm running a new 220V, 30A ckt, and I'd like to do it through existing EMT. I found NEC tables online stating how many conductors are allowed in 3/4 and 1/2" EMT, but theyre all for a single gauge. If I add the circuit I'd have a short section of 3/4" EMT with seven 12g conductors and five 10g conductors. Then I'd have a longer section of 1/2" EMT with three 12g conductors and two 10g conductors. This includes the new circuit. The NEC table shows the limit of 16 12g conductors and 10 10g conductors for 3/4" and 9 12g and 5 10g for 1/2". Finally, its ok to use the existing 12g ground wire thats going to an existing 120V outlet on the new 30A, 220V circuit correct? Only the two hots need to be 10g? The EMT is also grounded. Thanks Marshall
