Re: "electrical" question [wiring light fixtures]

I put all the light in my appartment with no problem! Being carefull nothing can happen. The maximum you can do is to break a bulb.

Hey Seyon, groaning at people for pointing out your advise (and this really isn't an exaggeration) could have killed them, isn't really on.

FFS WRONG WRONG WRONG the maximum you can do is kill yourself, which is really quite easy to do with mains electricity. and following your wiring advise would be very probable.

give it a rest, your advise was totally incorrect and down right dangerous, multiple people have pointed this out. If this is how you wired up your lights then I'd be getting an electrician in to double check if I where you. groaning everyone because they point this out is childish in the extreme.

Well that Seyon is because you made a mistake. groaning at anyone that groaned at you is no answer. There is never a good reason for leaving a connector block between an appliance and the electricity supply. In some countries it is illegal to do so.

If it was dodgy advice about buying a t-shirt or where to buy a TV, then fair enough.

But when you tell somebody who is unsure about what they are doing to just cut into mains electricity wires and connect them, that is not "honest advice" but potentially very dangerous if you are wrong.

Re: "electrical" question [wiring light fixtures]

Seyon,

Just to take the heat out of Bigblue2's comments....... he's right.

Fortunately my oldman was an electrician, and I've spent many years doing this sort of thing.

As a few of you have already posted..... if you are unsure, DON'T DO IT.

I'm only posting this because I know people will still try to do this anyway, so although I don't condone it, I'd rather you were at least a bit better equipped.


Nobobdy in this thread is yet to mention that they should first check the switchboard
KILL THE POWER FIRST before you kill yourself.

Isolate the 'zimmer' you are working in, and turn the power off first.


We're all on the internet reading this, so taking a moment to google what colour wire is Active, Neutral, and the Earth would be worth your life.

If you are still unsure...... STOP


(note: I've had a fair electircal 'boot' before, and let me tell you, it doesn't tickle)


Also, Don't drill into walls if you are unsure where the wires run behind them.

And the guy who wired the house also followed the rules!

I'm confident with electricity, so I did all the light fittings when I moved into my new house. I've the relevant equipment, so I was always sure that what I was working on wasn't live, as well as removing all the fuses. I also checked that what I thought was live, really was - to make sure that the switch didn't leave something live that shouldn't be. And everything was fine - and that was agreed when we had our electrical circuits officially checked.

In the photo, the blue wire I'd expect to be neutral and the green live. However... it may be just the color of wire that the electrician had to hand. ( In my previous house, which was owned by an electrician, there was one light where the earth was yellow, the live was yellow and the neutral was... yellow ). If you have any uncertainty whatsoever, get an electrician in. Any wiring can be anomalous, and I'd rather the sparky got a shock than I did. Cos they really really hurt!

It's too easy to make a mistake that can have very serious consequences.

On of the main causes of injury is not the actual shock when touching a live wire (although if your other hand is holding onto something earthed, like the earth wire, for example, the shock could prove fatal); but the trauma injury from landing after falling off the step-ladder or chair whilst wiring up the socket when you get thrown off it.

It's safest to assume that everything is live (even with the fuses out) until you have proved otherwise.

That's fine, but we shouldn't loose sight that the thread started with the OP not knowing what to do.
As long as we're all offering constructive advice. No point in derailing the thread with useless arguments.
I was never questioning your ability, but if the OP has to post a photo and ask an obvious question....... you gotta assume he's about to do something bad.

3 yellow wires is just nuts.

spot on!

I was working on a monitor a few years ago, it was turned off at the switch but unbeknown to me the switch was faulty, it blew me across the room (about 4 meters) and I fortunately landed on a sofa, gives you a nice dead arm for quite a while too

Re: "electrical" question [wiring light fixtures]

I asked an electrician once if he ever got shocked. He said,"that's like asking a plumber if he ever got wet!".

Assume every gun is loaded, every wire is live, and that mystery blob on your fondue fork is garlic .

I've got thrown across a room as well - but I had a solid wall and not a sofa to land against.

It was 400V which feels a lot worse than 240V mains.

Thankfully 400v circuits are usually wired correctly to begin with. Only odd thing is many older ones are 4 wire rather than 5 (3 live, one ground), and it is apparently acceptable to tie a jumper from the ground prong to neutral so that 240v plugs can be used. I've wired a lot of machines and cables but still call a pro when I need work on live 400v circuit.

Actually, in my case , I was quite young and was trying to fix my oscilloscope. I touched the metal case of one of the transistors to see whether it was hot (in a thermal way) and it was at a potential of 400V.
Still, lesson learnt.
