Typical remainer who thinks he knows everything and then whinges when he only has part of the picture.
Remind us, which idiot who extends the virtues of being a right brainer makes an excuse as to his ignorance by saying, "Sure, but surely only after you know what 'one' is? ......."
I googled it. All of the diagrams showed there was supposed to be a fuse linking the upper and lower terminals.
Owain
I have been to India and seen the appalling quality of workmanship. That is what the article quoting Philip is referring to. What's your point?
You don't get much choice - if you buy a three core SWA or 3&E then it will have three phase colours. (Two core SWA will have single phase colours, and you would use the armour for earth)
The most common use, it to connect the brown to the permanent live, and the blue (over sleeved brown) for the switched live.
Usually one would use the black on the common connection, and the brown and grey for the switched strappers:
There is not much in it, however if you connect the feed to (say) L1, then when "on" the COM terminal is made live. When "Off" no other terminals are live. If you take the feed to COM, then you will always have an additional live terminal in the switch enclosure regardless of switch position.
You can have alter girls now, so that might need a re-think ;-)
Oxymoron?
Erm, not this one, as that wasn't an excuse but a statement of fact.
To stop being dissentious you would have to re-state that statement in context eh?
What left brainer needs that explaining .. ok, you do ...
1) Hands up who thinks moving house from A to B is a good idea (with little actually known about B after living in A for ~4 years and having a pretty good life there)? 2) Here is a limited amount of information, who want's to play 'guess the problems' (no previous skills required and no negative consequences for getting it wrong).You are very lucky, not having to suffer your own situation.

It is certainly fact you
1) You made a silly statement "Does that earth on the r/h/s foul the case / lid (is that what has exposed the earth conductor)?" 2) then whinged you you weren't given the bigger picture that anyone versed in this kind of lighting would have known. 3) resorted to abuse due to your own personal failings. 4) can't accept this as a learning experience.It all seems a common theme.
Well if it will be live at some point then it is oversleeved with brown sleeving at the switches. If using a 3 core and earth with one of the cores as neutral them it is normal to use the grey as the neutral and oversleeve it blue.
Some years ago there used to 3 a core and earth with 3 red cores. Mainly used AFAIK by BG on their CH installations. The way to identify the cores was by looking at the placement of the earth - you either had RRER or RERR depending on which way round the cable was.
That is not my experience. The red or the brown of the 3 core usually goes to common.
And I suppose I ought to let you see what the installer did to the top of the cover on a different lamp post.
Have you tried an Escape Room?
Would the knockouts have a small channel to allow the wire through without the whole knockout having to be removed (as he has done) to allow the wire through without bending it back between the terminal block and the knockout? Presumably there was no need for him to remove knockouts that were between the live and the neutral, even if he did need to remove those directly over the terminals.
Being picky, should he have pushed each of the luminaire wires slightly further into the terminal block so as not to leave some of the wire exposed as he has done with the live.
What is the normal advice with wires that are inserted into a screw terminal block? Is it normal to leave the stripped part of the wire straight or to bend it back on itself in a tight U before inserting it into the block? I have always twisted the strands (if it is stranded wire) and then bent the wire back on itself with pliers to make it wider so there is more wire for the screw to bite onto, on the grounds that a single thickness of wire, if it is smaller than the hole in the block, may get pushed to one side as the screw is tightened, so the screw only ends up biting on a small amount of the thickness of the wire, with the rest ending up in the side gap between the screw and the block.
I can see on the upper terminal block that is not used, there is a strong side spring, which I presume accepts one of the blades of the fuse which is fastened to the outer cover. And he should have connected luminaire live to that terminal. But where is the other spring for the other fuse blade, connected to the incoming supply live under the red cover?
I think I have seen all the possible combinations of it... (including one wired in three core flex with the green/yellow used for one!)
Using black on common sometimes makes the wire layout simpler since its often the middle terminal, and also the middle wire in the 3&E.
Yup - you see that slot on the extreme left of the red cover? (the slot for the fuse is on the left side of the lower terminal - and the two terminals don't line up on the fuse carrier)
I have - around Harrow, London. Very well done - really enjoyed that... Bunch of kids and middle aged blokes all working as one.
That's much clearer re: the fuse.
I wonder why they don't blank off the live incomer terminal to avoid nonsense like this?
Explain why that was silly (I love watching you faceplant).
Exactly. Ask a question of everyone and not give everyone the reasonable chance (without having to Google for more information etc). Adam knew the answer(s) so wasn't looking for an actual answer but to see who could answer (you left brainers are hard work <sigh>).
Aww, bless.
Bwhahaha ... and you know the funny thing, you are actually serious that makes it even funnier!!!
To you, of course it does (bless).
I am really happy I'm not you and sad that you are (on your behalf as you probably don't realise).
But hey, thanks for playing!

You can sort of make out the U shaped knockouts that he has just chopped off. I might have a photo of an unchopped one if you want it.
You are looking at 2mm max of exposed cable here. A close up photo makes things look worse than they are. Red red cover is not going to provide a good IP rating even if used properly.
Double or triple fold. Or use crimp on bootlace ferrules.
That was visible on the first photo. It's right behind the slot in the red cover on the left hand terminal.
It?
And whatever you are wittering on about now, no, because *I* do most of the cooking.
