New, to me, lighting wiring

[GBDamo]

Replacing some 6' fluorescents with LED panels in newly installed suspended ceiling.

Expecting to find most of the fittings wired loop in - loop out and one fitting with switched live.

However to my surprise I found the wiring as above but there was also two double sheathed single lives terminating at the fitting with the lives in the T&E linked.

The initial install was 1974, before my time, so if any of the dinosaurs can give me a few pointers as to whats going on would be appreciated.

To me your work of art says two supplies. Either two switched supplies or a permanent live for some reason. Are the T&Es connected to any of the lights or do they all just bypass the fittings and are they actually live.

The T&E N & CPCs go to the fittings but Lives are linked together and the 6181Y supplies the live to the fitting.

Both the T&E and 6181Y are present in the switches but I cant say what they're doing as yet.

I had to pull the fittings down in a hurry so that a suspended ceiling could be fitted so just dropped them and choc'ed the wiring as it was in the fitting.

Yeah "Electric Art" the new Monet wish I had the osigned original

My pleasure

ah. ok... The T&E and singles go to the switch?
As has been suggested before, permanent live taken up for emergency light which may not be there any more?
Permanant live for a smoke detector?
Looped live taken to other switch for 2-way. Pass wires being a T&E running a different route?

We'll find out tomorrow after looking at the switches?

No, just single lives but double sheathed ( insulated and sheathed 6181Y)

I think it is the switched but without belling it out..???

Have you thought about the two singles being one live, one sw, one going to each switch, strappers between the switches and L and N loop in and out?
Mind you, looks a bit strange.

With a bit of eastern European labelling?

Racialist Imperialist Impressioniate Art commands a premium.

It may be as mentioned before be a physical convenience layout, run the supply to the lights and then tap off the line at some point and supply the switches in two wire and just bring the switched line back along all the lights.

I think I recall an emergency test switch being on the far wall, thought it was for the known EM light in the lobby but it could be for this room but EM lights have never been installed, the fittings are dated similar to the original install and there are no signs of alterations.

Why would you run a permanent live to all points rather than intended EM points even if they were never fitted, bizarre.

Chris's ols man used to do the signs in Soho, was mates with Alan Poulton who my mates used to work for and Paul Raymond. I would love to be able to produce original neon's they are now all going LED.

I like this, will use it as a start point. it makes sense from what I'm seeing.

Now, I ideally want to split the room into two lighting zones each zone being two way so half the room can be on or all the room on. I know how to achieve this but am thinking the present wiring will not allow.

need a rethink methinks..

Just prove what you originally got.

Just prove what you originally got.

Sure but having an idea what you've originally got makes proving it a little easier.

This sold for £21m, so there may still be hope for you.

...And although my missus was not impressed at the extravagance,i had to get something for that bare utility room wall...

Maybe they didn't know where or if EM's were going to be?

thatis what is called Functioal Art. or FART in short. what a load of Crap.
