8 gangs of 2 way light switches - wiring

Michaelwgroves · Jun 24, 2022

If you were wiring 8 gangs of 2 way light switches. Would you wire 8 independent circuits, so 8 no. 3 core between switches. Or would you run a live, and loop all the L1's together, then just run 8 no. 2 core between switches ?

Eight gang switch in a dwelling that won't cause confusion.

Not when it's all labelled

Only his legs., put your wiring diagram on here and we will look at it.

That'll look nice. My mum has a two gang switch in the hall one switch for the hall the other for the landing and for the last fifty years she clicks on and off until she gets the right one. I reconnected it and said near switch hall, far switch landing but it made no difference.

I couldn't decide whether a pencil scrawl or printed label would look worse, so left that the imagination.

Yup, I know CY/YY/SY is not 'approved' under certain UK regs because, as I understand it, it was too much hassle and expense for the manufacturers to bother. So one writes it down as a departure, used for good engineering reasons and to equal safety standards. British Standards publications are not law, only a guide to one (good) way of doing things.

As with a lot of publications of this type while they are not statute documents they can and quite often will be used to support a case litigation

The other problem is that of subsequent EICR's especially if the original certs are lost there will be no record of your departure and could potentially see the installation classed as unsatisfactory due to the non compliant cable and the inspector not having the same viewpoint as you

Mark42 said:
Otherwise, why are these excellent cables even sold in the UK? ...

As previously posted they are control cables that are generally used in industry for machinery control circuits which are under numerous other British Standards

Mark42 said:
I'll argue with anyone that my occasional use of SY is better than say cr@p flimsy T&E clipped to a wall in a public building. The latter is entirely compliant, but that doesn't stop it being cr@p.
I rather like having that earthed braid over everything, cf. Flexishield of which I also use a lot.

How far would you argue your case with a man or woman wearing a funny wig or the expert witness that they may get to give evidence against you

Every cable has it's limitations as to whether it is crap is open to interpretation, the question that needs to be asked is the cable crap or has the installation method rendered it so.
Personally for me the crap cable is FP and it's derivatives you see it more often than not incorrectly installed so much that IMO it should be banned from use as a safety cable and we should go back to Pyro / MICC for fire alarms

I’m intrigued, how have you seen it installed incorrectly?

If you read the manufacturers installation instructions for FP it should only be clipped with metal clips or ties but so often it is fixed with plastic knock on clips, plastic cable ties and other similar fixings that melt in a fire and allow the FP cable to fall and then it will not maintain it's fire integrity under the BS to which it is tested

get an electrician in for this work. You could always do the chasing and floorboard lifting. No offence intended, but at least you know it will be done correctly and also certified.

Sorry to disagree, but getting an electrician in doesn't ensure it's done properly

Seeing the state of some installs on YouTube there are a lot of incompetent sparks out there wiring up houses

Fair point, I should have said get a reputable electrician in.

I would love to see a pic of the 8 gang after it's been labelled up because I'm tying to picture it in my mind as to how aesthetically pleasing it's going to look in a domestic environment.

Unless hidden under the stairs, I can't see any nice way to label this in a domestic environment. It's likely that whoever wants a bank of 8 switches will memorise each one, while everyone else in the hose will try them all and leave lights on everywhere.

I engrave stuff a lot, this is in my hallway. To make this more discreet I could have filled it with white wax, the white wax colour is different enough that you can read it up close but from across the room it looks unmarked.
