2 way switching

[Nick M]

I’ll try not to make this too long but

Can anyone tell me if 2 way switching in France can be carried out using multi-core rigide cables (RO3V to 1st switch and RO4V between switches) or is it all done in gaine with single cables as this is the only method I’ve seen in my French wiring book. And I have not seen the 4 core (3 + Earth) cable in  brico depot although I seen it in their catalogue

Also if using single cables do the switch feeds, switch lines, strappers ( L1 & L2) and common conductors have a specific color codes, because I;ve only used multi- core rigide cables so far with brown and black conductors.

Thank you for your answers

Much easier to do with single conductors in gaine or moulure. No specific colour codes although I have tended to use orange or purple for the L1 and L2 (navettes). You can use anything you like except blue (neutral) and green/yaller for earth.

Up to 7 core 1.5 cable rigid is available from memory :  Yellow/Green (Earth) , Blue (Neutral) and Red, Orange, Black, White, Purple and Brown. Never found any offcial code on pairing of colours. BricoDepot and Leroy Merlin do stock both reels and sell by the meter 4,5 and 7 core.

You can and as others have said (N & E apart), the colours are unimportant.

However, if you are doing a 2-way circuit, the "strapper" consists of 3 wires only and you will find it far far cheaper to use 3 single cables than a 5-core. If you have more than 2 (or even 2) switches, use a télérupteur - only 2 wires (one of which can be neutral) to each switch.

Then again, Legrand do a super range of radio switches that need no wires at all!

Thank you for your advice,  singles it is, as the multi core would have to be in gaine any way as it will be in partition walls and false ceilings with no access for rewiring.
