Are these wires neutral?

[Stevieg2]

I'm currently in the process of running neutral wires around my house to all the light switches so that i can install some of these new wifi smart switches to control all of my lighting.
One of my light switches has a black and a blue wire connected together separately from the switch shown in the attached photo.

How can i tell for sure if they are neutrals?

Basic test equipment and basic testing skills will identify the wires.

I've tried putting a multimeter to them and between live and the unidentified wires i get zero volts.

What would you suggest?

Time you have the switch off a tidy up would not go amiss

 

[Stevieg2]

Dug out an old multimeter with longer wires to test the continuity between the switch and the light. Turns out they are neutral.

Win for me as i don't have to run a neutral to this switch now!

I'm curious on how you are going to run Neutrals everywhere.
(without ripping your house apart! )

All the switches are on stud walls. Downstairs are close to the landing which I'm waiting to carpet and then upstairs I'm going to try running them down from the loft. Will be interesting to see if it is possible or not.

Ah, OK.
Trouble with stud walls is them damned noggins!

What type of wiring are you using for these new neutrals.

1.5mm single core cable

They will require suitable enclosure/protection if they are not pvc/pvc insulated.

This should be ok.

Yes but not 16.0, you can get 1.5 though but can be hard to source.

It's an off-the-shelf item here at wholesalers, though from what I gather is extremely uncommon in England.

I've put a funny because I though you where joking. Now I've thought about it I'm not sure if you were!

I actually thought it was on the shelf everywhere what do you do in England when you require it?

AFAIK many contractors there would run a T&E with unused cores. Perhaps someone from England could clarify?

Interesting, there also seems to be a lack of twin brown from what I've gathered on here

Can get twin brown in Scotland ok but most of the wholesalers round my way need a few days notice to get it as it isn’t often used. Usually when you ask for it you get normal t&e and a lump of brown sleeving.

And here it's unheard of to wire switch drops in brown & blue.
