Light switch wiring

Featured Replies

Sometimes I’m brave with mains electric , sometime I’m not .

Want to wire this fancy switch . Current manual switch is just the 2 browns .

Where do they go on this new switch though ? ( ‘O’ is the load ? for one of them ?? )

Do you have a meter or voltage tester? Need to determine which wire is live feed and which goes to light

Yes you will need to determine which of the brown wires is permanent L.  Then you will need to connect N to the switch (lucky this is loop at switch wiring)

Ok. So one of those brown is Live so goes to L.

 

I'll stick a meter on it and find out. I'm surprised the electrician did both wires in Brown......

 

But hasn't he tied the neutrals together ( in the box recess you can see the bound blues ).

Technically they are both live. Turn switch off, 1 will be live, one dead.

connect the permanent live to L

and the other to O.

leave the blues alone

Ok boss ( I think that’s what the midget guy said in fantasy island ) .

Does the relay switch thing need a neutral though ( to power it ) z wave

If you are wanting to add or control anything else then you will need to pick up a neutral as well.

the blues may be neutral, but not necessarily.

Yeah they’re neutral . So if say I stick a wago in there , tie those 2 blues together then add a 3rd to go to the z wave wall switch controller I’m all good ?

I’m surprised tbh . Surely the sparky should mark the L from the consumer I.e power in ( if you like ) as opposed to L to the lights ( as they aren’t live until L + L ) . Just seems an easy thing to mark when installing .

It will be, by the fact that the incoming live goes to the terminal C ( common ) and the switch wires to L1 / L2 etc. 
 

Now, more importantly, let’s have that chat about colourblind people DIY’ing their own electrical work……… ? lol. 
My dads engineer was too, and had to keep coming back and forth the office with short off cuts from the vending machine wiring looms asking which colours were which :/
