Landing and bathroom switch wiring

[ipf]

I'm not wiring a house here it's just a switch what's the big deal

Why are you asking, then?

Anyone can presume or guess, even, from afar but can they be certain what goes where? As has been suggested, call someone suitably qualified to test as required.

Read post 6 and take it in.

This web page shows a standard three wire two way switch wiring, this is what may be in place for the landing light if it is switched at top and bottom of the stairs.
The bathroom switch may be independent of the landing switch.
We cannot tell from a distance which cables do what, without seeing the wiring and testing we cannot safely advise.
If you want to use the website diagram then that is your choice, but do make sure it is safe and you are safe.

It's just to lives with through lives though isn't it so in reality no matter how there switched it's not dangerous

...I would not normally get in the middle of one of these debates...but...your phrase of "lives through lives" is a worry...

Firstly,you will/should not have lives connected together. There will be lives,both permanent and switched,and there will be loads. Also,there may be neutrals,and earths.

One situation,where you will not have an explosion,or fuse blowing,but is nevertheless a concern,is where you may connect,inadvertently,lives from two separate circuits,say ground floor and 1st floor.

This would leave the possibility of a circuit remaining live,with its' labelled MCB,turned off.

It is for reasons such as this,you have received some posts,although jabbing at your pride, are given,in an effort to save harm.

If you would be generous enough to furnish the forum with your occupation,i will guarantee i can come up with a parallel question,which may give you an indication,of the quandary we are facing.

Check the downstairs switch to see which core is used as common (usually yellow) put this yellow to common put landing light red and 3core red to L1 and black of landing light and blue to L2. Other switch is bathroom with red to common and black to L1. Switched lives need indicating and safe isolation procedures followed. Good luck.
P.s you dont need any links between the two switches as they already have there own feeds and doing so could create a danger!
