lighting circuit

[Sonia Norman]

Hi

I'm a recently qualified electrician and my mind just can't completely solve this one. My relative in scotland has had their house rewired. when you turn the bathroom light switch on the two bedroom lights go off and the switches in the bedroom won't work. When you turn the bathroom light off, you can work the two bedroom lights independently from their own switches. I'm guessing it has to do with the loop but just can'r figure out what. I do hope some of this problem solving becomes more second nature in future

I bet someone has recently changed the bathroom light fitting! Daz

Yes Daz they have, so you reckon they've just put the switch live in wrong? I haven't been and looked yet just trying to work it out in my head.

Who did the rewire, get them back if this has been happening since the rewire or has someone changed to light fitting since the rewire?

How is it wired?, 3plate, joint box, etc.

Apologies - read it too quickly and didn't spot it said re-wire. Doh!

Its a single switch plate, to a single ceiling rose, but it is a 4 halogen light. the switch is in the hall and the two bedroom lights are before the bathroom on the circuit. so basically when you turn the bathroom light on the two lights at the beginning of the circuit stop working.

it's obviously been wired in anticipation of scotland's independence. making sure that nothing will work right again. :dita:

Weird that, I would have expected the loop wiring would be going through the bathroom and then on to the bedrooms and that someone has taken the "live" feed from the switched side of the two way switch for the bathroom so that when the two way switch is on the other side is off.
Because you say that the bedroom lights are before the bathroom then this is not possible.
Nothing except a short circuit should affect lights before the fitting.

How do you know where beginning or the end of circuit is if you haven't wired?

Just asking

Time to get the clown who wired it back to put it right at his/her expense. Either that or it's a chance for you to look good by sorting this out. If it's standard 3 plate wiring then it's straight forward enough. Bell everything out and it's free deep fried mars bars and Tennents Super Strength for you

How would you know this if you haven't looked at the job yet?

EDIT
Just noticed post #10 (slow typer - sorry!)
