Bathroom Light and Switch
 

I visited my daughter in Edinburgh at the weekend and found some
strange wiring.

There were three red conductors attached to the pull switch.
Although I didn'tdisconnect the conductors to check the
markings, there was one terminal to one side of the switch and
two toward the other side.
So I was thinking that this is probably a two way pull switch with
a single common terminal and L1 and L2.
But, when I checked the behaviour of the connections, it appeared
that the constant live was connected to L1, the switched live to
common and the third red conductor attached to L2 didn't show as
live whatever the switch position.

All I can think is that the switch has been incorrectly wired.

Any ideas guys?

Thanks

Phil

Anther switch somewhere that also turns on the light - this second
switch switches live to L2?

Any fans, shaver points etc in the room not working?

If L1 is the perm live then you cannot of course make L2 go live!

Interesting idea, the wiring certainly is weird, but I can't
think of another switch that would be feeding live to the one
under investigation.

Hi Adam

There is a light fitting further into the bathroom that doesn't
appear to have a live feed to it at all!

My thoughts were that the switch had been incorrectly wired, but I
wanted some informed opinion on this.

The bathroom has two light sources, one being a couple of spots
driven by a transformer. These are fed by the switched live
successfully. There appears to be some twin and earth heading
from the switch in the general direction of the dud fitting. The
daft bit is how the dud fitting is fed. A ceiling rose attached
to the original ceiling has drop flex passing down through a
lower suspended ceiling into the dud light fitting.
The rat's nest nature of the wiring and my limited time there left
me less confident of disconnecting stuff in case I left her with
less operational fittings.

I had one of those.

2-core flex feeding a class 1 luminaire with no IP rating in Zone 1.

Our previous pull switch in the bathroom was wired in a similar way with only three single reds the difference being two Reds were connected to COM and the remaining red to L1 which turned out to be the switched live to the light. This method of wiring was consistent with all the other light switches. The live loop in was done at the switches rather than in the rosettes, neutral was provided by a single which simply went from light fitting to light fitting.

In my opinion I feel your switch has been taken off at sometime and replaced incorrectly, check some of the other light switches it may be that your lighting circuit has been wired similar to mine.

I think the only way we'll get informed fact is if you see if the unlive wire feeds the dead fitting. If it does & you swap the swL with L the switch will then light either one of the fittings but never both nor neither:) If tha unlive does feed the deadun it sounds like a very easy job - if the dead fitting is fit to receive 240v.

The wiring won a prize?

I wonder where the other red went?

Timer switch in series to turn it off after a certain time?

I once found black wires entering a fuse carrier in an old CU, and for a brief moment was puzzled. They had turned black from the heat.

I suspect you are right. The dud fitting is an LED jobbie so must
be fairly recent.
This will all have to wait till the next time I go up there and
investigate.
