electric shower

i have an electric shower in my bathroom on its own supply 30 amp from the consumer unit, it is operated via a double pole pull switch, is it at all possible for me to wire in a shower light and timed fan from this so all come on at the same time? or is it a no no and will need a seperate lighting circuit via a fcu to power both??

Jonah, there is a way to do this using contactors and a fused spur, if you honestly beleiev you can do it say so, HOWEVER, you really will need to understand what your doing. It is a system I have installed personally, and my guys install on a regular basis.

The wiring seems complex, it isn't really, but you will need to have a good knowledge of electrical circuits to fully understand this.

If you interested... shout

OOI - why contactors rather than just multiple cables from the switch?

Many reasons, safety, practicality and actually getting multiples into a pull cord is nigh on impossible!!

You do not need a 45A pull cord to do it either.

I'll sort out a wiring diagram for you to act as a Guide.

But as discussed on an earlier thread, only 1 is a fat one, the other could be 1.5 or 1.0mm..

Now that is very true - 45/50A pull switches are ugly bvggers.

Ban, the reason for not using a 45A pull cord is more to do with simplicity and practicality that looks..although I agree they are the Geof Capes of the pull cords!

When I post the wiring diagram you will see what I mean.

I'm creating a new one from scratch as our scanner is playing silly beggers and refuses to scan!

OOI - have you (or anyone) ever seen flush, square pull-cord light switches as a neater alternative to round surface-mount ones?

No , but if you have a circular pullcord switch that has besabox fixing centres, then you can buy a round drylining box, the sort you can fix a ceiling rose to, and fix the switch (less the pattress, of course) to that.

like MK for example.

I have seen square pullcords, however I do not know their rating or their manufacturer as I have never had personal contact with them.

I think that Crabtree used to make one many moons ago, but I dare say it has been dropped from their range..bit like their website
