Is the transformer in a shaver socket always operating?

Good evening all.

I am tidying a spare bedroom and want to move a dual voltage shaver socket
from one place to another.
This is an MK gadget with separate 115/240V outlets.
At present the unit is in a deep surface mounted pattress on a solid wall.

I will move it to a stud wall with t&g panelling and could quite easily do
away with the deep pattress.
There is plenty of room within to accept the transformer but I am a little
worried about the heat output.
Setting it into the t&g would be a doddle but am a bit worried about the
heat ouput if the transformer is constant.

Is the transformer always on whilst it has power or does it only come live
(make heat) when an appliance is attached ?

Many thanks,

Nick.

I always thought these things only itwhen live when you plug something
into it, with a switch oeprated by the plug going in.

In any case, surely the T+G will be happy with the small amout of heat
it produces. I'd use a metal back box.

But I'm a complete amateur. I expect someone who really knows the
answers will beb along shortly.

Mine has a switch. If you look at one you should be able to see the
plunger - or if looking from the back you may see the switch. If in doubt
check the data sheet.

The transformer of every one I have encountered is switched, but I
have not examined all of them. Even when energised the heat is not
great.

However, to comply with the wiring regulations electrical equipment
must be enclosed in a non-flamable box. Put one into the wall flush
with the surface and flush mount the socket on that. If you use a
metal one make a support out of wood to fasten it to. If you can
find a plastic one for hollow walls which is deep enough you may
want to use that instead.

If you do not need the dual-voltage function and the socket is not in
a bathroom then you could replace it with a non-transformer one
(subject to circuit protection - they might be intended only for
lighting circuits)

17th Ed Regs have new restrictions on cable routes/types if the
circuit is not RCD protected - the shaver socket might be on a non-RCD
lighting circuit.
