Folks,

I recently replaced the shaver socket in the bathroom, and boy ... do I
feel cheated. The old unit had two outputs one labeled 110v the other
220v with an external switch to select one or the other. I have both an
electric toothbrush and an electric shaver and I was fed up having to
keep track of which was being charged and for how long. So I replaced it
with a 2 gang MK shaver socket from B&Q which had two outputs and no
switch, one marked 110 and 220. Since both my devices will run on either
110 or 220 I intended to plug in both simultaneously and it would not
matter about the different supply levels.

However it turns out the MK unit was switched, it had an hidden internal
mechanism operated by insetting a plug. Only one of the sockets can be
used at a time. A real pain. This was not marked on the packaging
anywhere. I phoned MK and they gave all kinds of guff as to why things
were the way they were. Interestingly the support guy did admit that
these devices were designed decades ago and were not intended for
continuous use, even if this continuous use only involved having to
support trickle chargers. Some shaver sockets tended to overheat and
would cut out, if say a shaver was left continuously plugged in! This
has apparently been fixed.

However my question is has anybody hacked these units to allow both
sockets to be used simultaneously? I am interested in any thoughts as to
wiring the transformer's output to both sockets, and bypassing or
disabling the switch. Assuming the transformer only has one secondary
winding which is tapped to provide the 110v output. Should I use the 110
or 240 winding?

Thoughts?

There is a single 1:1 transformer inside. The secondary is centre
tapped to give the 110 volts. So if you used both sockets
simultaneously you would overload the common part of the transformer
wire.
So the switch is fixed so you can't.

I would have been surprised if the two sockets could have been used
simultaneously and I would have assumed there would be a regularity
requirement that they can't.

Cue someone who knows.

If they did work the way you wanted then it could be a (roughly)
centre tapped secondary winding to give 110 and 240 or it could be two
separate windings which with an in phase link in place would gibe you
a 350volt supply in your bathroom. I know it's unlikely to happen by
accident, but still.
The same could happen with multiple isolated outlets near to each
other, I wonder if there is a prohibition about this?

The other problem is that, off-load, the 240V side is allowed to be
up to 270V (due to poor transformer regulation). Chargers often look
pretty much like no load, and can end up getting 270V. If the charger
has a wide ranging 110-240V supply, it's often better to use the 120V
side.

Socket has to cutout at loads over 25W, but this doesn't need to
be quick, and often relies on the transformer overheating and a
thermal trip.

A bit OT, but I find trickle charging cordless devices heats the
batteries and reduces their life a lot. Better let them discharge
fully before charging and they should go for a decade.
No doubt others will disagree.

Running two devices off an isolating transformer negates the point of
having one.

That is the point of the transformer. The secondary side is not
earthed so you can't get a shock.

Well I would need to fit another shaver socket or move the existing
one... however point taken. But both my shaver and toothbrush are
cordless. But is your scenario any different from using the shavers
single output and droping the charger into a sink full of water while
holding the tap?

Given the above scenario above I do wonder if my houses built in current
leakage protection is better than the decades old isolation transformer
technology that is built into shaver sockets.

Why? Is this based on a worst case of it being able to touch any single
wire safely? Touching two wires would still give a sock, isolating
transformer or not?

Probably not a toothbrush - mine doesn't get even luke warm even if it's on
charge for 6 hours past full. I do tend to wait until the light starts
flashing before recharging as it's not inconvenient and avoids the
requirement for a full discharge every X months.

These shaver sockets are current limited anyway but, assuming it can

That's how I power my toothbrush and radio off a single socket.
Actually, mine is a 3-way adapter which I think I bought in Indonesia -

It does assume you have two faulty devices, etc. However, the isolation

Not if you're referring to your latest post they're not. To get a shock
the person has to be across both output pins of the transformer. Either
pin can be dragged to earth without a shock. That's why it's called an
isolating transformer.

I did drop a live light socket on a lead into a fish tank and put my hand in

At best it was a tingle and all the fish just swam about as normal.
I don't think I will do it again but I was only about 10 at the time.

Of course statistically its insignificant and YMMV.

I've been reading this thread and I'm left wondering two things:

These isolating transformers seem to have been around for decades,
whereas RCDs seem to be a more recent invention. Reading Graham's
comments (above) is there an argument that bathrooms would be safer if
the socket had no transformer and was wired direct to a 30mS RCD?

The other thing I wondered was if the OP decided to fir two isolating
sockets, one for each device, or if you had a big bathroom with his
and hers sinks and each had its own socket, would two sockets be just
as dangerous as running two appliances from one socket?

I'm not an electrician, so I don't know but as the output from the two
transformers would be in phase, if you held pole 1 on socket 1 and
pole 2 on socket 2, would that have the same unpleasant effects as
holding poles 1 and 2 on the same socket or am I barking up the wrong
tree (if so, I did say IANAE)

Two isolating transformers are the way to do it. You can safety touch one

Isolating transformers are designed to fail safe even in a
burn-out scenario.

When RCD's fail it's usually unsafe, and silently.
(Fortunately, RCD's in the EU don't fail at anything like the
rate they do in the US.)

No, separate isolating transformer per appliance is the correct
way to do it.

has apparently been fixed.

However my question is has anybody hacked these units to allow both
sockets to be used simultaneously? I am interested in any thoughts as to
wiring the transformer's output to both sockets, and bypassing or
disabling the switch. Assuming the transformer only has one secondary
winding which is tapped to provide the 110v output. Should I use the 110
or 240 winding?

Thoughts?

I am using electric toothbrush and Internet radio at the same tie my my bathroom, the one i am using works well!

.. Some shaver sockets
tended to overheat and would cut out, if say a shaver was left
continuously plugged in! This has apparently been fixed.






Slightly worrying - my 1988 house has a MK Socket and there is always a
toothbrush plugged in,

Per my other thread, I fitted a double Schuko socket (not inside the
bathroom) which solves such problems.

It would be a very poor transformer indeed which came to harm due to being
powered up at all times with no load - think a bell transformer.

These shaver outlets often hum. Having it switched when not in use stops
this.
