Default Bathroom Shaver Points

We have a shaver point in our bathroom which has one output. However we
have two electric tooth brushes that need to be plugged in and wondered
if there is any adaptor than can be used. The tooth brushes are 2W each
whilst the shaver point is 50W so it should be OK power wise. Can a
european adaptor be used?

When Spouse fitted such a socket into our bathroom recently I wondered about
this dual usage. He pointed out that he doesn't shave, nor do I. If anyone
who does shave stays it's not going to harm the toothbrush thing to be
unplugged.

The answer is: grow a beard!

No. You can't use two devices off an isolation transformer and retain the
same safety. Say both were metal cased and one developed a short to case
from say L1. This is still safe, as there is no current flow through the
body as no reference to earth. Now you plug a second device in via an
adaptor. It develops a short from L2 to case. Touch both and you get the
full 240 volts. With individual isolation transformers you could touch
both cases with this fault in safety.

That's the theory - although such an event would be most unlikely in
practice.

Further more tooth brushes should be fully discharged every few months.
I do mine, my son does not bother, he is on his third toothbrush
while I am still on my first.

Does he leave it on continuous charge?

Modern ones are unlikely to have Ni-Cads so it shouldn't make much
difference discharging it or not. But I wouldn't leave it on continuous as
there's simply no need.
