I recently bought a Water Pik (a water jet equivalent of dental floss) but
its power needs appear to exceed that available from a standard UK shaver
outlet. The device is rated at 25VA and it appears that the standard UK
shaver outlet is rated at just 20VA. Anyway I get around just 45 seconds
of use before the thermal cut-out turns the socket off for a few minutes.
The best and simplest solution would be to find a vendor who sells higher
rated kit (i.e. integrated shaver transformer socket sets) but I haven't
yet found that.
Another solution is to just buy a transformer which meets the spirit of
the regulations (double-wound isolating transformer tested to 500V a.c.
rms for one minute between windings) but specified to say 50VA and then
hook it to suitable sockets, but I don't want to ask an electrician to do
anything illegal and nor do I wish to put my home out of compliance with
any IEE wiring or Heath and Safety regulations.
Does anyone have any suggestions?
Well I was talking about shaver outlets (for which there is a harmonised EN
standard) rather than sockets-in-bathrooms in general, which is a different
subject altogether. But now I'm trying to reacall whether I've seen a
UK-type isolated shaver point in a (mainland) European bathroom. TBH I
can't remember whether I have or not (which probably comes of being a
wet-shaver). Odd though to have a harmonised standard used in the UK only.
On sockets in bathrooms in general, an article in 'Wiring Matters' (Issue 7,
Spring 2000) which introduced the new 'zoned bathroom' regs. talks abut the
ongoing argument. Harmonisation through CENELEC seesm to have fallen apart
(again) leaving the UK free to do its onw thing. Equipment and appliance
manufacturers are very keen to see sockets allowed, but while the IEE admits
to "general agreement that a socket outlet in a bathroom protected by an RCD
is unlikely to [significantly] increase the risk of electric shock" it goes
in to say that "doubt remains". The anti lobby seems to be mainly the
government, in shape of the HSE, DTI and DETR, who "do not think that the
potential benefits are worth the risk".
OTOH 115V/5mA is 23k ohms. Would you _want_ to use a hairdryer with
insulation resistance that low?

Normally the transformer is only on when a plug is in place. If so one
could theoretically fit a miniature mains fan (eg 3") within the
fitting to cool the transformer. Result: no cutting out. However you
mustnt do this as it will probably no longer comply with BS EN etc,
and you might get it wrong and cook yourself.
I used to have a Braun one which worked fine in my bathroom on a shaver
socket, but eventually the plastic tube covering disintegrated and I've
never checked to see if it could be replaced.
