now i have knocked down 2 stud walls the wiring to the bathroom lightswitch
is now in effect inside the bathroom, runs down the wall next to the new
bathroom door. the switch remains on the outside of the bathroom.
can i leave the switch wire where it is or does it have to run outside the
bathroom. it is know where near water, the closest being some 10 foot away.
I'm not sure of the regs about your wiring, but it's abit iffy to my way of
thinking. I know the switch must be outside the bathroom so that you can't
switch it on with wet hands etc.
But since the wiring is accessible, why not shorten it and fit a pull switch
screwed to the ceiling? Much better all round IMHO.
It sounds like you have surface mount wires running down the wall inside
the bathroom, which then go through the wall to a light switch outside
the bathroom. Is that right?
Provided the wires are of appropriate cable and adequately supported,
they are fine. Many old houses have surface wiring.
You are no longer allowed to do anything other than replacement of
wiring and fittings in places like bathrooms, Part P rules. You are not
allowed to modify such wiring, say to re-route them.
Of course, had you re-routed the wires before knocking the walls down
(so that they weren't in the bathroom at the time), that would have been
fine..You could have, for example, replaced the existing switch and
cable with a ceiling-mounted cord-pull switch (which happens to now be
in your bathroom)..Are you sure you didn't ;) ?
If you do need to modify bathroom wiring, you need to either get an
electrician whose company can self-certify to Part P, or the work needs
to be notified to your local building control body:
"Work, including minor work, which is carried out in a special location
as included in Table 2.(Replacement work is nonnotifiable, even when
carried out in a kitchen or in a special location shown in Table 2.)
Locations containing a bath tub or shower basin
Swimming pools or paddling pools
Hot air saunas
Electric floor or ceiling heating systems
Garden lighting or power installations
Solar photovoltaic (PV) power supply systems
Small scale generators such as microCHP units
Extra-low voltage lighting installations, other than pre-assembled,
CE-marked lighting sets
