Wet Locations

[Cookie]

In wet locations a body resistance of 200 ohms is assumed, and disconnection times go down to 0.2 seconds in a 230 volts supply (0.4 110 volt supply), is that correct? Or is this not required in BS7671?

No sockets in UK bathrooms? Why not? And why not rocker switches?

Your original question answers this!

Add an iffy extension lead and you can have the Horror movie with the toaster in the bath!

Rubbish. Normal switches have always been allowed in UK bathrooms, and I've fitted plenty of them. The old regulation was "not in reach of a person using a shower or bath", which is more than the current zone 1 600mm.
Suitable for the environment is another argument, but Crabtree issued guidance, when they introduced the 4000 series, that they were suitable.

Never have seen one and never would fit one

Seen plenty, especially in commercial sector. Fitted some too.
JW has strong views on the "manky string" variety!

People getting out of the bath dripping wet, and combined with a possibly damp/steamy atmosphere.

Still doesn't make sense. The switch plate, screws and toggle would not be energized.

It does on the basis that BS7671 fails to require a faster disconnection time.

IEC61200-413 assumes 200 ohms in wet locations and allows for a maximum of 0.17 seconds.

What stops someone from taking power from the hall receptacle?

Switches in most domestic situation tend to be on the outside ??

Yes, in my en-suite at home someone did that.
Everyone's free to do what they like of course.
My only point is that the commonly believed and followed "Thou shalt use grubby string to operate bathroom lights or put switch the other side of the door" law is utter rubbish in most situations.

Interesting post above from @Cookie that I'll try and understand when the kids are in bed tonight!

Hopefully common sense!

I think switches on the outside are stupid, an excuse for party pranks, etc.

For most large bathrooms then a switch on the inside is perfectly safe, though obviously only if sufficiently far away from the source(s) of water like bath, shower, sink, etc.

I don't see anythinbg wrong with pull switches, you can change the string if manky ithout too much trouble as normally there is a plastic coupler ner the top. Various DIY places sell replacement string/knob for them. They make sense in compact toilet/shower stile places where you cant achieve a sensible safe distance in any practical manner (e.g. shower cubicle next to door, etc).

Looks like JW agrees with me! Part of the problem is, like in most rooms, who has just one light in a room any more?
I find that the average bathroom I fit out requires four switches minimum (downlights, downlights, mirror light, extractor fan). There can be electric towel rails and electric UFH on top of that.
It would look pretty silly with a row of (colour coded?) strings hanging from the ceiling.

LOL! Just need a monk's habit and start practising campanology!

Fitting a new pull cord switch and Fan isolator on Tuesday .Old lath and plaster ceiling .So plan to use a good switch and a piece of ply to act as a backing board above the old ceiling .Gives the thing more chance of never been pulled off .Proximity switches seem also to be a "thing" now
