Am I allowed to do this to my lighting circuit?

[JohnW2]

Where is it stated the iso switch is outside the zones?

The isolator doesn't yet exist. The OP was considering fitting one (even though not required by regs), but didn't say where.

The recent discussion resulted from eric incorrectly advising the OP that all work in bathrooms is notifiable.

Kind Regards, John

I know the bathroom rules changed, the rule for a bedroom was combined with the bathroom so any room with bath or shower had special rules for an area 3 meters around the bath, zone 3 was dropped, but the rules for sockets was added.

I have never worked out why shower surrounds are not 2.25 meters high, that would remove a load of problems. Mine is 2.20 meters just a little too low.

You cannot have the switch inside the zones.

There may have been subsequent changes in BS7671's definition of the zones, but there have never been any changes in the 'notification rules', since they have always related to zones as defined in BS7671:2008, regardless of any subsequent changes in BS7671.

Indeed - which is why ('compliant') installation of an isolator (or any other switch) in a bathroom can never be notifiable - if it's within zones, it's 'not allowed' (hence should not be done), and if it's outside the zones, it is not notifiable.

Even a pull switch?

 

[EFLImpudence]

Even a pull switch?

Yes - the actual switch part.

 

[blup]

Yes - the actual switch part.

Ok so if the actual switch part is directly above a bath (potentially zone 1) but more than 2.25 metres from ground floor, it's outside the zone?

 

[EFLImpudence]

Yes. What point are you wanting to make?

I don't make the rules.

Exactly

 

[JohnW2]

Yes - the actual switch part.

In fact, every 'part'. Provided that the'actual switch part' were outside of the zones, I think it would still be compliant even if the pull cord were dangling into the bath water.

... and,yes, I know that a wet pull cord can conduct electricity to some extent but, like you,I don't make the rules- and 'bits if string are, to the best of my knowledge, outside of the scope of BS7671

 

[EFLImpudence]

In fact, every 'part'.

Well, no; not the pull cord. That's the point.

Provided that the'actual switch part' were outside of the zones, I think it would still be compliant even if the pull cord were dangling into the bath water.

Exactly.

 

[JohnW2]

Well, no; not the pull cord. That's the point..

I guess we must be dealing with different 'points', then

My point, which spawned the exchanges between blup and yourself, was that installing ('compliantly) a switch in a bathroom can never be notifiable (for which you 'Liked' me ). I'm sure that you don';t disagree with that,but you now seem be arguing about something

Installing the electrical part of a switch 'compliantly' cannot be notifiable because to be compliant, the work must be outsides the zones ... and if it's outside of the zones, then it's not notifiable. Installing the non-electrical bits (e.g. the cord) is not notifiable, since no part of the Building Regs (nor any other legislation of which I'm aware) requires such work to be 'notified' to anyone.

... and that seems to be consistent with my statement that 'never notifiable' applies to 'all parts' of the work - both electrical and non-electrical, since, if the electrical part of the work is compliant, then nothing requires either part to be 'notified' to anyone So, although I realise that you enjoy arguing, I can't really see what you are arguing about on this occasion

Which is the exact reason there is an insulating device included with a pullswitch string.

There's actually been quite a lot of debate about that i8n the past. Some people believe that those things are not primarily intended as "insulating devices" but, rather, are to facilitate user-replacement of most of the cord/'string' without having to delve inside the switch.
