No bathroom RCD {filename} | ElectriciansForums.net
 
As per pics, this is good enough for me. Window no isolator, no window isolator
 
Don't get me wrong, i always install them but if the install will be a pain in the backside, if it's got a window I can choose to exclude one
 
What book is that? It doesn't look like an approved document as per your earlier statement.
It looks more like an IET picture book guide

Indeed. It's not even the On-Site Guide, let alone BS7671. Interestingly, the On-Site Guide doesn't make any such statement.


Nevertheless, I usually fit a 3 pole isolator for bathroom fans, simply to allow the householder to easily switch it off in the event of it becoming noisy (while waiting for it to be repaired or replaced) or for any other reason that takes their fancy. (Like Midwest's midnight pee!)

That does t make it part of an approved document or the regs, just the opinion of the author.
 
Thats for a bloody great lathe or a conveyor, not a piddling bathroom fan.

At what point do you make the distinction? Can you quantify 'bloody great'?
Can you give a specific power rating at which an isolator is required?

An inline fan contains a motor, and it will at some point require Maintainence so it needs a means of isolation.
It is my opinion that a plug/socket connection is the most sensible soloution to this.
 
And there is the scenario of isolating the fan at night, so one can go for a silent pee. Not sure that's in the regs though!
We have isolators above doors. Not sure how that eliminates me kicking the bed corner and walking in to the door frame. Isolator or not, there's nothing quiet about a midnight pee when I'm involved. [emoji3]

Just searched through building regs. Can't see anything in there to that effect.
 
Read the page posted, it's all should and it is usual.
Not must be and it is required.

But it's written in a book published d by the IET therefore it must be taken as gospel and holy scripture and followed at all times by everyone capable of blindly following along like sheep and incapable of independent thought.

Not so, because we remind people that publications such as the GNs, OSG, articles in Wiring Matters, etc. are just author's opinions, not Regulations.
