Isolator switch
 

I will be putting a 3-pole isolator in for a timer extractor fan.
It will be located in the bathroom do the regs stipulate if it has to be
a switch or a fused or pull cord.

Thanks

Never seen a fused 3 pole pull cord switch.

I just know I need to use a 3.pole switch and wondered if regs dictate
what type in a bathroom.

As far as I know you'll only find one type of 3 pole fan isolator
switch, e.g. something like:
https://www.tlc-direct.co.uk/Products/AA3PSW.html

The regs require appliances (including switches) to be outside zones 0
to 2 (i.e. where they shouldn't get water splashed on them) or to have a
suitable IP rating.

There's no specific insistence on pull cord switches as such though it's
often a way of positioning the actual switch mechanism outside the zones
and keeping the "human interface" conveniently accessible. Also quite
good practice if there's a possibility of it being operated by someone
with wet hands.

The fan isolator is something which will very rarely need to be
accessed. Normally it will only be used when maintaining the fan so not
much problem if it's high up on the wall. It should, however, be
installed where it can be seen by the person servicing the fan.

Thanks that clarifies it for me.

Appliances can be in the Zones, so long as they are suitably IP rated.
For instance, it is very common for a fan to be on the end wall of a
bath.

The Regs do not ask for a 3 pole isolator, they ask for an isolator that
isolates any Line conductors (and neutral on TT systems).
It is manufacturers instructions which ask for a 3 pole isolator, and
that can even be ignored now the 3rd Amendment is here, if you can
justify not having it.
Greenbrook fans do not ask for a 3 pole isolator.

On most new builds you see the bathroom/en suite fan isolator located outside the bathroom above the door so they are convenient to switch from the point of servicing but not convenient to use as the general on/off switch. Most of these fans are then wired into the lighting circuit so they come on when the lights are turned on. If you do not want that and require a seperate switch then if that is going in the bathroom that will have to be a pull cord type and will not need to be a 3 pole type neither will the isolator unless it is being wired through the light circuit.

Never seen a fused 3 pole pull cord switch.

Reminds me of the shower at a former workplace.
High ceiling, and the light and shower pullcords were next to each
other on the ceiling, and someone had the bright idea of having
just one pullcord which split to the two switches about 6" below
them. They were always out of sync whenever I went in there - light
on and shower off, or other way around.

Ok I reckon I have all the info I need now.
Thanks to all for their input.

The general rule for switch gear, is that its appropriate for the
situation and circumstances in which its used. So a rocker switch
mounted high up on a wall in the corner of the room is likely to be fine
if its not going to get splashed etc.

Its not a hard requirement that a switch in a bathroom be a pull cord
type - (although its certainly common to use pull cords).

http://wiki.diyfaq.org.uk/index.php?...trics#Switches

and will not need to
be a 3 pole type neither will the isolator unless it is being wired
through the light circuit.

The three pole requirement does not come as a result of it being wired
from a lighting circuit, but due to it having three live wires (i.e.
line, switched line and neutral).

Don't you mean "line conductors", live, switched live and neutral?

In the complete refurb I did on our en-suite I used the Scolmore Click
Mini Grid modules on a 12-way back plate; it is well outside Zone 2.

I accommodated the fan isolator and fuse, centre light switch, over
cabinet light switch, towel rail switch and indicator light, shower
pump switch and shaver socket isolator using all 12 positions in one
way or another ... got rid of three 'wrong' switches from inside zone
2 plus three horrible pull switches that were not only ugly but made a
din through the ceiling. Have a look at the comprehensive range he
www.scolmore.com/_pdfs/minigrid.pdf

A good deal on the isolator from UK Electrical Supplies he
http://tinyurl.com/obvsxro they have priced down all the modules.

No I don't...

"Line" is the new replacement term is for what was previously called a
"Phase", and in this instance includes the live and switched live wires
but specifically does not include[1] the neutral.

Neutral is considered a live wire, but not a phase or line wire.

It's not a general rule it is a reg:-)

The word is, as you said "appropriate"

Now do you fancy a challenge?

I got an email from a DIY forum http://www.ultimatehandyman.co.uk the other
day. The email was sent to me (OnlyMe)

It seems impossible that I should have received this email (it was spam).

If I sent you the email and the headers could you shed any light on why I
received the email? Only if you are not busy - it is not that important.
