Cooker isolator location

[Penance]

Been looking at the OSG to part p and not sure if I have this right.
There is a diagram showing a minimum distance from edge of cooker to the isolating switch of 300mm but I can't find any other reference to this.

Am I right in thinking that the isolator does have to be a min of 300mm away and not more than 2000mm away from the edge of the cooker?

Am I missing something here, part p OSG says 300mm, so where does the 150mm come from?

150mm is just the standard measurement we all use on all our sites for over 5 years, this didnt even come up on my 16th edition

Well I did the 15th and don't remember the 300 mentioned.

Thought it was a part p thing not regs?

just found this >>
There is no distance stated in BS 7671 however it is the view of the NICEIC that socket-outlets cannot be closer tham 300mm from the sink or draining board.
or
The IEE’s Electricians guide to the building regulations sub section 5.2.2 Locations of accessories in kitchens states;
(iv) Accessories should be installed a minimum of 300mm from the edge of kitchen sinks and draining boards to reduce the risk of being splashed.
AND

Positioning
The switch or control unit should be readily accessible. It should
not be positioned behind or above a cooking appliance such that
a person would have to reach over the appliance in order to
access the switch/control unit.
The horizontal distance between a cooker switch/control unit and
the appliance(s) it serves must be sufficiently short for the switch
to be under the control of persons relying on it for safety. This
requirement is likely to be met if the distance does not exceed
2m.
The height of a cooker switch or control unit in an installation in
a new dwelling should be suitable to facilitate access by persons
in wheelchairs and others whose reach is limited (as should the
heights of all wall-mounted switches and socket-outlets). Based
on the recommendations of Approved Document M, applicable
for new dwellings in England and Wales, the height of the switch
or control unit should not exceed 1.2 m above finished floor
level.
Installation of a cooker switch or control unit in a cupboard or
cabinet is not recommended. Potential users of the
switch/control unit may not be aware that it is there, or items
stored in the cupboard may obstruct access to the switch/control
unit. In any event, wiring and other electrical equipment should
generally not be fixed to a cupboard or cabinet, which may be
removed in the future; they should be fixed to the building fabric.
It is also not recommended to locate a cooker switch or control
unit in a central wall-mounted control panel together with other
switching devices, as this may result in the switch not being
under the control of persons relying on it for safety or otherwise
not being suitably accessible. Where a cooker switch or control
unit is positioned in such a central control panel, then, as for any
other item of switchgear or controlgear, a label or other suitable
means of identification must be provided to indicate the purpose
of a cooker switch/control unit, except where there is no
possibility of confusion (Regulation 514-01-01 refers).

seems as there is no actual regulation on this so thats why we use 150mm minimum !!!
the 300mm rule is from the sink only and applies to all sockets and spurs and obviously the cooker switch
so if cooker near a sink then locate to far side of cooker away from the sink so 150mm minimum is required - always use the best side of cooker !![away from sink] hope this helps !!

Thanks, in the OSG to building regs there is a diagram that shows the cooker to isolator distance as 300 but nothing in writing.

Nice of them to make this clear!
