Hello there,

I'm currently planning the cable runs for our new kitchen extension, as
the plasterer is here on Monday!!

I have explained to SWMBO that I need to know where the Dishwasher,
Washing Machine, Dryer, Fridge, Freezer are to be located to allow me
to place the switches above worktop height to isolate the behind
cupboard sockets


The remote switching for these low level un-switched sockets can all be done
from one point. The sockets can be run on radial wiring to the exact
positions for the appliances from there.

The sockets should really be un-switched to denote they are remotely
switched though, and the isolator switches should be double breakers to make
them safer.

SWMBO isn't impressed with having these switches above the worktop...

As I have plenty of spare ways in the consumer board, (I have installed
2 * 12way split MK boards) can I run a single radial 2.5mm cable to
each outlet and use the MCB as a means of isolation on the rare
occasion it is required?

If I need the isolating switches, can I supply double socket rather
than single outlets?


The best method is to have the isolator switch break both poles to the
circuit, which an MCB doesn't do.

I've never heard of any problems having a two gang socket fitted to the one
remote switch, but they socket does need to be un-switched to mark it as
having remote isolation switching on it.



Secondly, but on the same vein,

We have a duel fuel , gas / electric range cooker which needs a supply.
I intended running a 6MM^2 to a outlet behind the cooker. Do I need an
above worktop switch? Can it be inside a cupboard? Can I use the MCB
as a means of isolation?


You really do need at least a double pole breaker switch near at hand in
case of emergencies, and for convenient use of isolation by a maintenance
engineer.

The use of double pole isolation means the appliance can be worked on
without the neutral conductor still having some capability to cause a shock.
So an MCB isn't really a good method of totally safe isolation because it
only breaks the Live supply side of the circuit.


Many thanks for any help.

(just on the way to waterstones to collect on-site guide to the regs)


p.s. (sorry about this)
can I run cable horizontally between above worktop sockets?


If you intend to drill through the walls to install hanging racks and
things, then it isn't a really good idea to have long horizontal cable runs
around the kitchen walls. This is especially so if you sell the house on,
and the new owner has racks to hang on the walls.


How close to the sink can electric sockets be?


The socket can actually be in the sink if it is designed for the job, but
the best rule of thumb is "Not in a position that can be easily splashed
with copious amount of water from the sink".
