Kitchen Electric / Oven Isolation switches

[wozza]

Hi All,

 

We are currently planning our new kitchen and are coming close to ordering it. I have a few questions regarding the electrics so I can be pre educated before I speak to the electrician and kitchen fitter.

 

The two ovens that we are having will be in the middle of a bank of four tall larder units. The supply cables are fed to the approximate location of the ovens and each oven has its own MCB in the CU.

The only place that we can fit isolator switches is inside the larder units, either to the side, above or below the ovens.

 

Do we legally have to have isolator switches? If not is it good practice to have them even if not visible or easy to get straight to? - the CU is in the adjacent room and each oven can be isolated individually as each oven is wired individually to its own MCB. If putting switches into the cupboards should they be recessed or surface mounted?

 

Also in our old Kitchen the Dishwasher lead / plug was fed through a hole into the adjacent cabinet  - it was then plugged into a switchless socket that was surface mounted in the cabinet - the supply to this socket was then fed from a flex outlet on the wall behind, that was then fed from an isolator switch above- is that the correct way to do it? 

 

Many Thanks, Wozza.

Ovens and hobs should have isolation switches. They just need to be easily accessible for maintenance purposes.

Surface mount is fine.

Dishwasher into a socket (either switched or unswitched is ok), surface mount is ok. Socket should really be part of the ring main or could be a spur from another socket on the ring

You could argue that the isolation switch is already provided by the big red isolator in the consumer unit and nothing else is required.

Normally even the dishwasher socket has an isolator switch above the worktop.

 

Does the room with the CU back onto the kitchen? How about isolators there?

Yeah room with the CU backs onto the Kitchen, the cables have already been fitted and plastered over so it would be a lot of work to do and the switches would be above or next to the CU.

 

Will have to put the isolators in the cupboards then.
