Dual range cooker

[cdisney]

Hi all

After a little help please, as just completed my NVQ and AM2 and not completely confident in everything as I have only done one domestic job in my 4 year apprenticeship.
My neighbour has purchased a dual range cooker (7.4kW) and has asked if I can fit. After having a look I found this and was wondering if I am correct in what I have said:
They have had an extension and have a sub board with a 40A Rcd main switch feeding 32a mcb-skts and 6a-lights. The mains cable feeding this is 6mm SWA 3core. Obviously the range cooker would need its separate circuit so the board would need to be changed as its only a 4way but the mains cable feed would also need to be changed to at least 10mm SWA?
The neighbours plan was to go straight from the board through a wall which the range will be backed onto and terminated direct. Can't find anything in regs saying you can't terminate direct rather than through a cooker switch but is it best practice to do this?

thanks

Care to expand on exactly what you mean by this? It reads as though you mean put a DP switch in each end of the ring?

I was thinking more along the lines of kitchen sockets being wired as lollipop rings allowing a single double pole isolation at the kitchen entrance.

It was only a tuppenceworth thought after upstairs flats recent fire.

That's exactly what it means/say's, it can't be read any other way!!

Whats that got to do with the fixed electrical installation ? It was the upstairs occupants fault !
LOL next you will want fire stations on all street corners lol

Post #32 by Eng54 is bang on in my opinion. It may indeed be very unlikely for a cooker to need isolating in an emergency, but if it does then I would prefer some housewife didn't have to find the consumer unit, empty the contents of the cupboard under the stairs to get it, and then plunge the house into darkness when she flicks all the MCBs off.

With my Mrs, the smoke alarms have gone off way before anything catches fire.

If no smoke alarm around tea time, it's bugger off down the pub time.

I take it it was not within a normal domestic setting?

a guy lived there if thats what your asking, you dont always need a dp switch.

I understand that you may not always need one. I would say however that 99% of all domestic ovens or hobs should have one installed.
