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

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

Is anyone else suprised that some sparks here woukd NOT install an DP swirch for a cooker/hob supply?

 

[Leesparkykent]

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.

Have you stocked up with 1000s of metal CUs yet, so you can get all your customers installations up to 17th Amd 3 conformity?

I cannot say for sure right now but I would put money on there being one.

No. We do not do domestic works so this will not effect us at all. No money in the dometic game for us.

My 12 year old calls the smoke alarm, "the sausage indicator", with no small degree of accuracy...:ack2:

That depends on where this commando plug and socket has been located. If it's stuck at the back of a cabinet full of pots & pans or tinned foods, like a lot of todays so-called designer minimalist kitchens, and it's not going to be of much use to anyone if needed to be got at quickly!!.

hang this on a nail by the cooker.


isolates the cooker and also locates the OCPD.
