Is it ok to run cable within a boxed vent pipe?

[magicstu]

I may get my head bitten off for this, but please be nice. I want to get the supply to my cooker replaced from 6mm to 10mm, but the existing route is almost impossible, but there is an easier route following the vent/stench pipe (that is boxed in ) through the bathroom and into the loft, then across to the front of the house and back down to the consumer unit. One company said they cant do it, as it passes through the bathroom, another has said it's ok because the cable is not part of the bathroom, and the boxed corner is completely built into the wall, I want to run the cable myself and get the electrician to do the final burying of the cable in the kitchen wall for the last 1.5 metres, and the final installation at the consumer unit with a new breaker, neither have an issue with that, its just the cable running down the boxed in pipework- Can anyone tell me if there are any regulations that it breaches? Thanks

Trust me, the big wolf ranges draw the full whack in self cleaning mode! They are big old beasts though, look like commercial cookers adapted to go in a house.
One of the ones we had was 1800 wide FFS!

I don't disbelieve you, but they would have to be way over 15KW, if this range cooker draws 50A in self cleaning mode. After all, the hob elements aren't going to be drawing any current at all, in self cleaning mode!! ....And that's a hell of a big chunk of the units KW rating taken out of the equation!!

Pure nonsense for a cooker of this size to be installed in a domestic setting anyway, unless of course you're cooking for the areas Meals on Wheels!! lol!!

Have you any idea how many Chinese families can be squeezed into one two bed upstairs flat??

That'll be no problem, most Chinese cooking is either very fast high heat cooking, or very slow low heat cooking!! And they only eat a little, but often!! lol!! What's more you'd have a hard job finding a Chinese home over here with a cooker in the kitchen, they will just have a two ring gas or electric worktop affair and maybe, if lucky a worktop oven!! Microwaves are getting common now, but again only the small ones, not the bigger combo units you see in the UK etc!!


Afraid you picked on the wrong race to warrant an oversized domestic cooking range!! lol!!

I think 6mm cable is fine for handling this issue. I recommend to first contact any registered electrician you trust and let them do this job.I have seen this in most older houses, they used this type of settings.

Some time back I rewired a domestic range installed by another company on a 32a/6.0 which continually tripped the mcb whilst cooking christmas dinner,put it on a 10.0/50a and it's done several chrismas dinners since..

if the 6.0mm was method C, i'd have no hesitation in upping the MCB to 40A.

,,,, nope, after all the comments, going to fit the oven and see if it trips, as the friend who had the issues lived in an old house and maybe didn't have 6mm cable- thought it was a simple question of can I run the pipe through the boxing myself to save money(lost my job halfway through taking kitchen to bits), but if it needs replacing because it trips, I will just get the guy in who said it was ok and let him do the lot, Thanks for the time and info on this one, really appreciate it.
