4 mm Cooker circuit 32amp MCB

[Essex_]

Maybe one or two do learn from a bit of experience...and don't jump in headlong thinking they know it all.

Yes. And I was happy to see that. Fantastic. My other comment was about others not the OP. I think what the OP done was great. I don't understand.

thanks for all your input cleared up a mistaken assumption on my part.

...4mm radial. Your pulling my leg. No such thing.

What do you mean?

I'd have to say thanks too. :stooge_curly:
I've been told it's calculate the design current, select the protective device rating, then the cable ?

You need to read the whole post for it to make sense.

Ah great.
I've had my head in the books a lot of late, I was just checkin' I wasn't getting things mixed up LOL

 

[yellowvanman]

i just thought or assumed that 6mm was the minimum cable size allowed for a hob/oven appears i was wrong

this is historical from when BS3036 fuses were used.

ref 433.1.202

will be fine on 4mm. one reason 6mm is more otfen used is that you're more likely to have some on the van.

As I do, if you ask your wholesaler about 4mm not many stock much and to be honest the price difference isn't that much.

Assuming your customer is replacing their 2.3kw oven with a new 7.3kw hob - why not get the installation instructions of the new 7.3kw oven and see what the manufacturer recommends, if you install anything less than the manufacturer recommends, you are not covering yourself.

Diversity for stats kicking in and out is great but tell my wife that she will never have all the hobs and ovens on at once lol

I for one always allow for the worse that way we are always covered also we also are having more and more split ovens (2No) and hobs in a lot of installs, these ovens require being fed via separate radials as the ovens my be 20/32amps and the hob only 13amp via a socket not off the cooker circuit.

I'd much prefer to use the 60+ year tried and proved system of cooking appliance diversity, than any manufacturers instructions/recommendations. As stated many times here, for some reason these manufactures work around connected loads, that in many cases, not all of those connected loads can be utilised at once...

I bet there isn't many electric hobs out there that are on a 13A plug top, it's normally the oven that comes with a 13A plug top!! lol!!

Hells bells, what sort of domestic oven would need a 32A supply each??

I'm still trying to work out how 4 X 1.5KW equaling 6KW (using the lowest stated elements size) suddenly becomes 3KW suitable for connection via a 13A plug top, unless i'm completely missing something that is?? lol!!

Is that for two ovens or one oven??
