I think the first electrician doesn't know about diversity in cooking appliances. And the second shouldn't be suggesting to wait until things trip.
they should confirm that on site in accordance with the regs
Hi bigspark17, to get the new cables would require either unsightly trunking along the entire length of the hall way or taking up the new carpet/chipboard upstairs to hide the cables. Neither ideal tbh. This is why I came on here to get a second opinion. It would seem that everyone has a different opinionThink the comments are slightly unfair as no member has seen the job. If its only 3m away how hard isit going to be to wire 2x radial circuits to the ovens and put 20A dp switch above in the cupboard (assuming its larder unit). Could be easier/cheaper than faffing around with the old 6mm supply, and yes diversity proves it could take it but there is the chance you could overload it and guidance is for any fixed load appliance >2kw to be on a dedicated circuit.
Just saying
The regs are concerned about safety, not standardisation, so there's more than one way to skin a cat. Design involves more than pulling a standard circuit out of your back pocket, you have to look at what's there and make a suitable design for the situation in front of you.It would seem that everyone has a different opinion
I’ve seen that before shower piggy backed from cooker switch how the hell they fitted two 6mms in I’ll never know none of them even had cores chopped to fit I got the call because the cooker isolator smelled like fish when the shower was onjust as an aside, i recently came across an installation where a 6.0mm cable on a 30A 3036 fuse had happily been supplying a sub-main feeding a free standing cooker and a 8.5kW shower. been fine for over 30 years. no sign of cable damage.
Especially with two lots of mushy peas14.5KW on a 45A OCPD?
Diversity is one thing, but surely there must be a (considerably) greater than zero chance of everything being turned on all at once from time to time?
One only has to imagine Christmas dinner with a few of the relis to see how.
Even though the oven with the bird and the pigs-in-blankets in it will likely be up to temperature and thus only clicking in and out relatively infrequently as the crisis peak approaches just before the critical moment when dinner is ready to be served there are still going to be times when this will happen when you have the plates, stuffing, parsnips, beef (for those weirdos in the family that don't like turkey), and the roasties keeping warm in the second oven, and then the hob rings are being used to cook the carrots, peas (for those weirdos in the family that don't like mushy peas), sprouts (which have been on since the 1st of November just to make sure that they are properly cooked), mushy peas, cauliflower cheese (my sister-in-law does a stunning Christmas lunch but this is just plain weird of her), whilst the bread sauce (s-i-l weirdness again! ) and Xmas pud are slowly simmering away at the back.
I mean surely, this has got to test the endurance of the poor old 45A OCPD hasn't it?
