Okay how about a 4 pole RCD located to the side of the CUs and a 4 pole isolator located near the hob?

sledgehammer and nut comes to mind.
 
I give up if you cannot give a sensible answer why bother at all!!!


I apologise for my post, but you have been given the most sensible answer a while ago - you need an electrician.
 
IT'S A BLOODY HOB, ffs. NOT A DOCKSIDE CRANE. JUST INSTALL A SINGLE PHASE 32a CIRCUIT USING 6.0MM CABLE
 
Diversity , you have never seen my missus cooking. The hob has a total of nearly 16kw of cooking area but the load is limited by the hob to 11kw so the total current could be around 50A so a 32A circuit not exactly ideal. Hence my wanting to spread it over 3 phases.
 
I've never seen someone with a negative reaction score. I feel a bit sorry for him:(
Write something sensible or at least funny @Bogart and we can maybe get you into positive territory :)
 
Attached is a photo of my setup. I have been asking questions on another forum but keep going around in circles. The hob has a combined load of some 15kw but limits itself to 11kw ie around 50 Amps. Yes diversity is a factor but there is a possibility that it could draw 50 amps and I think that is a lot of load to put on one of the CUs, hence my 3 phase query.
So how about I install a 3 phase RCBO coming from the Henley blocks and a 3 phase isolator near the hob?

i'd start by removing approx 16 unnecessary yellow stickers.
 
I will help you as a diyer with small like for like appliance swaps or adding a spur. Things like that.

But,
You are into the realms of designing a new circuit and dealing with 3 phase.

This is beyond DIY.
 
By the looks of it you’ve got 10 circuits spread over 3 boards?......(you could probably do the lot on one board realistically if you did some calculations) why not just re-jig them slightly and feed the hob from 1 new rcbo.....50a if you feel the need but I doubt you’ll need it.
But bare in mind it is notifiable work so you’ll need a spark in a scheme :)
 
" bear", "bare" is naked, just a push from the spelling gestapo.
 
I thought @Pete999 ran that department :tearsofjoy:
as pirate will tell us, always bear to windward of the enemy. that way, when you set him on fire, it won't fry your sails.

Wise words......I’ll remember that next time I go buccaneering :tearsofjoy:
