Hi Guys
New to forum and enjoying reading the threads, all interesting, so..
Looking to re-wire my kitchen due to re-fit and some of you will be unhappy (understandibly) as I am not a qualified sparky, but I will notify building control and get the work certified and passed. This is simply an interest of mine and I enjoy it, I certainly don't intend killing myself or anyone else in the process and will get in local authorities for cert...so here goes, lot's of reading, bear with me, as I really can do with the help to clarify if I am wrong alltogether or on the right track being a diy'er.

I am now installing at home a built in oven 3.39kW, microwave 900w, induction hob 7.5kW, Fridgefreezer, under counter freezer, washing machine and Cooker hood 250w.

All appliances with 4 meters of DB and Clipped direct to wall behind open cavity, not insulated, 75mm cavity to address 50mm depth regs, don't intend to mechanically protect wiring, due to 75mm deep and RCD protected. Walls plasterboard lined for convenience, all wiring within prescribed zones!

So, would this be correct for regs... I have a
Wylex,14way Split Load DB, 2x 80A/30ma RCD's with the addition of potential seperated RCBO's below:

Oven and Induction Hob - DB 32A RCBO
Appliance's Total = 10.89kW- 47.34A using diversity and if maths correct:-
30% = 11.2A, 11.2A+10A= 21.2A total, so from DB using 6mm cable via 45A CCU down to Dual Cooker Outlet using 6mm cable, seperated and terminated at both appliance's using 6mm cable.

Fridgefreezer and Freezer - on separate 20A RCBO dedicated radials using 2.5mm cable via Switched FCU's down to flex outlet plates.

Washing Machine - I'm sure read somewhere regarding Nusiance tripping, not sure if 17th Edition about putting the likes of the washing machine again, on a dedicated curcuit, 20A RCBO using the usual method mentioned or, I could spur off rfc with Switched FCU down to flex outlet plate. This was when I was told I was over the top and pointless by a Sparky, always learning, even at 50.

Finally Microwave(900watt) and Hood(250watt) total 5A
Could these both appliances be powered via a junction box to separate FCU's and outlet plates, on 10A RCBO dedicated radial curcuit.

I have room for these dedicated radials and can keep the RCD protected Split Loads seperate, would this then be the making of a High Integrity Unit?
DP RCBO's or SP RCBO's, so many views on this, not sure.

If you have read this far, I commend you for your patients and appologise if my terminology is not adequate and certainly look forward to your comments and would really appreciate the feedback.
