is it acceptable to have kitchen appliances on a radial circuit?

1. You can’t spur off with 2.5 off of 4mm as if it’s a 32 amp it’s higher than the current carrying capacity of 2.5 mm. 2. What sort of protective device are you using? 3. Hope you have an RCD backing all this up? 4. Why are you using j/bs under the kitchen cabinets? 5. Keep the cables away from the insulation as it de rates the cables. 6. Why don’t you use a ring circuit? That way it’s all 2.5 same size mcb. 7. Why not get a registered electrician to design, install, and most importantly test this issue you a certificate. Get any of the afore mentioned points wrong and god forbid something happens due to what you have done I.e. a diy job, your house insurance is null and void. Hope this answers your points.

I cannot stress enough how electrics is not for DIY enthusiasts. Its a life and death situation if anything goes wrong; which you most definitely would be prosecuted. Don't mean to offend or undermine in any way, just intent on safeguarding human life. I'd definitely recommend getting a qualified electrician in to give you the advice you need. Thanks
