Separate oven and hob on existing 32A cooker ring

[itk2012]

Hi everyone,

I need to replace an old cooker with a separate double oven and induction hob, the current cooker ring is connected to a 32A rccb.

The old cooker is rated at 10.6kw, the oven and hob together are 11.4kw. With the diversity calculation it comes out at 21.25A (unless I'm an idiot), so would it be ok to connect these two appliances to this ring even though the potential maximum load would be 47.5A (not that I'd ever switch on everything to max all at the same time).

Assuming this is no problem how would you split the wiring to the two appliances? Run a cable from the isolator switch to a junction box, and then two cables to the individual appliances?

1. It will be fine
2. It is almost certainly not a ring but a radial

Your understanding of diversity is good. Crack on

Shame lots of so called sparks can’t do this

Perfect, thank you. Yes you are right, it is a radial!
