Hi all

Can anyone advise me on cable size for new cookers please?

Currently there is a 6mm feed for a distance of about 20m from CU to wall
point.
This serves a Creda double oven and separate hob (both to be replaced during
kitchen refurb).
The feed includes a junction box from the time of the kitchen extension
addition.
By re-routing the first "leg", I believe I can reduce the distance to the
junction box to about 12m.
I then intended to put a more substantial jb at that point and run separate
6mm feeds to oven and hob.
The initial 12m run is located in the first floor ceiling and grouped with
the main "wiring loom" for power, lighting etc.
The jb and two separate feeds will run across loft space above kitchen
extension and then plastered into wall (say 7m max length total each
separate feed).

So the key question is:

With this arrangement, will 6mm from the CU be OK for most modern oven/hob
combinations, or do I need to replace all with 10mm?


TIA

Phil
