Re: H05VV-F Power Flex
Hi
Your oven has a 5.7 kw total load. The flex Neff quote in the instructions should be H05VV5-F-3G-006 which goes to a 4mm flex like 4.0mm 3183TQ Butyl Flex which is also heat resistant.
You will probably struggle to find it readily available in a short length. Easiest way is to get some 6mm twin and earth cable which is standard freestanding cooker cable normally available from most DIY chains and electrical shops.
HTH 🙂
