The cooker should never be connected to a normal kitchen ring main.
> Q1.18 Appendix 15 of BS 7671: 2008 gives advice on ring final circuits and sharing/spreading the load around the circuit. Item (iii) suggests that cookers, ovens and hobs over 2 kW should be on their own dedicated circuit. Why can’t ovens of less than 3 kW be connected to a ring final circuit via a suitable connection point such as a socket-outlet or fused connection unit?
> Appendix 15 is intended to give guidance only. Such connection is not prohibited, provided that no part of the ring final circuit will be overloaded as a result.
> Regulation number(s)
> 433.1.5
So, not forbidden, but if you have new wiring the electrician is going to give the cooker its own circuit.
I'm trying to google a diagram, but I only find a bunch of forum posts that explain. For Neff stuff (the one we have), the connectors are numbered 1, 2, 3, 4 and 5.
1-2-3 would be separate phases in a 3-phase home and joined together for a single phase.
