We currently have a freestanding cooker which is wired with 6mm cable to a 45A mcb, but will soon be installing a separate hob and built under cooker (it is likely that they will either be 30A or 45A rated), and I needed some clarification on the correct mcb and wiring.
We also have a separate 45A cooker switch (with socket) installed with 6mm cable which is not currently connected to the consumer unit.
1) If the new cooker or hob requires 30A protection, can this still be wired to the 45A switch and then connected to the existing 45A mcb, or would the mcb need changing to a smaller one?
2) As the cooker and hob will be separate, can they still both be wired to the same terminal block, and then with a single cable to the cooker switch and mcb?
3) Also as the cooker and hob are separate, does this increase or affect the required protection from the mcb?
4) It states in the wiki here that cooker switches with a socket will require an upgrade of the level of protection. Does this mean that the mcb may need to be higher than 45A and the cable larger than 6mm?
Thanks in advance.
