You're welcome. As you will have seen, I've just done it as well, but in my case I have nothing other than the connection between my brain and typing fingers to blame
Not without an FCU (because I guess we would have to assume that the hood could create an overload). Replacing the switch with a socket and feeding to the hood from that via an FCU would presumably be OK?
Just about, I suppose. The existing 'cooker switch' actually includes a (not RCD-protected) socket. One presumably could replace that accessory with a similar one (again including a socket) without invoking a need to add RCD protection. You are therefore saying that replacing the existing single socket with a double one would create the need for RCD protection, which I suppose might be strictly correct, even if it does not make a lot of sense! Shifting the cooker circuit onto the RCD side of the CU (there appears to be a spare way available) would obviously solve that problem.
If that was "for starters", is there anything else which you feel means it 'cannot be done'?
If it is deemed necessary to have an emergency switch then there should be one.
I think it is but you can argue it is not.
If it is not deemed necessary then I suppose you may design a circuit with sockets, oven and hob.
However, I do not think it wise to advise DIYers to replace the cooker switch with a double socket.
There is no requirement for an isolator. ... If it is deemed necessary to have an emergency switch then there should be one. ... I think it is but you can argue it is not.
The isolator/switch distinction is really artificial, since any of the switches we would be talking about would qualify as 'isolators'. I would personally certainly want some sort of switch, and so probably would MIs, but I am not at all sure that ther is a regulatory requirement.
It was the OP who proposed/suggested that, not any of 'us'. The OP should certainly be made aware of the possible issue with not having an 'emergency switch' but if he nevertheless decided that he was happy without one, then I think it's reasonable for us to tell him whether what he proposed was, or was not, acceptable electrically, isn't it?
