    Guys.
    I've a new house that the kitchen space was for a double oven and has one cooker wire coming in, however we went for a single oven and a combi microwave on top. Am I good to wire both to the one wire and will I need a junction box to split it into both?
    It has the regular isolating switch in the kitchen
    Any help appreciated.
    Thanks

    You can purchase a cooker switch with a built in 13A socket.

    If you read the manual for the oven, it will more than likely recommend that it is supplied from a 16A MCB, so that would be the first thing to check. Every oven i've seen connected has been connected to the "cooker" supply in the kitchen, normally off a 32A MCB, with no RCD. The issue is that there is little protection for the cables supplying the appliances after they are split out from the 6sq supply cable. Now as these appliances are a fixed maximum load, in theory the cable should never be over-loaded.

    I presume your combi microwave is a built in appliance and as such wouldn't need RCD protection, but others here would need to confirm that. I would probably fit a socket to the end of the fixed cable and use this to supply the microwave, then take some heat resistant flex down to the oven from the rear of the socket. The socket should be marked for fixed appliance only, no RCD.

    BTW what are the individual ratting of the oven and microwave? ( i would guess a combi microwave might be quite high?)

    Thanks guys.
    Both manuals read the same. 230-240v supply 2.5m2 cable and Min 15a and max 25a fuse. The MCB is 32a on fuse board so should be ok. The combi has the small flex at the back no plug however looks ready to wire into a plug (small cable) will I just stick a plug on it and stick a double adaptor on the fridge socket and plug it in? Don't like the idea of power going to it all the time.

    Alternative is I have regular round junction box could connect this with the 6m2 cable and small combi cable and feed a 6m2 cable off it to the oven?

    Thanks in advance
