Currently the oven is fed from 13A switch fuse to a cable outlet plate. I'm moving the hob to be over the oven. This is gas but needs mains for the sparker. Firstly is there any issue with hooking into the oven circuit? I can't find a rating for the hob but imagine it will be a tiny draw. Where can I get a dual 13A cable outlet? I can find lots of 6mm dual outlets but that seems a little heavy duty for 13a flex.
