Hello. I am trying to decide where to position my 2 burner induction hob. Either it goes directly in the middle of the oven and therefore 300mm from the isolation socket and 120mm from the sink edge. Or across to the left of the oven and 200mm from the isolation socket and 300mm from sink. My electrician has said that the hob need to be a minimium of 300mm from socket but no distance is specified from the sink.
