I have a 2370W oven that need to be installed. The problem is that the location of it is far from the consumer unit and the previous owners had not installed a 30 Amp ring for the previous oven (also small). I have litle chance of creating a 30 Amp ring and was wondering if instead I could take a spur off the kitchen ring (comprising 4 double sockets only) to a Switched 13 Amp Fused Connection Unit. The Maximum wattage of which is 3000W. Is this at all safe or am I in danger of setting my house on fire???
