I am not qualified electrition but have good diy knowledge.Can someone tell me how can i connect an electric oven .Can i take a spur out of ringmain as a socket and plug oven into it or is it better to use fuse connection unit. if so what rating fuse should be used.In instlation book it says min fuse 15amps-20amps and cable size min 2.5(what does it mean),or is it better to run 2.5 cable directly from consumer unit (from 32 amps fuse) as a double pole socket and plug oven into it.Thank you.
