Hi, im just after a bit of advice please,im just about to rip out and fit a new kitchen,i`ve bought a new electric double oven and electric hob,i have a cooker socket with a 10mm cable,the instulation book for the cooker says to use a 2.5mm cable and the hob is 6mm cable.What i want to do is fit the cooker next to the cooker socket and the hob on a sort of island unit in the middle of the room so what i want to know is would it be safe to run a 6mm cable behind the back of the kichen units to the hob? ,it would probably need about 4 metres of cable to do this although the hob would still only be about 2 metres from the cooker socket , any advice anyone cheers.
