We've had to replace the single oven and discovered that both single oven and hob were hooked into the same terminal strip which was massively overloaded. We've now installed an induction hob with is plugged in to a plug socket on the isolator switch for the oven. The problem we have now is that the cable coming from the isolator switch isn't long enough to reach the oven anymore and we can't replace the cable without ripping out plaster board and tiles. I'd like to extend the cable using a junction box and a 1 metre length of cable.
It's a 32A fuse on the CU and the oven is rated at 2.5kw/h so using the regs and diversity factor it works out at 11A + 5A (plus change, 16.4A really) for the socket on the isolator. The cable coming from the isolator appears to be 4mm stranded flex cable rather than the 7 solid core cable.
My question is, can I just attach a junction box onto the cable and run another cable to the oven. Do I need to find another 4mm cable or would 6mm do it? Does it need to be stranded or can I used solid core?
Hopefully that all makes sense.
