Taking the Ph too CPC as:
Ph cpc
1.0mm 1 mm2
1.5mm 1 mm2
2.5mm 1.5 mm2
4.0mm 1.5 mm2
6.0mm 2.5 mm2
10mm 4 mm2
16mm 6 mm2
Why suddenly do we need a 4mm CPC for a lighting circuit taking into account that the CPC in T&E is only single insulated by way of the sheath and can be run inside a stud wall without any additional protection, seems a bit of a nonsense to me.
