Mixing 2.5mm twin and cpc with 2.5mm twin and 1.5mm cpc

StephenS147 · 2020-03-13 21:28:40

I've bought some 2.5mm sq twin and CPC from screwfix for extending a radial power circuit. 2.5mm sq is for all 3 conductors. I only realised when it was sent out that the CPC was 2.5mm sq. The existing is 2.5mm sq LINE and NEUTRAL with a 1.5mm CPC. Is there a problem mixing the size of the CPC?

Sufficiently low earth fault loop imperial is what matters.
