  • PMS? Did you mean PME?

    10mm² as a earthing condutor might be OK - it all depends on the details of the situation - table 54.8 would be satisfied provided the PEN conductor is not larger than 35mm² so then you're looking at the adiabatic, PFC and fuse rating/type to decide if it's OK as a c.p.c.
