    Understanding minimum CPC requirements?

    My assessor said that the minimum CSA for a Main earthing conductor for a TT was 16mm. I questioned this as I thought it was 4mm. Regulation 542.3.1 states every earthing conductor shall comply with section 543. Section 543 refers mainly to the adiabatic (reg 543.1.3) or reg 543.1.4 (table...
