    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...

    My existing kitchen is being rewired? Would it need to comply with the number of sockets in the OSG in table H7? My kitchen is small. Having 6 double sockets (plus cooker switches etc.) looks stupid and I would struggle to use half of them given. My interpretation is that these are just...
