   Interestingly, the NICEIC helpdesk called me back and refered to the OSG page 41 (green) and the top line reads something like 'For PME systems the DNO may require the Earthing Conductor to be 16mm'
   
   Voila, so if the DNO are happy with a calculated EC then its okay.

   Interestingly, the first known use of 'voila' was in 1739

   Still needs to be a minimum of 10mm² to comply with BS7671.
