Hi Anthony, Thanks for your input. I am not aware of any law governing the mains cord approval in such product. Could you please shed some light on to me that which law/regulation calls for mains cord approval like mains plugs to be approved by ASTA/BSI/Nemko. As far as I know, mould plugs do have approved cord as a cordset requirements in ASTA/BSI/Nemko approval.
