DPC PUBLISHED FOR 18TH EDITION AMD 3

John Peckham

I had an email this morning from the IET telling me that a Draft for Public Consultation has been published for Amendment 3 to BS 7671.

  • Will this be classed as a C1 or C2 on an EICR if a Unidirectional is fitted rather than a Bi-Direction if it is fitted to Micro-Generation like a Car2Grid or when doing PV to Grid?  Also would it require a replacement breaker as the wording in the proposed Regulation states SHALL?  

    Or maybe just a C3, or NOTE? I don't think the SHALL word is that significant - 514.4.4 says shall for colour coding, but I don't think anyone's ever suggested we need to rip out all the red & black cables and replace them with brown & blue, or even code them C1 or C2 just because of their colour.

    Hi Andy

    Can I play devils advocate??

    Regulation 12(1)(b) of EAWR states ‘where necessary to prevent danger, suitable means shall be available for […] the isolation of any electrical equipment’, where ‘isolation’ means the disconnection and separation of the electrical equipment from every source in such a way that the disconnection and separation is secure.

    Key Part

    disconnection and separation of the electrical equipment from every source
