Neutral to earth on genny

Can I ask your opinion in relation to neutral /earth on this rather untidy changeover arrangement located just downstream of the main isolator? There are 2no 3-pole contractors with mains in bottom left and generator in bottom right. On the stud adjacent they have connected gen neutral, DNO neutral and installation earth. The arrangement means a self-imposed conversion to an unauthorised TNCS. I can’t be sure if the existing supply is already TNCS.

  • Shows you how subjective these EICRs are. Here we have one top man on this forum saying “it’s probably not that dangerous” and another who is prepared to serve a Danger Notice. 

    perhaps Alan would be kind enough to expand on the dangers as he sees them?

    David, WB, I cannot give a C2 or FI as the report must have a satisfactory designation so such things must be rectified before the issue of the report. I have a list of other things that fall into the C2 category for this particular installation. However, it seems to me that any given code should be accompanied by a clear indication of the reasons the call has been made along with a reference to at least the most pertinent regulation that has been breached.
