db/cu and 521.5.1 Ferromagnetic enclosures: electromagnetic effects

a good day wishes to all

 

‘they’ do not write these things for no reason; there is science present, so …

using this example: what's the non-compliance issue, if any in reality, with meter tails entering a db/cu through the same opening (fair enough), but a main earthing conductor being glanded/bolted to the housing inside (via a different aperture to the tails, to the earthbar attached to the case, along with bonding etc),  or even on the outside  ?

    Good, that is that sorted. Are we all agreed that a non-compliance is C3 rather than C2?

    So now what about a MPBC? As far as I can see, that is allowed to go through a hole of its own.

    No, a non-compliance is a non-conformity that would give rise to danger. In this post my interpretation would be that the situation would be a non-conformity only. Personally I would not mention on any report.
