sub-DB reading higher than feeder DB

Former Community Member

Hi,  I have a main distribution board which feeds into a sub-distribution board.  This sub board then feeds into two buildings.  Via a cable into the one building and also via a cable into another distribution board in the second building. What is puzzling me is that the distribution board in the second building shows a higher consumption than the main board which supplies it.  Does anyone have an idea how this could be possible? Thanks very much, Nick

    Picking up on the comments by @mapj1 if there’s PV on the roof it is possible the upfront meter could run backwards, so the landlord could be on a winner with whoever pays the bill based on the second meter paying more than the bill for the first meter.
