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

    How is consumption measured ? (proper KVA or just amps ?) could be waveforms/phase thing if the meters are not the same type.

    Any generation equipment connected (solar panels that sort of thing)

    How far out is it - could it be within metering accuracy ?

    just ideas.

    Mike.
