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

    Whilst not answering your question, in cases where there is concern over sub metering, I advise the occupier to switch off their main switch to see if any other users (including communal lighting etc) suddenly loose power! Obviously be mindful of your freezers, fish tanks and anyone on life support!

    This applies to cases where usage is higher than expected, not your strange situation. I can only suggest that as has been mentioned, the quality of the sub meter.

    I've got one to resolve for a client (although to me the answer is obvious) in as much as he supplies converted “cookers traditionally found in farmhouses” to electric. Needless to say a purchaser has complained about the £200 a month increase in their electricity bill…..

    I'm not sure what the purchaser expected his bill to be……..
