Caravan RCD trip power connections

Paul R
Dear all , a holiday question


I have an acquaintance who asks why his IET 18th Edition RCD tester when plugs it in to the Local RCD (<30mA/300mS) , the primary supply RCD trips (that is further up the AC supply line) , rather than the caravan’s, so in effect nullifying the test.

Is this because the Primary Supply RCD  is monitoring a small standing current from other connections and the Local RCD needs to be tested by using the Local Earth at the unit ? ( which is not so easily accessible). 


Are there any other thoughts please ?

    Still too expensive ... try this getup:


    A fixed 16 A BS EN 60309-2 splitter plus a 16 A BS EN 60309-2 plug to BS 1363-2 free socket-outlet.


    We're now at < £20 with no kit mods to do the job far more safely, which I think is the right ballpark.


    I agree about the price - it was just the concept I was trying to sell as it were. I did first think of the 16A splitter - but though it unlikely they'd fit into a caravan's inlet without fouling the bodywork so requiring extra 16A leads - hence thought the Y-shaped flex approach might be better. There are cheaper ones elsewhere of course. Or even make up one from standard parts - with a longer leg for the 13A socket so it could directly reach into the caravan near to a suitable socket for the test, which might be convenient.

    I was thinking the splitter would fit in the pitch socket, you will need a spare extension lead either 16 amp or 13 amp either way.

    Or wander lead.
