jl-heating   10 #13 Posted November 23, 2008 i would go for the boiler i have had an earth fault quite a few times on the pump that can cause the trip to go, not enough of a fault to blow a fuse but with an rcd protecting the circuit it will trip it every time.  disconnect for the downstairs circuit replace the power to the boiler with a long lead and plug it in upstairs or take the heating circuit to its own trip on the board and alter the type of rcd ie: try an Type S for a slower trip and still keep the 30mA required trip. bit of info here that might draw light on the subject for you. http://www.diynot.com/forums/viewtopic.php?t=196  or you could find the fault and fix it .

iansheff   88 #16 Posted November 23, 2008 You have not had any floor boards up or nailed anything down have you? I once went to a house where every so often the circuit would trip, the joiner had nailed into a cable putting the board down but it only tripped when someone walked on the board pushing it down that little bit extra. Also you have no flexes running under a carpet or anything? I went to a pub where their circuit kept going, they had a flex under the carpet that tripped as soon as it was walked on Share this post Link to post Share on other sites Share this content via...
