Have you **unplugged** all appliances to be certain one of them is not
responsible.

Disaster has struck. For no apparent reason the RCD on my MK Senrty CU
has
tripped. I cannot get it to reset which suggests to me that either a)
the
DCD is knackered or b) there is a fault on the fixed wiring. I've
tripped
all the MCB's to try to isolate the circuit with the fault but this
has
not
helped as even with all the MCB's to off the RCD will ot reset. Nobody
in
the house was using/doing anything out of the ordinary when it
tripped.
House was rewired 9 years ago.Any ideas ?
