I stuggle with this. When a light blows here it takes out the circuit
trip
but has never to my knowledge tripped our 30mA RCD. Is there something
system dependent here ?


My 'reading' and I'll admit it's not personal experince is that some
lights, such as Floureseents can have leakage which can cause a 30mA trip
to
activate ... whether this is on switch on , or when choke gets hot, I'm
not
sure.

Possibly. But I've done same as Tony and put everything on a pair of 30mA
RCD CUs.
