things like today make me want to go all cicruits on rcbos
if only people wanted to pay the extra!!
1) the RCDs dont work with the circuit connectedSo leaving the circuit unsafe is a better option is it? At least the RCD is present and can be tested and certified as such.
1) the RCDs dont work with the circuit connected
2) whoos to say that just putting the offending circuit on an RCBO will give THAT circuit additional protection?....the RCBO may not work due to THAT circuit being fed from it....so how does that comply?!!
Well I was wondering what the next 18th might ask for.............. !

i tested at various points throughout the house and the result was always the same with the lighting circuit connected they wont trip.
as you say i know that memshield 2 rcbos wont trip properly up close
Does the "errant" RCD fail to trip at BOTH 0deg and 180deg with the suspect lighting circuit connected?
I suspect it's what Des was alluding to earlier with DC saturation. That would only affect one side of the waveform. If it works on one half but not the other then I'd suspect a combination of what Des and spark1973 (possible faulty dimmer/wiring issue (to explain the poor IR)) said earlier.ah interesting
have to say ran auto test so fail at 0deg didnt try 180
however did try x5 manual 0deg
why do you ask

Edit: In case that's not clear it would need to be a faulty dimmer/switch and the wiring fault (to allow DC from a transformer into the circuit).
