Interesting to know about fluctuating readings for RCBOs did not know that and certainly useful to remember, if one forgets to disconnect.
I have heard anecdotal evidence that suggests that sometimes RCDs do not work after an IR test so I have always not tested through them, but I may relax a bit now (especially for crabtree ones).
