apologies if you are already aware of this but with respect to the x5 or greater test current introduced in the 18th, Hager have advised that their RCBO units are manufactured to the 2017 amended version of BSEN61008/9 which permitted disconnection within 40ms at 250mA. Thus they advise testing at x 5 on both sides with the instrument set for 50mA on the variable range.
The verification of the effectiveness of the measures applied for additional protection is fulfilled by visual inspection
and testing. Where RCDs are required for additional protection, the effectiveness of automatic disconnection of
supply by RCDs shall be verified using suitable test equipment according to BS EN 61557-6 (see Regulation
643 .I) to confirm that the relevant requirements of Chapter 41 are met. NOTE: Effectiveness is deemed to have been verified where an RCD meeting the requirements of Regulation 415.1.1 disconnects within 40 ms when testedat a current equal to or higher than five times its rated residual operating
current
My bold in the italics - now to me, and maybe to others, this says 'it is OK not to bother to check at the 30mA rating' Anything more than 5 times that would count as a pass, in principle even a test at many amps. ' That is an implication that I do not like.
