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.
And therein lies my gripe, because the rules say must operate in 40ms or less testing at 5 times or higher
Then that must be ok as testing 250mA is (one example of) a test at a higher current, albeit one I think gives the RCD an easy ride and is pretty feeble test of its safety function.
Equally testing at 5 amps would also be 'higher than' and they did not pick that, so perhaps I should be grateful for small mercies.
