Could anyone confirm if we test 100mA RCD's at x5?

There is a lot of information on the web that says you only test at x1 but Table 3a in appendix 3 clearly shows a max disconnection time for a 100mA RCD at x5 to be 40ms.

Thanks all.
 
It might be that I've never taken notice of it Andy, can't be bothered to go out to the van in the current atrocious weather to check now though.:) The only time I ever installed a 10ma RCD was about 35 years ago when an apprentice, it was for a Hydrotherapy pool in a centre for disabled children and back then it was a massive lump, fixed to the wall with M12 Rawlbolts.
