Can anyone tell me what table A722 is for? (in the appendix, under the heading "Guidance on voltage monitoring device described in Regulation 722.411.4.1 (iii)")- given the requirement in the regulation itself is for 'within 5s' for any voltage over 70V and need not open in less than 4s? (I presume the latter bit is to reduce the chances of false tripping caused by ordinary L-PE or L-N faults elsewhere on the same LV system).
