[QUOTE="sanny, post: 153516, member: 1327"] That wasnt my point! The EAWR 1989 says 14. No person shall be engaged in any work activity on or so near any live conductor (other than one suitably covered with insulating material so as to prevent danger) that danger may arise unless- (a) it is unreasonable in all the circumstances for it to be dead; and (B) it is reasonable in all the circumstances for him to be at work on or near it while it is live; and © suitable precautions (including where necessary the provision of suitable protective equipment) are taken to prevent injury. If you have measured Ze and R1+R2 then you have already measured Zs I have also watched an NICEIC training video which said we shouldnt be doing live Zs tests [/QUOTE]
