Hi, Part P newcomer here. When taking for example a loop impedence reading on say a ring main, linking live/neutral together you divide the result by 2 to give a reading for each cable because they are the same csa2 but how do you caculate for a live/earth reading when the cpc is a different size? Also information on how to do an insulation test on SELVs or flourescent lighting circuit without linking evey fiitting out?
