how many mega ohms insullation of the cable can't be use
when testing with megger tester for Low voltage cable 240V
use?
Answer Posted / k.prakashchandra
Without armour you can not get the correct IR. Larger the
area of conductor the thicker is insulation layer and you
have to use 500 V megger which will read not less than 5 M ohm.
