CABLES

Disconnect the cable from the line. Also disconnect opposite end to

avoid errors due to leakage from other equipment. Check each

conductor to ground and /or lead sheath by connecting one

megohmmeter lead to a ground and /or lead sheather and the other

megohmmeter lead to each of the conductors in turn. Check

insulation

resistance

betw een

conductors

connecting

megohmmeter leads to conductors in pairs.
