CABLES

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

errors due to leakage from other equipment. Check each conductor to gr

ound and /or lead sheath by connecting one megohmmeter lead to a grou
nd and /or lead sheather and the other megohmmeter lead to each of the
conductors in turn. Check insulation resistance between conductors by co
nnecting megohmmeter leads to conductors in pairs.
