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  between 
conductors by connecting megohmmeter leads to conductors 
in pairs.
