are made all organic insulating materials should be inspected ror
visible leakage current paths, and necessary action must be taken to
replace insulation that may have been affected by moisture absorption.
The high potential test is also recommended for devices which have been
removed from service and stored over an extended period of time under
unfavorable atmospheric conditions.
NOTE:
Before applying a hi-potential test make certain that the switch
has been disconnected from both the source and load.
If the SE-lOOE secondary wiring is to be given a hi-potential test at
1500 volts, remove both of the motor leads from the terminal board.
Failure to disconnect the motor from the circuit may cause damage to the
winding insulation.
