Multiple Choice

When checking insulation resistance of motor windings the motor should be ___.

Insulation resistance is measured with the winding de-energized. If the motor is running or under load, current flows through energized paths and leakage through the drive or wiring can skew the reading and hide insulation problems. Also, high test voltages can damage connected equipment. So the motor must be turned off and isolated from power and any circuitry before performing the insulation resistance check.
