Abstract
Levering-in systems, particularly suitable for electrical apparatus such as switchgears, have a motor that can drive a drive shaft during a powered operation and include a mechanical coupling assembly that can physically disconnect or decouple the drive shaft from a drivetrain coupled to the motor to allow manual levering-in with a reduced user crank force and/or to inhibit damage to components of the motorized drive system.
