Lockout device for switchgear

A safety lockout device for switchgear comprising:

• an electrical motor for operating the switchgear, the motor including a motor shaft having a portion extending outside a motor housing;
• means for electrically disconnecting power to the motor mounted on an exterior surface of the motor housing;
• means for mechanically blocking the motor from operating mounted on the motor shaft;
• and
• a movable member operable by a hotstick to actuate the electrical disconnecting means and to mechanically engage the mechanical blocking means at a location exterior to the motor housing;
• wherein a position of the movable member relative to the electrical disconnecting means and mechanical blocking means provides a visual indication of the operating state of the switchgear.

A safety lockout device for switchgear comprising:

• a motor box including an electrically operated motor mounted to the switchgear;
• a single pole switch mounted on the exterior surface of the motor box and electrically connected to the motor, the switch having an open position and closed position;
• a movable member mounted on an exterior surface of the motor box, the movable member being adapted to move between a first position and a second position;
• and
• a blocking arm coupled to a shaft of the motor extending outside the motor box, wherein in the first position, the movable member engages the switch to close the electrical motor circuit and the blocking arm is free to rotate with the motor shaft, and wherein in the second position, one end of the movable member does not engage the switch and the switch is in an open position interrupting power to the motor and the other end of the movable member extends beyond the motor box housing so that upon operation of the motor, the blocking arm engages the movable member to prevent rotation of the motor shaft and a change of state of the switchgear, and wherein the position of the movable member relative to the switch provides a visual indication of the operating state of the switchgear.
