The handle locking attachment is for locking a pivotal external operating handle of an electrical control device in the OFF position. A frame mounted on the enclosing case of the device supports a bail which, when the operating handle is in the OFF position, can be swung to an obstructing position wherein it prevents movement out of OFF position, and can be locked in the obstructing position by a padlock shackle passed through an eye on the frame. The bail is biased by a torsion spring away from the obstructing position to an unobstructing position in which it is juxtaposed against the front face of the case so as not to interfere with the closure of the door of a load center cabinet in which the control device is mounted.
