ABSTRACT:
A system for indicating a position of an electrical distribution device configured to be racked into an electrically connected condition within an enclosure and racked out to an electrically disconnected condition via a racking mechanism is disclosed. The system includes a rotating indicator having at least a first position and a second position, the first position indicating the connected condition, and the second position indicating the disconnected condition, the indicator operably connected to the racking mechanism to rotate the indicator in response to movement of the racking mechanism between at least the connected condition and the disconnected condition. The system also includes a biasing device to bias rotation of the indicator toward the first position when the racking mechanism is in the connected condition and to bias rotation of the indicator toward the second position when the racking mechanism is in the disconnected condition. The system further includes a first mechanical stop to hold the indicator at the first position when the racking mechanism is in the connected condition, and a second mechanical stop to hold the indicator at the second position when the racking mechanism is in the disconnected condition.
