ABSTRACT:
The triggered wildlife guard is formed from first and second body sections hinged together to pivot between an open and a closed position. In the closed position, the first and second body sections latch together to form a hollow body open at a first end and having a top wall at a second end which defines a conductor opening. A spring assembly biases the first and second body sections toward the closed position, and a releasable trigger extends between the first and second body sections to hold them in the open position until the trigger is released. A wire stop formed on the first and second body sections bridges a gap therebetween in the open position to retain a bushing lead wire in the conductor opening.
