ABSTRACT:
A load separable connection is provided, including a loadbreak elbow having a contact probe, and a bushing into which the contact probe is received in a tulip contact therein. An ablative insert, including a projecting lip extending over the outer circumference of the tulip contact at the end thereof, is provided within bushing. The insert helps extinguish arcs created during live connection of the elbow over the bushing, and also helps physically block the access of the arc to the bushing components surrounding the tulip contact.
