1. A jaw assembly, comprising:
a first jaw member including a first arm, a first support base extending from the first arm, and an arm opening defined in the first arm;
an electrically insulative jaw insert disposed adjacent the arm opening defined in the first arm;
electrically insulative first bushing disposed at least partially within a first opening defined in the jaw insert, wherein an enlarged portion of the first bushing is larger than the first opening of the jaw insert to preclude the first bushing from passing entirely through the first opening of the jaw insert;
a second jaw member including a second arm, and an opening defined in the second arm;
a first pin disposed at least partially through the opening defined in the second arm of the second jaw member and at least partially through the first bushing; and
a second pin disposed at least partially through a second opening defined in the second arm of the second jaw member and at least partially through a second opening defined in the jaw insert,
wherein the enlarged portion of the first bushing is positioned between the first arm of the first jaw member and the second arm of the second jaw member.
