An electrical connector for a threaded stud may include: a connector body having a first end with a recessed portion and an anti-rotation wall extending upwardly from the recessed portion; a connector element configured to electrically connect and secure the threaded stud thereto; and a fastener configured to secure said connector element to the connector body. The connector element is selectively attached to the connector body in either a right-hand configuration, in which the threaded stud is secured on a right side of the connector body, or a left-hand configuration, in which the threaded stud is secured on a left side of the connector body. The anti-rotation wall engages a side wall of the connector element to prevent the connector element from rotating about the fastener relative to the connector body.
