1. A busway system, comprising:
a first busway including a first end;
a second busway including a second end;
a joint seal coupling the first busway to the second busway in a facing relationship, the joint seal including (i) panels configured to at least partially slide over the first end of the first busway, and at least partially slide over the second end of the second busway to couple the first busway to the second busway in the facing relationship, and (ii) a rib extending from an inner surface of the panels, the rib acting as a stop limiting how far the panels are capable of sliding over the first and second busways, wherein the joint seal creates a seal at both a first joint formed by the first busway and the rib of the joint seal, and a second joint formed by the second busway and the rib of the joint seal, such that the rib is positioned between the first and second ends of the first and second busways;
a coupler positioned over the joint seal to cover both the first joint and the second joint; and
a coupler seal positioned over the coupler.
