Square D Ground Bar Insulators

Square D Ground Bar Insulators

The Square D PKGTab ground bar insulators are heavy-duty insulating supports designed to safely mount ground bars inside electrical enclosures while maintaining required electrical isolation. Built for dependable performance in panelboards and enclosures, these insulators help keep grounding systems properly separated—so electricity goes where it’s supposed to, and not on an unscheduled adventure.

Country of Origin
