ABSTRACT:
The present invention provides a connector bar for making electrical connections to terminals having a lug body with an externally accessible interior cavity and a binding screw. The connector bar includes an elongated body having two ends and made of electrically conductive material. At least one of the ends having a solid cross-section with a configuration which creates less distortion in the sides of the lug body compared to a round cross-section configuration when the binding screw contacts the end with torque applied for making the pre-determined mechanical and electrical connection. Preferably, the cross-section configuration of the end is defined by a flat top surface larger in width than the contact area of the binding screw, two arcuate sides having an arc value approximately the same as the interior cavity of the lug body, and a flat bottom surface smaller in width than the top surface. The present invention also provides a main breaker and a panel assembly connected by the above described connector bar in a load center.
