Self-locking power connector

A power connector for electrically coupling a circuit breaker to an electrically conductive power bus bar, the circuit breaker having a cluster support protruding therefrom, the power connector comprising:

• a cage;
• first and second opposing stacks of electrically conductive asymmetric plates pivotably attached to the cage, each plate having opposing first and second end portions, the first end portions being configured to attach to the cluster support of the circuit breaker, and the second end portions being configured to electrically mate with the bus bar;
• first and second biasing members each engaged with a respective one of the stacks of plates, the first and second biasing members cooperatively biasing the first end portions of the first and second opposing stacks of plates towards one another;
• and
• a retaining member engaged with the cage and the first and second opposing stacks of plates, the retaining member inhibiting the first end portions of the first and second opposing stacks of plates from being urged away from one another.
