A power connector includes a terminal block holding terminals in terminal channels with terminating ends configured to be electrically coupled to corresponding wires at separable interfaces. The power connector includes a rear insert covering the terminating ends of the terminals having wire ports configured to receive the corresponding wires during a wire poke-in process. The power connector includes biasing members associated with the terminals each including a pusher configured to be biased against the wire to push the wire into direct physical contact with the separable interface of the corresponding terminal. The power connector includes a release mechanism includes a plurality of pusher release elements. The release mechanism is actuated to release the pushers of each of the biasing members from the corresponding wires.
