Best Answer

A knockout is a pre stamped hole in a distribution panel. The metal slug in the pre stamped hole requires knocking or prying to remove it from the panel. Once the slug is removed from the hole, a cable connector is fitted through and secured with a lock nut on the inside of the panel. A wire cable is then threaded through the cable connector and held securely in place by the connectors wire clamp.
