This 60A/125V 3-pin Mole-Richardson Male Bates Connector is used in theater and film applications to provide a safe and secure connection for normal to high-powered lights, depending on the connector's rating. Once attached to the fixture's cable, it is usually plugged into a multi-outlet gang box that distributes power to several on-set lights.

The connector's 3 pins are purposely positioned and sized asymmetrically so that they can't be joined incorrectly and so that the ground pin inserts first and is removed last.
