1. An arrangement for mounting and wiring electrical components in switchgear construction, the arrangement comprising a robot with an end effector designed as a gripper, a mounting plate holding device, with which a mounting plate is held in a mounting position with respect to the robot, and a component supply in the access area of the robot, via which components to be mounted on the mounting plate are provided for removal by the robot, wherein a controller of the robot has machine data for controlling the robot including position data for the arrangement of components on a mounting plane of a mounting plate to be equipped, wherein the robot has an optical imaging system which is adapted to detect an orientation of a mounting plate with respect to the robot, the controller of the robot being adapted to provide, as a function of the detected orientation, the position data with an offset representing the orientation of the mounting plate with respect to the robot, wherein the optical imaging system comprises a stereo camera whose two optical axes are arranged at an acute angle to the gripper, wherein a distal gripper end is located in the imaging area of the optical imaging system, wherein the optical imaging system is arranged to determine an orientation of a cable end, preferably a ferrule of the cable end, with respect to the gripper.
