ARTICLE 100, 430.102(A), AND 430.102(B)(2)
The disconnecting means shall be installed within sight of the motor controller. All of the ungrounded (phase) conductors shall be disconnected from both the motor and controller supplying the motor circuit. The disconnecting means shall be installed within sight of the motor and not more than 50 ft (15 m) from the motor. If such disconnecting means is not installed within 50 ft (15 m) of the controller, motor, and driven equipment, other provisions for disconnecting the motor shall be made. The controller has a direct relationship to the disconnecting means and shall be installed within sight and within 50 ft (15 m) of the disconnecting means. The motor does not have a direct relationship with the controller. (See Figure 18-48)
Note, a disconnecting means shall always be required to be located in sight from the controller location. A single disconnecting means shall be permitted to be located adjacent to a group of coordinated controllers mounted adjacent one to another, such as on a multi motor continuous process machine. For further information pertaining to sizing, selecting, and locating such controllers and disconnecting means, review 430.83, 430.102, 430.103, 430.107, and 430.109 very carefully.
