Motors, Motor Circuits, & Controllers
An individual disconnecting device must be provided for each controller. A disconnecting means must be located within sight, visible and within 50 feet, of the controller location.
The disconnecting device must disconnect the motor and the controller from all ungrounded supply conductors and be designed such that no pole can be operated independently. The disconnecting device must plainly indicate whether it is in the off or on position.
The disconnecting device must be readily accessible. An individual disconnecting device must be provided for each motor, but a single disconnecting means may be used for a group of motors under certain conditions set out in 29 CFR 1910.305.
