Section 296-96-23432. What requirements apply to speed governors?
Latest version.
- (1) A speed governor must be provided, except as specified in subsection (2) of this section. Its operation must cause the interruption of power to the driving machine if the speed of the steps exceeds a predetermined value, which must be no more than 40 percent above the rated speed.(2) The speed governor is not required where an alternating current squirrel cage induction motor is used and the motor is directly connected to the driving machine. (NOTE: The governor may be omitted in such case even though a chain is used to connect the sprocket on the driving machine to the sprocket on the main drive shaft.)
