At an inspection there were several protective devices, circuit-lock's - manual motor controllers as disconnects. Not fuse breakers I am use to seeing uses as a means for/of mechanical HVAC disconnect.

Question; what protective equipment is required for HVAC equipment?
Section 430.102, the controller in 430.102(A) and the motor in 430.102(B)
2008 NEC. Section 430.102(B)(1) requires a disconnecting means for each motor, and it must be located in sight from the motor location and the driven machinery location. “Within Sight” is visible and not more than 50 ft from each other [Art. 100]. Or, the controller disconnecting means [430.102(A)] can serve as the disconnecting means for the motor if the disconnect is located in sight from the motor location [430.102(B)(2)]
Question. Am I sparking up the wrong tree in the NEC?
