The new Washington State rule says no. So where in the NEC does it say no?
Here is the Washington explanation:
"Do HVAC Damper Actuators Need Motor Disconnecting Means Per NEC Article 430?
No, an actuator is considered a component of the damper assembly and is not subject to the disconnect requirements of NEC 430.101. Though often called by other names such as damper motors, damper operators, or motor packs, damper actuator is the appropriate term. A damper actuator is not a motor subject to NEC Article 430. Dampers are available with a wide variety of actuators installed. Some dampers are shipped without actuators and intended for installation of an actuator in the field after the damper has been mounted in the HVAC mechanical duct system. All actuators on UL classified Smoke and combination Fire Smoke Dampers must be furnished and installed by the damper manufacturer at the time the damper is manufactured. Regardless of the specific application, all dampers should be installed in accordance with the installation instructions for the damper assembly."
