Hopefully someone can help me shed some light on this or lead me in the right direction. The now one generation older Lutron QED motorized shading system uses a 7 conductor (2) 16AWG (5) 18AWG cable, Liberty Cable markets it as their Lutron-RED brand. The motors use 24VDC, but are fed 24VAC from the 10 motor power panel (which runs on 110VAC) through a 3A circuit breaker (for each motor), down through 2 conductors (16AWG) in the cable to the motor where it is rectified into 24VDC to run the motor and/or a wall keypad.
The specification on the Liberty Lutron-RED is show here:

(click on the specification tab)
Summary here:
LIGHTING CONTROL: LUTRON SIVOIA QED 18/4 stranded twisted shielded + 16/2 stranded twisted + 18/1 stranded 300V CL3 jacketed .340 OD
So you can see that the wire is rated at 300V and does run low voltage AC power.
My question is if I can run 110VAC on this wire to run 110VAC Shade Motors? The 110VAC Somfy shade motors range from 1A to under 2A depending on lift capacity. Also shades typically do not run more than 30 seconds up or down, if that makes any difference.
The job is in Las Vegas, NV, but we do work nationwide so I am curious if something in the NEC will allow what I am asking (realizing that it still may not satisfy the inspector).
I want to make sure I am safe, clean, and legal. Other shading companies have approved and recommend using the Lutron Cable with 110VAC, but I am not so sure and Liberty isn't very sure either. Do you think I could ask the LV Electrican Inspector or some other official body if the answer isn't found here?
Thank you very much for your help. -Tim
