I need to run intrinsicaly safe control wiring (Start/Stop + Speed Potentiometer) from an unclassified location to the operator station in a Class 1, Div 1, industrial location with a dropped ceiling. I was thinking of running multiconductor PLTC above the ceiling. Would this be appropriate? I referenced 504.20, 336.10(7) and 504.30. I'm not sure if this would pass 504.30 if the rest is ok. I know a seal is needed.
Application
I am replacing a mixer that has an across-the-line starter with a new unit that has a VFD to run the motor. So, the power wiring is existing.
Any suggestions or guidance would be appreciated.
