Are you trying to make a substitute for a flexible cord above a drop ceiling?
I am not aware of any cord connectors ("plugs") that have been evaluated for use with LFMC. Let me expand on that: I have personally done the strain relief tests on such assemblies, and they failed miserably.
I do not see any code section that specifically addresses the use of LFMC above ceilings. For that matter, I do not see where pipe is specifically discussed for use above ceilings.
LFMC is permitted where 'flexibility is required.' Do you require flexibility?
LFMC is not allowed where 'subject to damage.' Does passing it through the ceiling make it subject to damage?
