Solutions for the drop ceiling type issue that have come up at various jobs, that had permits and inspections:
Bar box to ceiling grid, support wire to framing, twistlock receptacle in box facing down, suitable cord w/twistlock male cap, and 'whatever on 'load' end. When equipment was placed, it was plug & play.
Installing a cord reel. Yes, it's ugly, but in certain places, it works.
With the open ceiling issue, dependent on the height, using RGS to the compliant limit of 20' secured on both ends works.
