Shock:
'Cord' cannot be used for permanent wiring methods. That said, IF you have a vend with a cord long enough to reach your receptacle, no problem.
IF you are proposing a twistlock to cord to a 1900 box that the machine cord will plug into; that does not fly.
Dependent on the ceiling height, you may want to consider a power pole, or IMC/RGC from ceiling to floor with the recept(s) installed therein.
