Can anyone provide me with any regualtory guidance on the use of drop cords in an industrial setting. I have a facility that has almost all of their equipment/machines running off of heavy duty electrical cords which hang down from the ceiling. They even have some cords that have outlet boxes attached to the ends for use in regular table-top appliances.
I come from the school that anything over 90 days is defined as "permanent" and is to be "hard-wired" in conduit with a disconnect means near-by. Their argument for this is, they are always moving equipment around for efficiency and thus use the cords.
Is this a violations of OSHA or NEC standards?
