I am working in a 100,000 sq ft warehouse, it is 36' to the bar joists. It has racking throughout the warehouse with shipping and receiving areas. There are workstations with desks, computors, copiers and etc throughout the warehouse in various locations. They need power and data to these desks. I want to know how to get power down from the bar joists above to the work stations that OSHA and the NEC will approve. Can I drop from the bar joists at 36' with a cord and put a box with a plug on it? I wold use wir grip (kellems) on both ends of the cord and boxes with hubs.
