Hey Joe,
That is a good idea to keep your plugs and sockets the same so you can move machines around as necessary. I will have conduit on the walls for 120V, I wonder if 3/4" EMT would work for those circuits. Most of my 3-phase I believe will be run on top of the lower cord of the trusses as they will drop to my machines that are not near walls.?
I was going to run Prevost air lines in a similar manner around the shop. I will look into MaxAir lines, thank you for the recommendation.
John??
