Is there anything in the code that says I cannot run 2 parallel runs of 2 1/2" conduit overhead between steel beams
over the uninhabited space of a future tenant? This is in a business complex building that has other establishments on one side and empty space (as of now), on the other side. I will be going over the empty space. As of now there are now "firewalls" that I will have to penetrate. I assume though, after the establishment I am figuring this bid on is built, they will have a "firewall" separating them from one side of the "empty space".
It shows running,(2)sets of (4) 3/0's and (1)#3 ground
to a 400 amp main lug panel. Thanks, Steve..

BTW, the outside is asphault, so there no going underground
unless major cutting.
