When suspending electrical conduit from the ceiling in a warehouse (EMT or Rigid), that runs perpendicular across unistrut, how far apart are the unistrut allowed to be?
What type of conduit is allowed? EMT or Rigid?

Support is required as specified for the conduit - unistrut does not make any difference in the required support spacing.
For EMT, the required support is within 3 feet of each termination, and a minimum of every 10 feet.
I'm not as familiar with the support requirements for rigid, it's too rich for my blood. Whatever they are, they are not influenced by the support being unistrut.
