If you are installing IMC conduit for PV DC source circuits for long runs on a large standing seam metal roof (commercial), should you use conduit support straps that allow the conduit to move within the strap (for thermal expansion/contraction) if the support is attached to the roof via a standing seam clip, or should the strap be tight fitted so that there is no movement allowed (assuming the conduit and the roof expand/contract at the same rate)?
