When would a expansion joint be required for RMC in a vertical run? Article 344 doesn't seem to address this as table 352.44 does for PVC.
My application is RMC in the overhead of an industrial steel trussed roof. The building isn't air-conditioned. The vertical drops to various equipment and wire-ways located 35 feet below are where my concerns lie.
I may be overly concerned but desire any rules of thumb, voices of experience or calibration, (ie... "Its in the code you missed it.")
Thank in advance...
