I believe that the code requires use of expansion joints whenever there is possibility of 1/4" or more of thermal expansion in conduit runs. I have found expansion joints for pvc that works just fine, however my question is about the right choice of straps to allow for movement of the conduit, but not be too loose, causing problems at the time of wire pull. Anyone have good/bad experiences with this? Thanks,
