If the conduit is on strut with conduit clamps does the strut & clamp have to be PVC coated or could it be steel? Wondering about OVC and steel coming in contact with each other although there are many time where you run PVC with Rigid elbows so I guess that blows my theory/thought away. But then why are there Galvanized PVC coated couplings and one hole straps?
