Kirk,
That is correct. Raceways are not rated for voltage. The key is whether the conductor is intended to be installed in a raceway or not. Raceways are also allowed to be used for physical protection only for direct buried cables and exposed cables. The raceway is only required to prevent physical damage in those applications. The conduit is chosen based on what level of physical damage is expected. For instance, Rigid Metallic Conduit is generally used above ground in parking structures because of the possibility of being struck by a vehicle. Bill.

Hello, Is there any specific conduit you'd recommend for 1000 volt arrays? I can't find any reference of a voltage rating for EMT, ridged, PVC, etc. in the code or spec sheets. Are these types OK to use? I assume its OK as long as 1000v rated wire is used. Am I correct? Thanks.
