Chapter 3 Wiring Methods and Material
covers 310.4. Therefore 300.2A says that this chapter covers only 600 volt cable.

If thats True where in the N.E.C. does it deal with parellel conductors over 600 volts .???? There are Several references to over 600 volts in Art. 310. & 300.3 B(1) referes you to 392.8d Parallel conductors in tray, which is deals with over 600 volts in that section(Tray).

Take a look at 300.1(A)

"Scope.All Wiring Installations. This article covers wiring methods for all wiring installations unless modified by other articles."
Since the over 600V sections do not modify the rules for paralleling I would say that they apply.

It looks like 300.1A got motified by 300.2A.

As far as I can tell the NEC has very little to say about installation of over 600 volt systems.
