I don't think that there is a max voltage for conductors in parallel.

i think this may be a HV question with regards to parallel pulls between switchgear and equipment?

Is it at all possible that you slightly misunderstood or misread the question??
The only rules I can find that refer to maximum voltages between conductors are the following:

12-502 Maximum Voltage. Nonmetallic-sheathed cable shall not be used where the voltage exceeds 300 V between any two conductors.

12-1608 Maximum Voltage. The voltage between conductors contained in surface raceways shall not exceed 300 V unless the raceways are marked for a higher voltage.

The question was what is max. voltage for conductors in parallel.
Simple short question...

There is only one rule in the 19th edition of the CEC that tells us anything about voltage as far as conductors in parallel is concerned and that rule is 12-108(c). The insulation class (voltage withstand levels and temperature rating) must be the same for conductors in parallel.
