.....and should i be able to find this in the NEC code book?

Are you asking if a 120V conductor can short a 4,160V conductor? If the 4.16kV conductor doesn't have insulation, it will damage the insulation of the 120V conductor and it may create a short circuit due to the voltage differential. If the 4.16kV have insulation might be no problem.
Remember that 120Vac conductors insulation are rated to 600Vac, higher voltages in contact with the insulation will damage it.

Depends on what you mean by "cross". The code will allow different voltages in a conduit or raceway as long as the insulation on ALL wires is rated for the highest voltage. So if you 120V conductor has 5KV insulation then its OK.

Not without a transformer to match the two voltages. Depends on the details of your application. I assume that the 2 voltages are AC.
