Mixing 480 volt and 120 volt.

[jeff1166]

Where in the code book can I find mixing voltages in a gutter. I want to know if is legal to install 480-volt circuits and 120-volt circuits in the same gutter. The gutter is mounted above the two different panels. I want to use one long gutter for both panels.

Its done all the time. But take a look at Art 200 on identification of grounded conductors for more than one system, it may be 200.5...one neutral is white the other has a stripe.

as long as both panels are from the same service there is nothing wrong with it
