Two Circuits & Two Different Voltages

[wickerham]

I have a piece of equipment that has two circuits coming out of the product circuit #1 labeled 120 volts and ciruit #2 labeled 277 volts.

I have a junction box that will be for the 120 volt hookup and another for the 277 volt hookup.

The two circuits are running side by side in the tubing that will be attached to the juction boxes.

The question I have can two different voltages run through the same tubing and meet NEC codes. If they can not what needs to be done to make this work.

The product appears to have only one exit for wires.

Please help me in this matter.

Thanks

Wayne

These two circuits can occupy the same raceway or enclosure. The insulation value would have to be equal to 277 volts or greater for both circuits.

Also don't forget about the rules in 200.6(D) and 210.5(C).

Thanks Don, I should have mentioned that in my first post. The grounded conductors from different systems need to be identified by a means that distinguishes them from each other.
