From NEC Article 760:
"... The voltage rating shall not be marked on the cable. Voltage ratings marked on the cables may be misinterpreted to suggest that they can be used for Class 1, electric light and power applications. ..."
Did you really read it?
Look at a length of NM wire, it has 600v printed on the jacket. Art. 760 says printing 300v on the jacket is prohibited because it could lead to a misinterpretation of the intended use which does not include what you are proposing to use it for, power applications.
I have a definitive answer from someone who actually knows the National Electric Code and where to look in the NEC, chapter and verse. I would be glad to forward the information to anyone interested.
