Good morning everybody. I want to know if someone can answer this general questions about NEC.


1. Is there an specific acticle on NEC which states the exact color for each line on a 3-phase or single phase installation should have? I know articles 250.119; 215.12;210.5 mention that I can install marking tape and an specific color code. However, I haven't found the exact recommended color code for each type of electrical system.

2. On Chapter 9, table 9. It states that the table is for 600 V, 3 phase, 60 Hz, 75 °C. However, when you have a single phase or DC installation you still use this table as a refference or do you use other table?


Thank you in advance for all the help you can give me on this subject.
