Electrical Question from Robert about Electrical Code
Background: Robert, a Electrician from Perth,New York
Question: Where in the code does it tell you about color coding wires according to the voltage.

Dave’s Reply:
Thanks for your electrical question Robert.
Since 1975  the National Electric Code has not specified coloring of electrical power conductors. It is common practice in most areas to identify 120/240 volt conductors as black and red for electrical services for the home, and black,red and blue for 3-phase 120/208Y electrical services. Local regulations may however amend the N.E.C. The U.S. National Electric Code does have color requirements for grounded conductors.  The N.E.C. section Article 250 is full of all the necessary electrical codes and requirements for grounding. See the Electrical Code link below which will provide you will a listing of codes in the Electrical Grounding Codes area.
