Comment on Code Question of the Day for 05-06-2020 Dear CQD,

In reference to the answer provided for the CQD on May 6, 2020, I disagree with the following portion of the response: "The NEC does not have a provision for using the color purple for high-leg conductor identification.” Section 110.15 of the 2020 NEC allows for the use of the orange color “or other effective means.” As long as the proposed purple coloration is "placed at each point on the system where a connection is made if the grounded conductor is also present” then the installation would comply in my opinion.

Respectfully Submitted,

Michael Hofkin



Hello Michael,

Good to hear from you. Your comment and observation is correct. The NEC doesn't mention the color purple, but it could be chosen to accomplish the later option in 110.15. We agree with your comment. The better way to phrase it would have been, the NEC does not name the color purple for use in identification of the high leg in a system. It could be used as the identification method. We appreciate the clarity and for participating.
