Regarding the Code Question of the Day that was answered on April 29, 2020
Hello, you must also take a look at 200.6(D) which does NOT have the trigger of having the conductors being spliced or terminated within an enclosure, the identification of the grounded conductor is required even if passing through a box if different voltage systems exist in the enclosure.
Tuesday's Answer:
Hi Jeff,
Thanks for the question. The short answer is no. The rules for identification of branch circuit conductors and feeder conductors are provided in Sections 210.5(C) and 215.12( C). Identification means is triggered if there are one or more nominal voltage systems in the premises wiring system. The second trigger is that such identification is required only if the conductors are terminated, spliced, or otherwise connected within the box. See each of these Code sections for the complete identification requirements.
