From time to time, depending on the conductor size, an electrician has to re-identify a conductor as a grounded conductor or a grounding conductor. Wrapping the conductor with green electrical tape is the most common way to re-identify a grounding conductor. White tape is used to re-identify a grounded conductor. Discuss the difference in the way a grounding conductor is re-identified with green tape and how a grounded conductor is re-identified with white tape
