Which requirement is not specified by Section 250.24 for the main bonding jumper?

The requirement that the main bonding jumper shall be re-identified at the terminals when furnished with insulation in any color other than green or natural gray is not specified by Section 250.24. This section primarily focuses on the structural and installation requirements of the main bonding jumper, including its unspliced nature, the necessary connections within service disconnect enclosures, and its role in properly connecting the grounded system conductor to the equipment grounding conductor.

While color identification is critical in electrical wiring to ensure safety and compliance, the specifics about re-identification for color-coded insulation are typically outlined in other sections of the National Electrical Code (NEC), particularly under Article 250. Therefore, while it's important for identification to be clear, this particular requirement does not fall under the detailed mandates of Section 250.24.
