Which NEC table is referenced for sizing equipment bonding jumpers?

• A. Table 250.121
• B. Table 250.122
• C. Table 250.123
• D. Table 250.120

Answer: (B)

The sizing of equipment bonding jumpers is specifically referenced in Table 250.122 of the National Electrical Code (NEC). This table provides the appropriate sizes for bonding jumpers based on the rating of the overcurrent protection device supplying the equipment. The importance of properly sizing bonding jumpers lies in ensuring a safe and effective ground-fault current path, which is critical for protecting both individuals and equipment. Adhering to the guidelines laid out in Table 250.122 helps to minimize the risk of electrical hazards by ensuring that the bonding conductors are adequately rated to handle potential ground-fault currents. This contributes to the overall safety of the electrical system and compliance with NEC requirements.
