What is the minimum sizing requirement for main bonding jumpers and system bonding jumpers based on?

The minimum sizing requirement for main bonding jumpers and system bonding jumpers is based on Table 250.102(C)(1). This table provides specific guidelines for the proper sizing of bonding jumpers, which are essential for effectively connecting the grounding system within an electrical installation. The requirements take into account the size of the service conductors, ensuring that the bonding jumpers are adequately sized to handle fault currents and provide a safe path for these currents back to the grounding system.

Understanding the sizing requirements is crucial for compliance with electrical codes and ensuring the safety of the electrical system. By adhering to the specifications outlined in this table, electricians can ensure that the bonding jumpers are capable of performing their functions without risking overheating or failure during a fault condition.
