The system bonding jumper for a separate derived system should be connected at any single point from the source to the first system disconnecting means. This is important because the bonding jumper serves to establish a low-resistance path for ground faults, ensuring that all conductive parts of the installation are connected to the ground reference point.

By placing the bonding jumper from the source to the first disconnecting means, it ensures that the entire system is referenced to the same ground point, which is essential for the safety and effective operation of the grounding system. This approach minimizes the chances of ground potential rise during a fault condition and contributes to the overall stability and reliability of the electrical system.

Connecting at any point along this path allows flexibility in system design while maintaining compliance with safety regulations, ensuring that personnel and equipment are adequately protected from electrical faults.
