NEC Requirements for Generators and Standby Power Systems

conductor, the generator is considered a separately derived system [Article100]. Figure 445–5. A neutral-to-case con-nection (system bonding jumper) is required at the generator [250.30(A)(1)] to provide a low-impedance fault current path back to the power source.
