Is the neutral conductor of a portable generator required to be bonded to the frame of the generator?

The neutral conductor of a portable generator is indeed required to be bonded to the frame of the generator. This is essential for safety reasons. Bonding the neutral to the frame establishes a direct electrical connection, ensuring that in the event of a fault—such as a short circuit or ground fault—there is a low-resistance path for fault current to flow. This helps to quickly trip circuit protection devices like circuit breakers, which minimizes the risk of electric shock and potential fire hazards.

Moreover, bonding the neutral to the generator's frame helps to stabilize the voltage during operation, which is critical in ensuring reliable performance and safety in connected electrical equipment. By conforming to these bonding requirements, users can protect themselves and the equipment connected to the generator from potential electrical issues.
