According to the NEC®, which section allows for the bonding of normally non-current-carrying metal parts of portable generators to the generator frame?

The correct section allowing for the bonding of normally non-current-carrying metal parts of portable generators to the generator frame is indeed specified in 250.34(A)(2). This section outlines the requirements related to the grounding and bonding of generators used in a temporary manner. It highlights the importance of ensuring that non-current-carrying metal parts are adequately bonded to the frame of the generator, which provides a necessary path to ground in case of fault conditions. This bonding helps prevent electric shock hazards and contributes to the overall safety of the electrical installation by maintaining a proper grounding system.

The rationale behind this bonding requirement is to ensure that if a fault were to occur, the electrical current would have a safe route to ground, reducing the risk of electric shock to individuals and damages to equipment. The bonding of metal parts to the generator frame is crucial in ensuring the safe operation of portable generators, particularly when they are utilized in various temporary setups, as they might be in construction sites or outdoor events.

Other sections mentioned, such as 250.30(1), 250.32, and 250.36, cover grounding and bonding requirements for different situations and types of installations, but they do not specifically address the bonding of metal parts of portable generators to
