Which NEC section oversees bonding of flexible type conduit?

NEC Section 250.102
NEC Section 250.134
NEC Section 250.118(5)
NEC Section 300.13

The correct answer is: NEC Section 250.118(5)

The bonding of flexible type conduit is specifically addressed in NEC Section 250.118(5). This section details the requirements for various types of conductive materials that are permitted as equipment grounding conductors. Flexible conduits must ensure effective grounding to prevent electrical hazards, and this section identifies which types of flexible metallic conduits can serve as an effective pathway for grounding. Understanding the importance of bonding is critical in the electrical field, as it reduces the risk of electric shock and ensures the safe operation of electrical systems. In this context, other sections might pertain to grounding or bonding in general, but 250.118(5) specifically highlights the requirements and acceptable types of flexible conduit for the purpose of bonding. Thus, it is essential to reference this section for guidance on how to effectively bond flexible conduits within electrical installations.
