The equipment grounding conductor is sized according to which of the following?

The equipment grounding conductor is sized according to specific criteria outlined in the National Electrical Code (NEC). Generally, it must be appropriately sized to ensure safety and effectiveness in providing a path for fault currents.

The correct basis for sizing an equipment grounding conductor typically involves considerations related to the size of the overcurrent protection device and the size of the conductors supplying power to the equipment. This is established in NEC tables and guidelines that govern the installation and protection of electrical systems.

Sizing the equipment grounding conductor solely based on the size of the circuit conductors or the overcurrent protection is pivotal, as it directly impacts the system's overall safety and functionality. By ensuring that the grounding conductor is adequately sized in relation to these factors, the risk of electrical shock and fire hazards is significantly reduced, promoting a safer environment for both personnel and equipment.

In this context, the choice that emphasizes this specific sizing criterion related to the equipment grounding is indeed the most appropriate, as it aligns with the NEC standards and ensures compliance with safety regulations.
