What must an installation comply with if overcurrent protection exists for conductors from a grounded separately derived system supplying a separate building?

When dealing with an installation that includes overcurrent protection for conductors from a grounded separately derived system supplying a separate building, it is essential to refer to the appropriate sections of the National Electrical Code (NEC). The correct choice pertains to Section 250.32(B)(1).

This section specifically addresses the requirements for supplying a separate building with conductors from a separately derived system, emphasizing the need for proper grounding and bonding practices. It outlines that when a building is fed from a separately derived system, the conductors must be protected against overcurrent and that they must also follow the grounding requirements specified to ensure safety and reduce the risk of electrical faults.

Understanding this section is crucial because it directly relates to the practices that ensure electrical safety in installations with separate buildings, particularly when they are supplied by their own grounded systems. This alignment with section 250.32(B)(1) helps meet the necessary standards for grounding and overcurrent protection in such configurations.
