NEW QUESTION 24
A PV connection is being made at the center of a 300 ft. long 200 feeder. See the attack diagram. The feeder originates in the upper third of the 800A main service panel (800A main breaker) with a 200A breaker and terminates in a 200A main-lug-only subpanel. The rated output of the PV system inverter is 100A.
Which are the NIMUMUM actions required to achieve an NEC-compliant installation?
- A. Install a 200A breaker at the PV source connection point on the portion of the feeder toward the subpanel, maintain the capacity of the entire feeder, and move the 200A breaker to the bottom of the main service panel, away from the 800A main breaker.
- B. Install a 200A breaker at the PV source connection point on the portion on the portion of the feeder toward the subpanel and move the 200A breaker to the top of the main service panel, adjust to the 800A main breaker.
- C. Install a 325A breaker at the PV source connection point on the portion of the feeder toward the subpanel. Increase thecapacityof the feeder from the main panel board to 325A breaker to the bottom of the main service panel, away from the 800 main breaker.
- D. Install a 325A at the PV source connection point on the portion of the feeder toward the subpanel, increase the capacity of this portion of the feeder to 325A, add a 200A main breaker to the subpanel, and move the 200A breaker to bottom of the main service panel, away from the 800A main breaker.
Answer: C
