- Replace the entire system rather than address churn (shutoff) ≤140% of rated (scenario variant 23) per the standard ✅ The recognized standard procedure governing churn (shutoff) ≤140% of rated (scenario variant 23) is applied as specified
- Use a generic municipal bylaw in place of the NFPA / referenced standard for churn (shutoff) ≤140% of rated (scenario variant 23)
- Ignore the requirement for churn (shutoff) ≤140% of rated (scenario variant 23) since it is non-mandatory
Correct answer: The recognized standard procedure governing churn (shutoff) ≤140% of rated (scenario variant 23) is applied as specified
