Correct answer to question 8060
- B: An emergency shutdown device outside the dwelling, readily accessible
Explanation
One- and two-family dwelling generators, other than cord-and-plug portable units, need an emergency shutdown device outside the dwelling at a readily accessible location. This is 445.18(D) in NEC 2020 and 445.19(C) in NEC 2023. First responders can then shut the generator down without entering the building.
