  5. According to NEC 445.13, the minimum conductor ampacity for generator output terminals and conductors within the generator enclosure must not be less than what percentage of the nameplate current rating?

    Answer: 115%

    NEC 445.13 requires generator output conductors and terminals to have an ampacity not less than 115% of the nameplate current rating.

  6. NEC 680.22(A) restricts the placement of receptacles near permanently installed swimming pools. What is the minimum distance from the pool wall for receptacles?
