    The exam has the correct answer as being false but I'm relatively certain ground fault protection is required here. I know there are exceptions to the rule, but I don't think this would meet any of them. Can anybody point out what I am missing? Thanks.

    There are a few exceptions:
    http://www.cooperindustries.com/cont...ements_GFP.pdf

    Specifically:
    "Where Ground Fault Relays are NOT Required
    There are many services and feeders where 230.95, 215.10, and 240.13 do
    not require ground fault protection including:
    1. Continuous industrial process where a non-orderly shut down would increase
    hazards.
    7. Service with six disconnects or less (230.71) where each disconnect is less than
    1000 amps. A 4000A service could be split into 5 - 800A switches.
    9. Fire Pumps
    10. For feeders where Ground Fault Protection is provided on the service (except for
    Health Care Facilities. See 517.17.)"

    It's only applicable to the service, not all breakers. Article 230 is services.
