When I read 680.23 (A)(3) it says that the GFCI requirement for underwater luminaires should be in the branch circuit. Does this mean that a sub panel protected with a GFCI Main will not satisfy the requirements in 680.23(A)(3)? I say we still need a GFCI in the branch circuit. Note that it doesn't specify a "GFCI in the branch Circuit" when talking about the pool cover, motors or other items needing GFCI protection. Only that they must have GFCI protection.
