in 2011 680.21(C) is pretty unambiguous
(C) GFCI Protection. Outlets supplying pool pump motors
connected to single-phase, 120 volt through 240 volt branch
circuits, rated 15 or 20 amperes, whether by receptacle or by
direct connection, shall be provided with ground-fault circuit interrupter
protection for personnel.
