In 680.21(C) & (D) Swimming Pools, Fountains, and Similar Installations
The reason for change was: The requirement has been modified to outlets supplying _____________________ with wording that correlates to other GFCI requirements. It specifies pool motors rated 150 volts or less to ground and 60 amperes or less, single- or 3-phase, shall be provided with Class A GFCI protection. This change will expand the GFCI protection requirements to other volt- age systems than previously required. The requirement has been modified to use the term outlet and removed the phrase "whether by receptacle or by direct connection". A part (D) was added as a new requirement for pool pump motor replacement in accordance with part (C) to require GFCI protection. Unfortunate circumstances have driven this much needed change to help protect from electrocution associated with pool motors |

all pool motors and not just pool pump motors |
