I understand that 680.22 says that a pool pump motor 15-20amp 120 or 240volt has to have gfci protection. What about a 3 phase motor?
GFI only if cord and plug connected.
680.22(B) GFCI Protection. Outlets supplying pool pump motors from branch circuits with short-circuit and ground-fault protection rated 15 or 20 amperes, 125 volt or 240 volt, single phase, whether by receptacle or direct connection, shall be provided with ground-fault circuit-interrupter protection for personnel.
Under the 2008 NEC GFCI protected whether cord and plug connected or hard wired.

I stand corrected. See what happens when you don't do things on a dailey basis? Haven't been inspecting since the 2008 came out here in Florida and have been following along and staying informed here on this site. Even read before I posted but didn't see!!!!!!
