680-6(d) Motors other than Dwelling units.
Wiring supplying pool pump motors rated 15 and 20 amps, 125 V or 240V, single phase, whether by receptacle or direct connection, shall be provided with ground-fault circuit interupter protection for personnel.

Ok fine, i do a call to a municipal pool who's 3-phase motor has taken many a bath in the pump house due to bad pipes, only to find that #1-no GFI #2-NEC says to H____with it & #3-can't get a 3 ph GFI

So does 3 ph power somehow mix with H2O safer?

Would you swim in this?
