In general the NEC does not require hardwired equipment to be GFCI protected, the assumption being that a hardwired EGC is more reliable then a cord and plug connected EGC.

That aside GFCIs are a inexpensive upgrade that may save a life.

Edit, just noticed the 480 volt one, not so inexpensive....

I was waiting and you didn't disappoint me. I was hoping you would have a take on the 480V pump due to the fact that 682.33(B) is 120V to 250V.

The way I read it is the 480v does not need GFI. Why? I don't know....... third Base! Cause the book says.

Thats interesting, a pool is not required to have GFCI protection but an aeration pond is? :-?

I think we need more info about this installation to decide if it is a 'fountain' Article 680 or if it is actually covered by 682.

682 does not apply if 680 does, check out 682.1

Respectfully, I have to disagree with you. There are and have been for some time GF devices for 480 volt, 3 phase.

One is on Bender.org website

Years back I installed two aerators at a pond/water holding at a country club. 480 volt, 3 phase, and the job spec required GF protection (Class A) on the aerators inclusive of the factory cabling. I don't remember what specific brand device I used but it was NOT a GF CB.
