682- Natural and Artificially Made Bodies of Water

[BuckeyePowerSolutions]

So I was contacted a while back by a customer who was having a pond dug into their back yard. And it turns out they had a separate well installed to fill and supply water for this pond. Its a 1/2 HP 240v well pump installed down in the well casing just like any other well pump. I plan to install a breaker lockable in accordance with 110.25 for my disconnect. Now my question, and maybe its a stupid one, are there any requirements out of 682 that I will need to comply with for such an install? The new well pump circuit will come from the existing dwelling. The house has a 200 amp service. There is no disconnect on the service, which a disconnect would not have been required for this service. I'm trying to stay away from installing a remote panel board to avoid the requirements of 682.31 B for feeders, so I am planning on running the new circuit to the main panel board. Would I now be required to install an Equipotential Plane at the existing electrical meter location, which is maybe located 50-75 yards from the new pond? Would my well pump be required to be GFCI protected? Maybe I'm over thinking this but water and electric don't mix. And the name of the game is cover your butt. Looking for some advice and input. Thanks

I don't see any problem if there isn't electricity in the pond itself. The pump doesn't need gfci protection and, IMO, no equipotential plane datum is required.

So, I want to make sure I'm understanding the requirements of 682 correctly. I am looking at installing a sub panel on a house per the feeder requirement in 682.31. The panel will be adjacent to a pond and use to supply equipment for the pond. This equipment will include a 240v hard wired WELL PUMP to provide water for the pond only, an 120v hardwired AERATOR pump for the pond, and a GFCI protected receptacle to be mounted near or on the dock. I plan to install GFCI protection for the aerator circuit. I don't believe I have any need to install the equipotential grid at the panel location due to the fact I won't be supplying anything that will be in the pond itself. With all this being said am I interpreting this code correctly? And could someone enlighten me on what they are referring to in section 682.33 (B) when it talks about the GFCI protection?
