Sorry for the ignorance people but, our University just built this fancy fountain.
The sump pump along w/ the controls, timer and pump related equip are in a underground vault.
It just rained recently and the GFCI circuit for the sump pump had tripped. Water was almost to the controls. I suggested calling back the contractor to replace sump pump. Contractor says there was a surge that took place?!(*&^(
Is the motor on a sump pump (or any single phase motor) that is on a GFCI circuit supposed to have a certain rating/designation/efficiency? This has happened a few times already.
Frank, can you direct me to where in the code that it says that a sump pump for a fountain not be GFI protected? This is an in ground vault about 5' deep containing the fountain pump, fiber optic lighting and controls for the fountain. Thanks.

I think there's a bit of confusion over what type of pump you are talking about. When I hear 'sump pump' I think of a pump that is installed to prevent flooding, or an ejection pump. It operates on a float switch which turns the pump on when water rises to a certain level. I'm reasonably sure that this is what Frank and Redsy are referring to.
Is that what you mean? Or are you referring to a pump that shoots the water in the air for the fountain?

In the vault there is a sump pump that prevents flooding of the vault. It has a float used to switch on the sump pump. There is a pump that cirulates water and pumps water into the fountain. My problem is that when the sump pump circuit which is on a GFI circuit trips, the controls are in danger of water damage (if the water level gets that high). Is there a certain motor I should use on a GFI circuit? Code says that the sump pump has to be on a GFI circuit. Actually the fountain pump (for pumping water into the fountain) has to be on a GFI circuit also. Thanks.... Mike

I don't believe the intention of 680.51(A) requires you to include your sump pump as a part of "fountain equipment". The submersible pump they refer to is a pump that would sit at the bottom of the reservoir that is filled with the water that you are circulating through your fountain. I think you can remove the GFCI from the sump pump.
