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?!(*&^( [Linked Image]

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.

Appreciate the help. Great site.
