I am working on a commercial pool project where the pool designer has located below grade pump vaults (Roughly 6'x 3.5' x 32" deep) adjacent to and around a lazy river pool.
They have provided drains for the vaults in compliance with 680.12.
They will separate the disconnect a minimum of 5'-0" from the pool.
My concern is they are asking us to put a disconnect and the motor connections below the maximum water level in these vaults. With 12" supply and return lines running into these vaults if anything were to go wrong the vault could fill up with pool water and submerge the disconnect and motor connection and potentially electrify the pool water. As such this request does not feel prudent. However, I haven't found any code reference that outright prohibits it.
The ultimate goal of NEC 680 seeks to keep people and water separated from electricity. It seems that it tries to keep electrical connections above the maximum water level to prevent the failure scenario described above.
Thoughts?
Opinions?
