Ground Rod requirement

[transman2]

Is it required to install a ground rod at a lift station control panel if 3 phase power is run from one panel at a building/structure then underground to a new lift station control panel. A grounding conductor is run with the power circuits but for some reason I'm thinking that if its more than one circuit or could be considered another structure that a ground rod would be required there also. I hope I explained this ok. Thanks for any and all help.

Should that "control panel" supply more then one load this would raise the question if there is more then one circuit.

Place a convenience receptacle or light at the separate structure and it is very likely not a single circuit application.

That said the disconnecting means at the separate structure needs to be suitable for use as service equipment as well.
