Customer has a small store with registers and a gas dispenser. Single phase

They are wanting a UPS to ride through the time it takes the generator to spool up.

This would need to be hard wired to a subpanel because the affected loads are all over the building.

I am having a hard time finding a UPS that hard wires with conduit, and also surprisingly one that is split phase 120/240.

Local sheriff's office has an APC unit that is 120/208 wired into their distribution. I am looking for something similar to that.

APC / Schneider is the normal choice but I don't find much in their catalog, maybe I am using it wrong. All seems to be single voltage and uses connectors not conduit.

My supply houses are mostly clueless about one-off stuff like this.
 
Surprised you are having a hard time finding one, most of the big box stores use that same size and set up. If I remember correctly, big Orange uses APC.
 
It's just a wild guess on the size, I have to site visit it yet. Just trying to wrap my head around what exists. I went over to Eaton / Tripp Lite, it may be that all the hard wire split phase stuff is big and double conversion. That would probably be overkill. It looks like maybe L5-30 and everything on 120 volts is as close as I will get but I'd like to know if anybody can confirm. Very small mountain store in the middle of nowhere, the gas dispenser is the one thing making this more difficult. It doesn't have to pump gas, it just has to keep the computers alive so they don't reboot.
 
These guys wheel and deal UPS systems for data centers. 6 kVA is small to them, but they have it new or used, reconditioned etc.
