Wrenches, For a community water supply, I will be installing two identical SQ Flex systems, each with CU200 interface and IO101 for generator AC backup capability, with 4 Sanyos on a pole-top rack. Because these are community rather than private, I want to pull a permit.
I have done a number of SQ Flex installations, but never inspected. In fact, conventional wells are never electrically permitted here (and it shows). I know that the Grundfos equipment is not Listed, and I expect to argue that nothing else for this application is either. But I'm open to tips on how to do the best Code-approximating installation, using "common sense" approaches. Should I add an HU361RB to each, should I add an IO100 to function as a disconnect, or can I rely on the IO100 switch to also serve as array disconnect? I'll ground properly, use Grundfos' surge arrestors, and ground to a rod and also to the array poles as supplemental grounds. I'll use NM Flex between boxes, and transition from the sub cable to THWN at the well head. I'll also have a P2Flow pressure transducer system with its own independent 12V power supply on each pump system, for distant full-tank shutoff. Other suggestions, please, specific to Code compliance?
