Sorry I should have elaborated more from the beginning.
I am using the panel as a service disconnect for a lineside connection (can’t use a fused/bladed disco because of space constraints). Originally I bought a QO 70A panel, but soon realized that the Square D retention clip (PK2MB) is only compatible with their larger panels. So I bought a larger panel (100A 8 Circuit) and then received some feedback that having the open spaces (even if labeled that “Do Not Add Loads”) could raise a flag with an inspector. So then I was back on the hunt for a dedicated 2 Pole 60A or 70A panel with a compatible retention clip for a 30A breaker. Eaton’s retention options only start in the 60A range (the smaller breakers don’t have the hole in them to put the bolt through). Square D said they don’t have an option for their 70A panel. There aren’t any good Siemans distributors near me but I wasn’t finding an option via google for them either. I talked with another Wrencher on the phone and received this feedback which I’m just going to cut and paste to include it in this thread: “The NEC doesn’t require a hold down clamp for the circuit breaker unless it can be backfed from a multi-mode or stand-alone inverter (690.10(E)). The language implies that a hold-down is therefore not required elsewhere. Most modern breakers (def. QO’s) are not marked “line” and “load” so no problem there (also in same code section). Even when it was a requirement for all PV outputs, John Wiles had argued that taking off the panel cover, which required a tool, served as the hold-down, and this was generally accepted.” So taken that advice I’m back to using the QO 70A panel but without a retention clip (or calling the lid the "retention clip"). For what its worth I have passed inspections prior using the retaining clip from a generator interlock kit (QOCGK2C) on a QO 100A panel, but felt like there must be a better option out there....
