I'm trying to determine why you are having a hard time with this part of the code. I believe you are over interpreting it.Don't you love the precise nature of the NEC???

Sometimes precision (in a prescriptive context) is not the goal. In this particular case though I think you are reading too much into it. A disconnect can have a cover, dead-front, and live-front. The cover can only use a key (if presenet). The dead-front must use tools. The live-front is behind the dead-front so additional tools are not required. DIN rail breakers without a bezel lack a dead-front.Don't you love the precise nature of the NEC???
Technically they aren't OCPDs, they are disconnects rated for the voltage and current.Mike Holt's comments on readily accessible.
It's also worth mentioning that most PV circuits rarely need OCP. Why add a breaker a when all you need is an appropriately rated safety switch?
Not really; you can't be exposed to live parts when operating a disconnect that needs to be readily accessible.That should be compliant, right?

1) In this particular build, there needs to be two separately controllable disconnects. The cleanest way I have found to do that is to use the Din rail breakers.Why add a breaker a when all you need is an appropriately rated safety switch?
what is your voltage?1) In this particular build, there needs to be two separately controllable disconnects. The cleanest way I have found to do that is to use the Din rail breakers.
2) The cost of properly rated switches is typically higher than the cost of the breakers.
Temperature adjusted it is just under 200Vwhat is your voltage?
In that application we use a few dozen of these a year. No problem passing inspection ever. $27Temperature adjusted it is just under 200V
If you hunt around, you can find the IMO for 72 bucks x 2= 144 bucks1) In this particular build, there needs to be two separately controllable disconnects. The cleanest way I have found to do that is to use the Din rail breakers.

That is indoor rated, the NEMA outdoor rated is higher.In that application we use a few dozen of these a year. No problem passing inspection ever. $27

Make a great addition to your electrical room by choosing this excellent Siemens General Duty 2-Pole 2-Wire Non-Fusible Indoor Safety Switch. Horsepower rated.www.homedepot.com
Trust me, it's the same one. Some sort oddness with HD website. As I said.... $27 rated for outside, passed inspection dozens of times with it outside already.That is indoor rated, the NEMA outdoor rated is higher.

UL requirement. The only other approach is calling it an "industrial control panel", but that raises other issues.Where does it say that?
