I am refining my PV wiring plan and need direction regarding the PV disconnect switch.
In my area, I am under 2008 NEC. No permits, no inspections, and as I understand it, no requirement for a rapid shutdown system.
I will have 2 separate array systems, 4 cables, plus ground running in 1.25" EMT with waterproof compression fittings, from the roof down to the 4 pole PV disconnect on the side of the detached garage. The EMT will then enter the garage and terminate at the dual MPPTs 6' inside the building in a steel cabinet.
It appears the go to disconnect, is the plastic enclosure, with glands, or drilled out to accept conduit fittings.
As I am running steel conduit, I don't want to put a plastic box inline, then run smaller conduit to, and from the disconnect.
Is using a steel exterior box, such as a type 3, or 3R with a DIN rail inside to mount a switch, or using a modular switch as in the photo, a common way to solve this issue, without going to the extreme of using a multi hundreds of dollars DC rated throw switch?
