I have a power supply that outputs just over 13A @ 24VDC - decidedly not CL2.
My desire is to break that 24VDC output into (5) 2A circuits, each protected with a 2A fast-acting fuse (48W of available power per circuit). Would this approach allow a "non-inherently limited" PS to supply Class 2 circuits? The fuses would of course be immediately adjacent to the power supply, and in the same enclosure.
My research seems to indicate that fusing is an acceptable approach, but at the same time it's unclear. Article 725 is also strangely silent on that approach.
I unfortunately don't have the room to use a separate CL2 rated supply for each run, otherwise I'd consider that approach.
I need to draw approximately 1.1A per circuit, and each run will be done with CL2 rated 16AWG cable.
Thoughts?
