DC Power Distribution

The standard outlet used to be the 6-15.
Because it was not normally used in AC systems.

That is pretty commonly used for 240 volt, 15 amp AC outlets. I have no idea why since if you are going to run a dedicated circuit for an AC, why not go with the 20 amp version of the 240 volt receptacle.

That's why it's not a commonly used outlet.
Nobody installs 240v 15a circuits.

I have a similar issue. I want to provide a 12V DC light on my 48V battery system, so I do not have to run my inverter just for a light.


I can find various 12V, primarily landscape lights that meet my need. Said lights are UL 2108 when used with a paired class 2 AC->DC power supply.


But that is not what I want to do, as I want DC only.


I found this:

DDR-120C-12 in this case.

This gives me what I want, but it is not a class 2 power supply, as it is 120W, max 100 for class 2. But it is UL 62368 as a standalone voltage reducing power supply. (UR).

So, do I just use this, using chapter 3 wiring methods (wire in conduit, etc) a DC fuse, and call it a day?

I want to remain in NEC 2020.
