I'm building a circuit to feed about 200 feet (non-linear) of LED lighting. These are 24V LEDs, with each 16 foot roll consuming 72 watts DC. I want to size my power supply to handle the entire installation at full brightness, which is about 38 amps. In reality, the installation would only be running at about half brightness.
I have two 20A and two 15A feeds available at the panel. In my mind, the most logical (and safest) option would be to halve the installation and use two power supplies and the 20A feeds to power each half.
I was told I could use one power supply and balance the current over the two 20A feeds (assuming both circuits were on the same leg), however I don't believe that's safe.
Edit: I've included additional information about the setup.
Below is a simple schematic of what I'm looking to achieve. Note that I left out data signal wiring to simplify the schematic, as I'm just interested in powering the LEDs for now:
For power, I'd was looking at something like a Mean Well 600W 24V 25A AC/DC Switching Power Supply
