15 Amps at 120 Volts, Genius.  1800 Watts.

Seems that basic wattage math is beyond Feeb's understanding.

How much does your system draw?

It doesn't take much, especially when one has sweaty palms.
In any event, my recollection is that we ran my little device off of a heavier laboratory power line; I can't recall offhand if it was 240V or 208V, as we had both of those available and we didn't need to use any of the several bigger options which were present in the lab space.

A 5V power supply with that capacity could make a big spark and/or
melt some things, anyway.

  Yup.  Its why takes the OSHA safety training and fosters good lab habits, because a short would tend to ruin one's day.  Water is a big one to watch out for, because it doesn't take much dampness on one's hands to make skin a "good enough" conductor.
n any event, this was just proof-of-principle baby prototype which ran directly off of grid; the next iteration has 16x greater output & is off-grid capable, due to provisioning of an 80kW-hr Li battery pack:

But Feeb's the only real EE expert on this stuff in COLA, ya know!  /s
