Checks with no short

Rules of thumb: cable ratings 22 AWG ≈ 3 A, 20 ≈ 5 A, 18 ≈ 7 A, 16 ≈ 10 A, 14 ≈ 15 A, 12 ≈ 20 A. Typical ATO/ATM blade-fuse curve. PSU behaviour from Mean Well LRS datasheets. Controller limits are editable assumptions. A teaching model, not a substitute for your parts' datasheets.
