Find the right AWG wire size quickly, review safety-oriented installation assumptions, and tune advanced phase/material/environment inputs with voltage-drop...
Start in Simple mode with voltage, current, and run length. Heavier loads and longer distances need thicker wire (lower AWG number). Use Safety Review/Advanced modes for installation and environment assumptions.
A common NEC guideline is 3% for branch circuits and 5% combined for feeder + branch. Safety Review mode includes quick 3%/5% targets so you can test both scenarios quickly.
