Tabular numbers don't jump. Errors stay inline, never as pop-ups. Voltage-drop, wire-size, and bending results all carry their NEC chapter sources, because the right answer also needs the receipt. — Disclaimer — Electrician Field Kit is a calculation and reference tool to assist licensed electricians and apprentices. All results are produced from formulas and tables derived from publicly available NEC standards. The app is not a substitute for professional engineering judgment, jurisdictional code interpretation, or inspection by an authority having jurisdiction.
