Electric Master vs SwiftPanel

Every answer names the code table it came from — 310.16, Chapter 9, 250.122, Article 220 — so you can check it, cite it to an inspector, and learn it. That is the whole point. 20 calculators and a full panel planner. All of it works with no signal, in a basement, on a roof, in a crawlspace. PANEL PLANNER + PANEL SCHEDULE Lay out the actual board on screen. Drag breakers, GFCI/AFCI devices, busbars and terminals onto the rail, wire them up, name every circuit. Then export a PDF with your logo: panel schedule, board drawing and a parts list, ready to hand over.
