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. NO ACCOUNT, NO ADS - VOLTAGE DROP — branch and feeder circuits, instant 3%/5% check - AMPACITY — NEC Table 310.16 lookup, every size and insulation type - GROUND WIRE — equipment grounding conductor per 250.122 - OHM'S LAW and POWER TRIANGLE - THREE PHASE - PANEL PLANNER — free to enter and draw, core devices included MORE CALCULATORS - WIRE SIZING — the right conductor for the circuit, accounting for ampacity and temperature - CONDUIT FILL — EMT, IMC, RMC, PVC and flexible raceway - CONDUIT BENDING — 9 bend types (90°, offset, 3- and 4-point saddle, rolling offset, concentric, back-to-back, parallel offsets, matching centers), bender presets and an on-screen level - BOX FILL — junction box sizing per 314.16 - DWELLING LOAD — service sizing per Article 220 - NON-DWELLING DEMAND — commercial load calculation - SERVICE ENTRANCE — service and feeder sizing - GROUNDING ELECTRODE — per 250.66 - DERATING — temperature and conduit-fill factors - MOTOR — branch circuit protection per Article 430 - TRANSFORMER — overcurrent protection per Article 450 - FAULT CURRENT — available short-circuit current - EV CHARGER — EVSE branch circuit and load - SELECTIVITY — protective device coordination FOUR CODES, ONE APP NEC 2023 and 2026 - CEC 2024 (CSA C22.1) - BS 7671 - DIN VDE 0100. The app picks the right one for your region, and you can switch any time. Nobody else carries all four.
