Stop guessing the right wire size. Wire & Load is the no-internet-needed reference every electrician and maintenance tech wants in their pocket. GET AN INSTANT RECOMMENDATION for AWG / mm² wire size, voltage drop percentage, and the matching standard circuit breaker — driven by NEC 2023 / 75°C ampacity tables and the 240.6(A) breaker series. WHAT'S INSIDE • Voltage-drop calculator — single- and three-phase, copper or aluminum • Configurable voltage-drop limit (0.5% – 10%) • NEC 240.4(B) next-size-up breaker rule applied automatically • 60°C limits for 14/12/10 AWG copper and 12/10 AWG aluminum pre-applied per NEC 240.4(D) • Continuous-load (≥ 3 hr) 1.25× multiplier toggle • Power-mode input — enter watts and power factor, the app derives the working current OFFLINE REFERENCE TABLES • AWG ↔ mm² ↔ diameter (ASTM B258) • Copper and aluminum ampacity (NEC 310.16, 75°C) • Standard breaker sizes (NEC 240.6(A)) • Motor starting inrush multipliers — DOL, star-delta, soft starter, VFD (NEMA MG-1) DESIGNED FOR THE FIELD • Works on any job site, no signal needed • Search built into every reference table • Both AWG and mm² always shown on results • Switch between metric (mm² / m) and imperial (AWG / ft) • Localized in English, Spanish, Japanese, French, German, and Portuguese PRIVACY FIRST No accounts.

Verdict
The clearest difference is ads: Wire & Load at none against 超シンプル電圧降下計算's shown. Wire & Load also leads on iOS requirement (16.6 vs 18.0). 超シンプル電圧降下計算's advantage is update cadence (daily vs every 2 months). On price, in-app purchases and device support there is nothing between them.
