Wire & Load vs Vexten

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.

Vexten is the most advanced electrical engineering suite, designed to bring the power of professional desktop software directly to your mobile device. Whether you are a field technician, inspector, student, or project engineer, Vexten provides all the necessary tools to design, audit, and optimize electrical installations with millimeter precision and strict adherence to current standards. Best of all: Vexten works 100% offline. Forget about simple, isolated electrical formula calculators. Vexten is a comprehensive electrical design engine, structured into three main sections: 1. ELECTRICAL INSTALLATION DESIGN AND OPTIMIZATION Create the complete hierarchy of an electrical project, from the main service entrance to the final branch circuits. The engine executes thousands of simultaneous calculations in a fraction of a second: Phasor Load Balancing: We do not use simple arithmetic averages. The engine performs real vector (phasor) sums—taking into account power factors, load types, and phase shifts—evaluating millions of combinations to calculate the optimal phase balance for your panelboard. Cascaded Protection Optimization: The system reviews the entire hierarchy (upstream and downstream), guaranteeing correct ampacity and selectivity. This ensures that a fault in a minor branch circuit does not trip the building's main breaker. Automated Calculations: Voltage drop, conductor sizing (copper/aluminum), conduit fill, short-circuit currents (Isc), and grounding systems. Technical PDF Reports: Export highly detailed technical reports, including load schedules and engineering parameters, ready to be presented to clients or authorities. 2. FIELD INSPECTIONS AND AUDITS Transform your smartphone into a professional audit center for your job sites: Capture photos of electrical panels or faulty installations directly within the app. Use the integrated Markup Editor to draw arrows, circles, or notes directly on the image to highlight anomalies. Document defects, assign severity levels, and propose formal technical corrective actions. Generate a Technical Inspection PDF Report, featuring a global risk assessment, annotated photos, and violated standards—perfect for professionalizing your workflow. 3. CATEGORIZED CALCULATORS AND TOOLS Over 350 mathematical formulas programmed from scratch, organized into 134 tools across 10 key categories: Conductors and Raceways. Protections and Electric Motors. Transformers and Industrial Heating. Lighting, Electronics, and Unit Converters. Renewable Energy (Photovoltaic and battery sizing). - KEY FEATURES - 100% Offline (Local-First): Design and calculate in basements, mines, or remote areas without network coverage. Your projects and photos are stored exclusively on your device's local memory, ensuring maximum speed and total privacy. International Standards: Integrates over 45 digitized reference tables based on the NEC (National Electrical Code) and the IEC (International Electrotechnical Commission), applicable to standards in over 170 countries. Intelligent Recommendations: The system acts as a digital auditor. If you choose a configuration that violates safety standards, the app issues technical alerts and guides you toward a compliant solution. Legal Disclaimer: Vexten is a technical assistance tool. The results are provided for guidance and do not replace the professional judgment, review, or signature of a certified engineer or technician. Always independently verify all calculations according to local electrical codes before any practical implementation on site.
