## What is MasterElec?

Stop pausing your workflow for manual code lookups. TradeAI Electrical is a voice-powered assistant built for electricians that works offline. Access NEC references and professional calculators entirely by voice—no signal required.

Voice-First Interface: Ask "What's the ampacity for 3/0 copper?" and get instant answers.

100% Offline: Works in basements, job sites, anywhere—no internet needed.

NEC Reference: Grounding, GFCI/AFCI requirements, ampacity tables, and more.

Professional Calculators: Voltage Drop, Conduit Fill, Box Fill, and Grounding Sizing.

Export Ready: Bookmark sections and export calculations as PDFs.
