## What is Master Electrician?

Master Electrician puts the Code in your pocket — powered by AI that actually understands what you're asking.

Ask a code question in plain English and get accurate, cited answers referencing specific articles and sections across the code cycles. No more flipping through pages or guessing.

SPARKYCODE — AI ASSISTANT
Your on-site code expert. Ask questions like:
- "GFCI requirements for kitchen countertops?"
- "Wire sizing for a 200A residential service?"
- "Outdoor receptacle spacing rules?"

Get clear answers with references, plus notes on how requirements changed between code editions. Every answer reminds you to verify with your local AHJ.

SPARKCHECK — AI COMPLIANCE SCANNING
Snap a photo of any electrical installation and get an instant compliance analysis. The AI examines your work for potential violations, identifies the applicable code sections, and suggests specific corrections — complete with severity ratings and fix recommendations.

PROFESSIONAL CALCULATORS
Every calculator an electrician needs on the jobsite:

- Conduit Bending — offsets, saddles, 90s, back-to-back, kicks with fractional inch precision
- Voltage Drop — NEC-compliant calculations for copper and aluminum conductors
- Box Fill — conductor counts per 314.16
- Wire Ampacity — temperature-rated ampacity tables
- Ohm's Law — voltage, current, resistance, and power
- Breaker Sizing — proper overcurrent protection calculations
- 3-Phase Power — three-phase voltage, current, and power calculations
- Transformer Sizing — kVA, primary/secondary calculations

All calculators support customizable defaults for conduit type, conductor material, voltage, and wire temperature rating.

QUICK REFERENCE LIBRARY
Essential tables, formulas, references, and wiring diagrams accessible offline — no flipping through codebooks on the jobsite.
