NEC Compliance Scanner — Snap a photo of any electrical installation and get instant AI analysis identifying potential NEC violations, severity ratings, code references, and recommended fixes.
Professional Calculators
Conduit Bending — 90° bends, offsets, kicks, saddles, and back-to-back calculations for EMT, IMC, and RMC with full deduction tables.
Voltage Drop — Calculate voltage drop percentage for any wire size, distance, and load with NEC 3% compliance checking.
Box Fill — NEC 314.16 compliant calculations for conductors, devices, clamps, and grounds.
Breaker Sizing — Automatic 125% continuous load calculations with wire size recommendations.
3-Phase Power — kW, kVA, and current calculations with adjustable power factor.
Transformer — Primary and secondary current calculations for both single-phase and 3-phase systems.
Ohm's Law — Solve for voltage, current, resistance, or power with common field values.
Wire Ampacity — Complete NEC Table 310.16 reference for 75°C copper conductors.
Reference Library
Electrical formulas, conduit fill tables, motor FLC and LRA data, wire torque specifications, bolt torque specifications, and business resources for running your shop.

What’s new
Better NEC answers. The code assistant now pulls from the full
2017 code text, so you get real section numbers and real values
instead of general guidance.
Wire ampacity table now covers 60C, 75C and 90C for both copper
and aluminum, out to 1000 kcmil, and follows your saved settings.
Breaker and 3-phase calculators now open on your default voltage.
Fixed the share links so referral codes actually work.
