Electrical Calculation Tools
How it works
1
Select Your NEC Edition
Choose the code year your AHJ enforces — 2017, 2020, 2023, or 2026. Every calculation uses the correct tables and article numbers for that edition.
2
Run Your Calculation
Voltage drop, wire sizing, load calc, conduit fill, or OCPD — enter circuit parameters and get the answer with the full NEC derivation and controlling factors.
3
Organize by Project
Group calculations by job, panel, or feeder. Track every circuit across the project from bid through final inspection.
4
Export for the Permit Office
Generate a permit-ready PDF with calculation sheets, NEC references, and a summary table — formatted for the inspector, not the engineer.
