Stop Guessing.
Start Building.
The all-in-one digital toolbox for contractors. Perform NEC-compliant load calculations, voltage drop, and conduit fill instantly—from residential service calls to commercial projects.
Residential Load
Standard Method residential load calc. SABC, Laundry, HVAC & Range logic built-in (NEC 220).
Voltage Drop
Determine efficiency for long runs. Calculate percentage loss and end-of-line voltage.
Conduit Fill
Dynamic fill calculator with auto-upsizing logic. Mix different wire types and sizes.
Built for the Site Foreman.
Most calculators are too simple for the job site, or too complex to use on a phone. MelynCalc bridges that gap. We provide the granular control needed for commercial work with an interface simple enough for a first-year apprentice.
Commercial Grade
Handles 3-Phase, diverse loads, and complex fills.
Code Compliant
Directly references NEC Tables (Ch 9, Art 220, etc).
