CORE NEC-BASED CALCULATIONS
Ampacity — real-world derating applied
Ambient temperature correction, rooftop exposure adjustments, terminal temperature limits (NEC 110.14(C)), conductor count effects, and continuous-load factors are applied together so results reflect actual installation conditions.
Voltage Drop — catch issues before inspection
Designed for branch circuits, feeders, and long runs using exact, code-based math to identify excessive voltage drop before it becomes a field or inspection problem.
Conduit Fill — see it before you pull
NEC Chapter 9 fill limits are applied automatically, with visual confirmation to help prevent jams, rework, and failed installs.
