Yes. SparkShift runs in any browser — just navigate to sparkshift.app/calculators. No account required to use the calculators. You can try it alongside your existing calculator immediately.
SparkShift calculations are based on official NEC tables and formulas (wire sizing from NEC 310.16, conduit fill from NEC Chapter 9, motor FLC from NEC Tables 430.247–430.250). The results should match hand calculations or any NEC-compliant tool.
SparkShift covers wire sizing, conduit fill, voltage drop, motor circuits, box fill, dwelling loads, and more — most of what ElectriCalc Pro handles. SparkShift adds conduit bending with 3D visualization, arc flash estimates, and EV charger load calculations that are not available on the hardware calculator.
Yes. SparkShift Pro subscribers can export calculation results as PDF reports. The free tier allows in-browser use with copy/paste of results.
