For everyday field calculations (wire sizing, voltage drop, conduit fill, box fill), you can switch immediately — SparkShift is free and requires no installation. For formal engineering design submissions with multi-panel reports, SparkShift Pro's export features cover many scenarios, though dedicated design software may still be preferable for large commercial projects.
SparkShift's dwelling load and commercial load calculators use NEC standard and optional methods per Articles 220 and 120. For residential service sizing and standard commercial loads, results should match. Electrc may offer more granular inputs for complex multi-panel engineering scenarios.
SparkShift Pro exports calculation results as PDF reports. For AHJ submission, the format and level of detail should be confirmed with your local authority.
Yes. SparkShift Pro subscribers can export calculation results as PDF reports suitable for project documentation.
