FreeSpark AI is a field-ready NEC reference assistant built into SparkConnect Tools. Ask where the neutral goes, which circuits need GFCI, how to run a subpanel — and get an answer with the NEC article right there.
No search button. Results appear as you type, instantly pulling relevant NEC topics.
Every response shows the NEC article it's based on. You always know where the answer comes from.
When Spark AI finds a relevant calculation, one tap opens the exact calculator with your values pre-filled.
Covers GFCI wiring, standard outlet wiring, subpanel setup, 3-way switches, and GFCI vs. AFCI selection.
Reference tool only. Always verify with your adopted NEC edition, local AHJ, and qualified supervision.
Whether you're pulling wire on your first job or running your own crew, SparkConnect Tools has something for you.
Daily code questions build your knowledge. Code Quiz helps you study for licensing exams. Spark AI answers questions you'd be embarrassed to ask on the job site.
Fast bending calcs, conduit fill checks, and voltage drop in the field. No more guessing or hunting through code books mid-job.
Material estimates, job cam for site documentation, and a reference tool your whole crew can use — free on their own devices.

SparkConnect Tools provides calculations and NEC code references for field planning and educational purposes only. All calculations, code citations, wire sizing, and AI-generated responses must be verified with your currently adopted NEC edition (NFPA 70), local Authority Having Jurisdiction (AHJ), manufacturer instructions, and qualified supervision before any installation. NEC article numbers are cited for reference; this app does not reproduce NEC code text. Always obtain required permits and inspections. SparkConnect Tools does not replace professional judgment, engineering review, or licensed supervision.
