Nothing is locked into a static PDF. Export clean job reports to share with an inspector or client. BUILT ON THE CODE, NOT A GUESS Key tables — Table 310.16 ampacity, conductor and conduit areas — were checked against the printed NFPA 70 (2023). Where the code doesn't list a value, the app says so instead of guessing. TRY EVERYTHING, FREE 7-day full-feature trial: every module, unlimited saved jobs, unlimited PDF exports, no watermark. After the trial, one one-time purchase unlocks everything. No ads. No subscription. No tracking. Available in English and Spanish. This app is a field reference tool and does not replace the judgment of a licensed electrician or the authority having jurisdiction (AHJ). Always verify calculations against the NEC edition adopted by your local jurisdiction. Not affiliated with or endorsed by NFPA.
