Electrical Code Assistant

Ask a question about the NEC or fire code and get a plain-language answer with the relevant section numbers and a worked example. Free to use — educational guidance, not a replacement for the adopted code or your AHJ.

Covers the NEC and fire code. Tucson / Pima County may amend — confirm specifics with the AHJ.
Code Assistant
Hi — ask me an electrical or fire-code question. I compute from the actual NEC tables: wire & ground sizing (Table 250.122 / 250.66), voltage drop, conduit & box fill, ampacity/derating, motor full-load current (430.248/430.250), pull-box sizing (314.28), and cord ampacity — plus GFCI/AFCI, working clearances, and more. I cite the article/section and show a worked example. Pick your code edition above; I default to the 2023 NEC.

How it works. Your question goes to an AI assistant trained on electrical and fire-code knowledge. It explains the requirement in plain language, cites the relevant NEC article/section, and works an example with numbers. It does not reproduce the copyrighted text of the NEC or fire codes — for the exact wording, read the adopted code (the NEC is available free, read-only, at nfpa.org).

Please verify. This is an educational aid, not legal or engineering advice. Code editions and local amendments vary — Tucson and Pima County may enforce a different edition or add amendments. Always confirm against your jurisdiction’s adopted code and the Authority Having Jurisdiction (AHJ). For stamped design, short-circuit / arc-flash / coordination studies, or permit documents, our electrical engineering team can help.
