Electrical Code Filing Guide

Use this folder for verbatim code-book excerpts and implementation-facing filing notes.

Filing Rules

  • Create one markdown file per closely related section set, grouped by code book, edition, article, and topic.
  • Keep verbatim code language separate from implementation notes. Exact text goes in the section file; interpretation belongs in sizing docs or code comments.
  • Use a path structure like docs/electrical-code/<code-book>-<edition>/article-<article>/<sections>-<topic>.md.
  • Start each filing with the source metadata:
  • code book and edition
  • article and section numbers covered
  • why the excerpt matters to the product
  • any image or scan identifiers supplied with the source material
  • Preserve the user-supplied wording exactly when asked to file exact language. Do not silently normalize punctuation or rewrite prose.
  • If a formula image is supplied separately, note the image identifier and describe where it belongs in the section.
  • When implementation depends on the excerpt, add a short "Implementation impact" section at the end that points to the relevant code paths, but do not mix that commentary into the verbatim text.

Cross-Referencing

  • Link sizing docs to the filed excerpt rather than duplicating long verbatim code blocks.
  • Add concise reminders in repo-level AGENTS.md when a code rule is easy to misapply.
