How to use this companion

This companion is organized two ways:

  • Wrapper pages clarify a concept, scope, and common misreads.
  • Playbook pages walk through a task in order.

Each wrapper uses the same structure, including a "This is / This is not" section to reduce confusion. Each playbook includes a checklist and a worked example to make the steps concrete.

When you see NEC references, they are pointers only. Use them to locate the official language in your adopted NEC edition and any local amendments.

Recommended flow:

  1. Start with the wrapper related to the task or topic.
  2. Follow the playbook to complete the task.
  3. Review the index pages to see the same content by risk, exam focus, or article.
