Information that changes the scope

  • Whether the panel is unlabeled, partially labeled, or wrong
  • The number of circuits and the age of the panel
  • Whether the work is standalone or part of other electrical work
  • Access to the rooms and outlets to be mapped
  • Any known problem circuits to document while mapping

When circuit mapping and panel labeling pay off

  • An unlabeled or mislabeled electrical panel
  • A newly purchased home with unknown circuit assignments
  • Preparing a rental or short-term rental for safe use
  • A panel with handwritten or outdated labels
  • Wanting a clear map before a renovation or a sale

What a clear estimate should address

The National Electrical Code (NEC 408.4(A)) requires every circuit in a panel to be legibly identified by its specific purpose, so an unlabeled or "misc" directory is a code finding, not only an inconvenience. Mapping identifies what each breaker controls and produces a clear, durable directory; it can also surface mislabeled, doubled-up, or problem circuits worth noting. Confirm whether a printed directory and a photo record are included, and whether any issues found are quoted separately.
