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- A panel with handwritten or outdated labels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.
