Panel labeling playbook
Goal
Create clear, accurate panel directories that match as-built conditions.
Inputs you must know before you start
- Final circuit assignments and loads.
- Panelboard type and directory format.
- Owner or AHJ labeling expectations.
The path (in order)
- Verify each circuit's served area or load.
- Write specific, readable descriptions.
- Mark spares and future spaces clearly.
- Review the directory against as-built conditions.
This is
A quick checklist for accurate and compliant panel directories.
This is not
A full arc flash labeling or equipment signage plan.
Inspection-ready checklist
- Circuit descriptions are specific and accurate.
- Spares and future spaces labeled.
- Directory matches as-built circuits.
Worked example
A lighting panel is labeled with room-specific descriptions, spares are marked, and the directory is reviewed against final circuit testing.
