What does the inspector look for at the panel to assess how branch circuits are labelled?

Circuit identification exists so that someone can shut off the right circuit quickly and confidently — during a repair, during a renovation, or during an emergency. What makes a directory useful is that it is clear and that it is accurate, and accuracy is the part that fails most often, because circuits get relabelled after work and directories rarely get updated. A neat printed index naming rooms that no longer correspond to the breakers is worse than a handwritten one that is correct, because it invites confidence. The inspector cannot verify every circuit against every load in a general inspection, but can report a directory that is missing, illegible, vague — 'lights', 'misc' — or evidently inconsistent with what was found. The reportable condition is the quality of the identification, not its format.

A directory is useful only if circuits are identified clearly and accurately, since its purpose is letting someone shut off the correct circuit. Legibility and correctness are the qualities that matter.

Panel directories must identify each circuit's purpose clearly and specifically, in a manner that is legible and durable. Vague descriptions and directories left inaccurate after alterations are common deficiencies.

Clear and Correct, Not Pretty. Handwriting is fine; 'misc' is not; and a tidy label that names the wrong room is the worst of all.

Vague entries such as 'lights', 'plugs' or 'spare' on an energised breaker are reportable. Spares in particular should be verified as actually de-energised.
