Electrical panel: circuit directory and mapping

Turn a poorly labelled panel into a reliable map of circuits, critical loads and shutoffs without opening or altering energized parts.

VERT / GREEN = documenter/entretenir · JAUNE / YELLOW = mesurer/vérifier · ROUGE / RED = arrêter et faire valider.

Labels vague/wrong
Methodically test circuits from accessible loads and correct directory. Unknown breaker feeds critical equipment
Identify before work or planned shutdown. Panel cover must be removed
Stop DIY; leave panel work to the authorized professional. Circuit map current
Keep a copy in My Home and near panel without sensitive data.

What the professional checks

Identify circuits/loads and correct abnormalities
Verify panels/circuits under jurisdiction rules
