Independent Electrical Contractors (IEC) 212 Practice Exam

In a panel schedule, the essential purpose is to identify each circuit’s function, its protection, and the load it carries. The description of the circuit tells you what the circuit controls (for example, kitchen outlets or lighting in a specific area), the breaker size shows the protective device rating that will trip if the current is too high, and the connected load indicates the amount of electrical demand served by that circuit for planning and safety checks. Together, this trio lets technicians quickly locate circuits, verify proper protection, and assess capacity or plan future changes without guessing. Items like date of inspection, panel color, or room designation aren’t part of the circuit map itself—they’re separate details that aren’t needed to identify or protect the circuits on the schedule.
