Performance Tasks
Under the supervision of the instructor, the trainee should be able to do the following:
1. For a residential dwelling of a given size, and equipped with a given list of major appliances, demonstrate or explain how to:
• Compute lighting, small appliance, and laundry loads.
• Compute the loads for large appliances.
• Determine the number of branch circuits required.
• Size and select the service-entrance equipment (conductors, panelboard, and protective devices).
2. Using an unlabeled diagram of a panelboard (Performance Profile Sheet 3), label the lettered components.
3. Select the proper type and size outlet box needed for a given set of wiring conditions.
