5. What is the maximum voltage drop allowed by NEC recommendations for branch circuits in commercial buildings? → 3%
6. A maintenance technician is about to work on a 480V electrical panel. Which minimum PPE is required? → Arc flash suit, face shield, and insulated gloves rated for the voltage
7. A circuit breaker keeps tripping repeatedly. What should you investigate? → Investigate the circuit for overloads, short circuits, or ground faults
8. Which of the following is an example of a reportable OSHA recordable incident? → A sprained wrist requiring prescription medication
9. Which type of defrost system uses hot refrigerant gas from the compressor discharge to melt evaporator frost? → Hot gas defrost
10. In a store's electrical panel, what does a 'double-pole' breaker control? → A single 240V circuit
11. What is the correct sequence for applying joint compound when finishing a drywall seam in a Walmart retail area? → Tape coat → finish coat → topping coat
