IRC Electrical Inspector Practice Exam

Equipment is considered "energized" when it is connected to a power source. This means that electrical energy is present in the equipment, making it capable of performing its intended function or potentially causing harm if interacted with improperly. The presence of energy means that the circuits are complete and the equipment could pose a risk of electrical shock or thermal injury. The other scenarios presented do not indicate that equipment is energized. For instance, when equipment is turned off, it does not have electrical energy flowing through it, hence it is not in an energized state. Grounding is a safety measure used to provide a low-resistance path for fault currents, but it does not imply that the equipment is energized. Testing equipment can involve energizing it, but the act of testing alone does not define the state of energization; rather, it depends on whether the power source is connected at that moment. Therefore, being connected to a power source is the definitive condition for equipment to be classified as energized.
