Which step in the troubleshooting flowchart requires the use of personal protective equipment (PPE) due to electric hazards?

Using personal protective equipment (PPE) is essential when engaging in activities that present electric hazards. Testing the unit with an EVSE (Electric Vehicle Supply Equipment) simulator involves working directly with electrical components and systems that can pose significant risks. The simulator is designed to create conditions that mimic real charging scenarios, which can expose a technician to high voltages or currents.

During this step, technicians may be handling potentially live circuits, requiring appropriate PPE such as gloves, goggles, and insulating tools to protect against electric shock or arc flash. This safety gear helps reduce the risk of injury in what could be a hazardous environment.

In contrast, visually inspecting the EVSE, checking the power supply, and logging diagnoses typically do not involve direct interaction with electrical current or components in a way that would necessitate the same level of protective gear. While it is always advisable to exercise caution and follow safety protocols in electrical work, the specific need for PPE is heightened during testing processes that simulate active electrical conditions, making it essential in this case.
