It is important for a technician to _________________ the power when working on 120 VAC systems.

Turning off the power when working on 120 VAC systems is crucial for several reasons. First and foremost, safety is the primary concern. High voltage systems can pose serious hazards, including the risk of electric shock or electrocution. By ensuring that power is completely turned off, technicians can work on the systems without the constant danger of live electricity.

Additionally, turning off the power prevents short circuits and avoids potential damage to the RV’s electrical systems or components. It also allows technicians to perform maintenance and repairs with confidence, knowing that any tools or equipment they use will not inadvertently create a dangerous situation.

Some technicians might consider analyzing or monitoring power levels while working on an electrical system. However, these actions can still pose risks if the system is live. Diverting or increasing power are not appropriate actions when servicing electrical systems, as they could lead to electrical faults or systems not functioning as intended. Ensuring that the power is turned off provides a safe working environment and is an essential practice for anyone servicing 120 VAC systems in RVs.
