When testing electrical components, what should be done to ensure safety?

To ensure safety when testing electrical components, disconnecting power and discharging any capacitors is essential. This step protects the technician from electric shock, as working on live circuits can lead to serious injuries or fatalities. Capacitors can store a significant charge even after the power is turned off, and failing to discharge them can result in unexpected electrical discharges.

By disconnecting the power, the technician ensures that there’s no live voltage present, significantly reducing the risk associated with testing and working on electrical components. Additionally, discharging capacitors removes this stored energy, further enhancing safety during the test procedure.

This approach emphasizes the importance of following established safety protocols, which is critical in preventing accidents and ensuring a safe work environment when dealing with electrical systems.
