When is it necessary to handle a power supply?

Handling a power supply is essential when it involves troubleshooting or replacing faulty components within the power supply itself or when addressing issues related to how the power supply interacts with other hardware. Choosing to handle a power supply only when absolutely necessary emphasizes caution; it ensures that the technician is avoiding unnecessary contact with components that can carry high voltage and pose a safety risk.

While there are situations like installing new hardware or performing routine maintenance where one might interact with the power supply, these actions should always be approached with an emphasis on safety and necessity. The focus on working with the power supply only when absolutely required promotes best practices in the field, safeguarding both the technician and the equipment. Such an attitude is critical as it minimizes the potential for electric shock and ensures that interventions are performed with purpose and precision.
