Should you ground a DC power supply?
A:Yes, in many cases, it is necessary to ground a DC power supply. Grounding helps to improve safety by preventing electric shock in case of insulation failure. It also helps to reduce electromagnetic interference and stabilize the electrical potential of the power supply, which is beneficial for the proper operation of electronic devices. However, there are some specific low - voltage and isolated DC power supplies that may not require grounding depending on the application and safety regulations.
