Why should the test leads of a "megger" NEVER be touched by anyone when in use?

The test leads of a "megohmmeter" or megger should never be touched by anyone while in use because it could result in an electrical shock. A megger is used to test the insulation resistance of electrical equipment and wiring by applying a high voltage to the circuit being tested. This high voltage can be hazardous, and coming into contact with the test leads during operation poses a serious risk of electric shock. The purpose of the megger is to measure insulation integrity, and while it performs this function, any direct contact with its leads could expose a person to potentially dangerous voltage levels. Safety is paramount when working with electrical testing equipment, and understanding the risks associated with using a megger is critical for maintaining a safe working environment.
