Electric equipment must be what to ensure safety?

Grounding electric equipment is crucial for safety because it establishes a low-resistance path that directs any fault current safely into the ground. This is essential in preventing electric shock, equipment damage, and potential fires in the event of a short circuit or equipment failure. When electrical equipment is grounded, it minimizes the risk of an electric shock to operators and users, as it safely disperses excess electrical energy away from the equipment housing.

In addition to the grounding function, grounding helps stabilize the voltage levels in the system, reducing the likelihood of voltage spikes that can harm sensitive electronic components. Overall, grounding is a fundamental aspect of ensuring that electric equipment operates safely and reliably in various environments.
