What does a properly installed grounding conductor have to effectively reduce current passing through the body?

A properly installed grounding conductor must have low resistance to effectively reduce current passing through the body. The primary purpose of a grounding conductor is to provide a low-resistance path for electrical current to travel safely into the ground in the event of a fault. When an electrical fault occurs, such as a short circuit or equipment failure, a low-resistance pathway ensures that the current has a route with minimal opposition, thus preventing dangerous levels of current from passing through a person's body.

A low-resistance grounding system minimizes the voltage difference that can develop across the body and allows fault current to be redirected and dissipated into the ground instead of flowing through individuals who may come into contact with the electrical equipment. This reduces the risk of electric shock, making the electrical system safer for both workers and the public.
