If a low-resistance grounding jumper is used with a worker, what will happen to body current during accidental energization?

Using a low-resistance grounding jumper during accidental energization ensures that the worker is connected to a path that effectively channels the fault current away from their body, which significantly reduces the risk of electric shock. In this scenario, the low-resistance grounding jumper serves to provide a reference ground that stabilizes the voltage that the worker might be exposed to. With this grounding mechanism in place, it prevents any significant body current from flowing through the individual.

By holding the body current at zero, the device essentially protects against harmful electrical potentials that could arise during such an incident. This means that if energization were to occur accidentally, the jumper minimizes the danger by ensuring that the electrical current does not pass through the worker's body, thereby protecting them from serious injury or electric shock. The grounding keeps the worker's exposure to hazardous voltage levels managed effectively, allowing for a safer working environment.
