What is indicated by 'properly grounded' lines or equipment?

The term 'properly grounded' lines or equipment refers to a crucial safety practice in electrical systems. Grounding provides a low-resistance path for electrical current to flow safely into the earth in the event of a fault. This significantly reduces the risk of electric shock to individuals working on or near conductive materials that could become energized.

When equipment is properly grounded, it helps to ensure that in the case of insulation failure, the electrical current will not pass through a person, but rather through the grounding system. This protective measure is essential in creating a safer working environment and helps reduce the likelihood of serious injuries or fatalities caused by electric shock.

While grounding increases safety by mitigating shock risks, it does not guarantee complete safety or the absence of all hazards. Workers should always follow additional safety protocols and practices to ensure comprehensive safety in the workplace.
