Why is it important to have a grounding system in conjunction with insulation?

Having a grounding system in conjunction with insulation is crucial because grounding provides a safe path for fault currents. In the event of a fault, such as a short circuit, the grounding system allows the excess electrical current to flow safely into the ground instead of through unintended paths, which can include the human body or the structure itself. This significantly minimizes the risks of electric shock and reduces the risk of fire that could occur if stray currents were to energize conductive materials or equipment.

Additionally, while insulation is essential for preventing electrical leakage and protecting conductors, it is not a fail-safe solution. Grounding acts as a secondary layer of safety, ensuring that any faults are safely handled. This synergistic relationship between insulation and grounding is key for overall electrical safety in systems to protect both people and property from the dangers associated with electrical faults.
