If the grounding impedance device is not required to be installed in series, what implications does that have?

When grounding impedance devices are not required to be installed in series, it can lead to potential safety hazards. This means that if the grounding system is not configured correctly by using these devices in series, it might not effectively limit fault currents as intended. Without proper grounding, there are risks of electrical shock, equipment damage, and increased chances of fire hazards due to uncontrolled fault currents.

The function of a grounding impedance device is to manage the flow of current during fault conditions. If the device is not installed as needed, the grounding system may fail to provide the necessary protection. This could compromise the safety of both personnel and equipment, thereby resulting in significant risks in electrical installations.
