Which remedy is not allowed to stop objectionable current over an electrical system?

Using the earth as the ground-fault current path is not an acceptable remedy to stop objectionable current over an electrical system because it presents significant safety hazards. Ground fault currents should be managed through proper grounding and bonding methods. Utilizing the earth directly can lead to unsafe situations, including potential for electric shock and equipment damage.

Ground faults are intended to be directed to a suitable grounding system that ensures unwanted current is safely dissipated. The purpose of grounding is to provide a direct path for fault currents to safely return to the earth, but relying on the earth itself alone — without the proper system in place — fails to effectively manage the risk of fault conditions and creates potential safety issues.

In contrast, options such as installing a larger circuit breaker, reducing the load on the system, and isolating the faulty equipment are all proactive measures aimed at handling objectionable current appropriately by preventing overloads, ensuring safe operation, and fixing or excluding faulty components from the circuit. These methods maintain the integrity of the electrical system and help prevent dangerous conditions from arising.
