Which equipment is used to create a low impedance path for short circuit current?

• A. Insulated tools
• B. Circuit breakers
• C. Personal protective grounds
• D. Transformers

Answer: (C)

Creating a low impedance path for short circuit current is critical for ensuring safety and proper operation of electrical systems during fault conditions. The correct answer involves taking steps to ground the electrical conductors, which is essential for protecting both equipment and personnel. Personal protective grounds are specifically designed to provide a safe, low-resistance connection to earth. This connection ensures that in the event of a short circuit, the fault current is directed safely away from the employees and equipment, minimizing potential hazards such as electric shock or fire. By using personal protective grounds, workers can confidently perform maintenance or repairs on electrical systems without the risk of encountering hazardous voltages, effectively safeguarding their safety against unexpected faults. On the other hand, insulated tools, while essential for providing safety during electrical work, do not create a pathway for fault currents. Circuit breakers are protective devices that interrupt the flow of current under fault conditions but do not create a low impedance path per se. Transformers are used for voltage transformation and do not function as grounding mechanisms to manage short circuit currents.
