Which type of wiring is typically required for equipment grounding in electrical systems?

1. Non-metallic

2. Connectorized

3. Bonded

4. Grounded

The correct answer is: Bonded

In electrical systems, grounding is essential for safety and protecting equipment from electrical faults. Equipment grounding specifically requires a type of wiring that ensures a continuous and low-resistance path to ground. The term "bonded" describes a state where conductive parts are connected together and to the grounding system to eliminate differences in voltage potential. This method effectively reduces the risk of electric shock and equipment failure by ensuring that any stray electrical currents have a safe pathway to the earth. Bonded wiring provides a reliable means of meeting regulatory and safety standards, ensuring that all conductive components are interconnected securely. This is crucial in protecting both personnel and equipment by maintaining a proper grounding system that can effectively handle fault currents. The other types of wiring mentioned do not fulfill the critical role of providing a safe and effective grounding path in electrical systems.
