Question 173Electricity & Electronics - QMED

70% to pass

When working on a high voltage circuit, you should always have another person present with you. This person should have a good working knowledge of the hazards associated with working on high voltage electrical circuits as well as the first aid techniques for treating electrical shock. What other knowledge is essential?

Adetailed knowledge of insulation dielectric strengths associated with the circuit being worked on

Bworking knowledge of the conductor ampacities associated with the circuit being worked on

Cdetailed knowledge of the insulation voltage ratings associated with circuit being worked on

Dworking knowledge of the circuit being worked on and all means of isolation and grounding

AI Explanation

The correct answer is D) working knowledge of the circuit being worked on and all means of isolation and grounding. When working on high voltage electrical circuits, it is essential to have a detailed understanding of the circuit itself, including the means to properly isolate and ground the circuit. This knowledge is crucial to ensure the safety of the personnel working on the circuit and to prevent the risk of electrical shock or other hazards. While knowledge of insulation, conductor ampacities, and voltage ratings are important, the most critical factor is having a comprehensive understanding of the circuit and the appropriate safety measures to take when working on it. The other answer choices, while related to electrical safety, do not address the fundamental requirement of understanding the specific circuit being worked on and the necessary isolation and grounding procedures.
