What safety precaution should be taken before beginning any electrical work?

• A. Wear insulated gloves
• B. Check for low voltage
• C. Turn off the circuit breaker
• D. Ensure all tools are functional

Answer: (C)

Turning off the circuit breaker is an essential safety precaution before beginning any electrical work. This step is crucial because it helps to prevent electrocution and reduces the risk of electrical fires and equipment damage. By de-energizing the circuit, you ensure that no live wires are present, allowing the electrician to work safely without the threat of electric shock. While wearing insulated gloves, checking for low voltage, and ensuring tools are functional are all important practices, they do not replace the fundamental need to disconnect power from the circuit being worked on. The circuit breaker serves as the first line of defense against hazards, making it the most critical step in maintaining safety during electrical tasks.
