What safety precautions should be taken when working with live circuits?

The practice of ensuring all circuits are powered down is critical for safety when working with live circuits. This precaution significantly reduces the risk of electric shock, which can be life-threatening. By powering down the circuit, you eliminate the potential for current to flow, allowing for safe inspection, maintenance, or installation of electrical components.

In addition to this primary safety measure, other precautions can also enhance safety when dealing with electricity, such as using rubber gloves or wearing safety goggles. However, nothing is more effective at preventing electrical accidents than ensuring that all circuits are completely de-energized before beginning work. Working during daylight is not a recognized safety standard specifically related to electric shock prevention and does not address the primary risks associated with live circuits. Overall, powering down circuits establishes a foundational safety practice in electrical work.
