If you work on energized circuits, what is the safest practice?

The safest practice when working on energized circuits is to de-energize all circuits whenever possible, regardless of voltage. This is because working on de-energized circuits significantly eliminates risks associated with electrical shock, arc flash, or accidental contact with live components. De-energizing not only protects the worker but also gives them the opportunity to properly inspect and maintain the equipment without the constant threat of electrical hazards.

While wearing insulated gloves, using one hand only, and ensuring a ground connection are all important precautions to take when it’s absolutely necessary to work on energized circuits, they do not eliminate risk as effectively as de-energizing. These practices may reduce the chances of injury, but they do not provide the complete safety that comes from turning off the power. Therefore, prioritizing de-energization when feasible is the best and safest approach in electrical work.
