Why is it necessary to use insulated tools when working on electrical systems?

Using insulated tools when working on electrical systems is crucial for protecting against electrical shock. The insulation on these tools is specifically designed to prevent electrical current from passing through the handle and into the body of the electrician. This is especially important when working with live circuits or in environments where the risk of contact with energized components is high.

In electrical work, even low voltage can be dangerous if handled improperly, and insulated tools provide a critical layer of safety by ensuring that the user is not at risk of accidental electric shock. By using tools that are rated for the voltage levels they might encounter, electricians can significantly reduce the likelihood of injury while performing their tasks.

This focus on safety is fundamental in electrical training and practice, as protecting workers from potential hazards is paramount in the field.
