What is the main purpose of using insulated tools in electrical work?

Insulated tools are primarily designed to provide protection from electric shock. The insulation around the handles of the tools acts as a barrier, preventing electrical current from passing through to the user. This is crucial in electrical work, where the risk of coming into contact with live wires or other energized components is inherent. The insulation is tested to specific voltage ratings, ensuring that when used properly, the tools help safeguard the technician from potential electrical hazards while performing tasks such as wiring, circuit testing, or equipment installation.

Using insulated tools enhances safety by significantly reducing the likelihood of electric shock, which can result in serious injury or fatality. While improving dexterity, preventing accidental short circuits, and ensuring faster connectivity might have their merits in different contexts, the primary and most critical function of insulated tools is the protection against electric shock for anyone working with or near electrical systems.
