What is the primary role of insulation in electrical safety standards?

The primary role of insulation in electrical safety standards is to minimize the risk of electric shock and fires. Insulation serves as a protective barrier that prevents the unintentional flow of electrical current to areas where it could cause harm to people or property. By isolating conductive materials, insulation helps ensure that electrical circuits operate safely. This reduces the likelihood of short circuits, which can lead to overheating and potential fires, thus promoting overall electrical safety. Insulating materials are specifically designed to withstand high voltages and temperatures, ensuring that they effectively protect against electrical hazards.

While factors like electrical resistance, aesthetics, and heat generation can play roles in electrical systems, they are secondary to the critical function of insulation in safeguarding against electrical hazards.
