What are the parts of an electrical system called that isolate conductive material from other parts?

The parts of an electrical system that isolate conductive materials from other components are known as insulators. Insulators serve a critical function by preventing the flow of electric current to unwanted areas, thus ensuring safety and efficiency in electrical systems.

For instance, materials such as rubber, glass, and certain plastics are commonly used as insulators because they do not conduct electricity. This property allows them to protect users from electric shock and to maintain the integrity of the electrical circuit.

In contrast, conductors are materials that allow the flow of electric current, connectors serve to join electrical components securely, and arrangers are not a standard term in electrical terminology. Understanding these distinctions underscores the vital role insulators play in protecting and maintaining the safety of electrical systems.
