What is the primary role of insulation in electrical wiring?

The primary role of insulation in electrical wiring is to prevent electrical shock and short circuits. Insulation is the protective layer that surrounds conductive materials, such as copper wires, isolating them from one another and from external surfaces. This protective barrier ensures that the electrical current flows only within the intended pathway, minimizing the risk of accidental contact with live wires that could lead to injury or death from electric shock. Additionally, insulation helps to prevent short circuits, which occur when there is an unintended connection between two conductive paths, potentially causing damage, fires, or equipment failure.

Insulation materials are specifically designed to withstand various environmental conditions, including moisture, heat, and abrasion, further enhancing safety and reliability in electrical systems. By fulfilling this crucial role, the insulation ensures the safe operation of electrical devices and systems.
