In terms of electrical safety, why is it important to maintain proper insulation resistance?

Maintaining proper insulation resistance is crucial for preventing electrical shock. Insulation resistance acts as a barrier that prevents the flow of electric current to unintended paths, such as a person's body or conductive surfaces. When insulation is compromised, it can result in leakage currents that may pose serious risks of electrical shock or even fatal accidents. By ensuring adequate insulation resistance, one minimizes the risk of current passing through unintended routes, which directly contributes to safety for anyone working with or near electrical equipment.

While increasing efficiency, minimizing power loss, and enhancing component lifespan are important aspects of electrical systems, they are secondary to the primary objective of ensuring safety through proper insulation resistance.
