What can happen if insulation resistance is too low in electrical wiring?

When insulation resistance in electrical wiring is too low, it poses an increased risk of electrical shock. This is because low insulation resistance indicates that current can flow through unintended paths, such as through the human body, especially when someone comes into contact with exposed or faulty conductors. Proper insulation is designed to prevent such leakage currents and ensure that the electrical system operates safely. If the insulation deteriorates, it may not effectively prevent current from escaping the intended pathway, leading to hazardous situations where individuals can receive potentially fatal electrical shocks.

In contrast, improved efficiency, enhanced power delivery, and stable circuit operation are aspects that benefit from proper insulation. Low insulation resistance undermines these benefits and significantly increases safety risks in electrical installations.
