However, their insulation\u2014the protective layer that prevents unwanted current leakage\u2014can degrade over time. That\u2019s where insulation resistance testing becomes essential. This critical maintenance practice helps detect issues before they lead to costly failures, ensuring safety and reliability. In this complete guide, [&hellip;]"}
