漏电 (lòu diàn) literally means 'leaking electricity' — 漏 (lòu) means 'to leak' or 'to escape unintentionally', and 电 (diàn) means 'electricity'. Together, they refer to the unintended flow of electric current from a circuit or device to ground or another conductor, often due to damaged insulation, moisture, or faulty wiring. This phenomenon poses serious safety risks, including electric shock, fire, or equipment damage.

In everyday usage, 漏电 is commonly discussed in contexts involving home appliances, power tools, bathroom fixtures, or outdoor electrical installations — especially where water and electricity may mix. It’s a key term in electrical safety education, maintenance reports, and warning labels. While not a medical term per se, it falls under Health because its consequences directly affect human safety and well-being — inspectors, electricians, and homeowners all use this word when diagnosing hazards that could cause injury or death.
