In terms of electrical safety, what does a leak current greater than 20mA signify?

A leakage current greater than 20mA indicates a potential hazard. When electrical devices or systems experience leakage current, it represents an unintended flow of electricity that could pose risks to personnel and equipment. A current at this level suggests that there may be insulation failure, equipment malfunction, or other issues that could lead to electric shocks or fire hazards.

In a safe working environment, leakage currents typically need to be well below this threshold to ensure safe handling and operation of electrical equipment. Thus, a current exceeding 20mA should prompt immediate investigation and rectification to mitigate any risks associated with electrical safety, ensuring compliance with established safety standards.
