As the water touched the terminal, a fault current escaped. Because the grounding was inadequate (high resistance), the standard overcurrent breaker didn't "see" the fault as a short circuit. It remained closed.

: This is the "shield" of the standard. It details measures for protection against electric shock (using techniques like automatic disconnection of supply), thermal effects, and voltage disturbances. Part 5: Selection and Erection of Electrical Equipment As the water touched the terminal, a fault current escaped
In Europe, this standard is published by CENELEC as , influencing national regulations like the UK's BS 7671. It covers everything from residential wiring to complex industrial installations. Core Parts of the IEC 60364 Series Demystifying IEC 60364: The Global Blueprint for Electrical
IEC 60364 is a series of standards for electrical installations in buildings, published by the International Electrotechnical Commission (IEC). The standard provides guidelines for the design, installation, and verification of electrical installations in buildings, including residential, commercial, and industrial premises.
IEC 60364, titled Electrical Installations for Buildings , is a multi-part international standard. It establishes fundamental principles, requirements, and technical guidelines to ensure the safety of persons, livestock, and property against hazards arising from the use of electricity. It covers risks such as electrical shock, thermal effects, overcurrent, fault currents, and voltage disturbances.
