D) circuit protective conductor.

Question

Quizplus · Accepted Answer

Earthing is the act of connecting the exposed conductive parts of the installation to the main earthing terminal of the installation. Choice A (earth) is incorrect as it refers to the physical ground rather than the act of connecting to it. Choice C (bonding conductor) is a conductor used to connect two or more metallic parts of the installation to ensure they are at the same potential. Choice D (circuit protective conductor) is a conductor used to provide a path for fault current to flow in order to trip the protective device (e.g. circuit breaker) and disconnect the supply. While important for safety reasons, it is not directly related to the act of connecting to the main earthing terminal.
