What is a standard requirement for conduit used in exposed conditions?

In exposed conditions, conduit must be grounded to ensure electrical safety and prevent potential hazards such as electrical shock or equipment damage. Grounding provides a path for fault current to return safely to the ground, reducing the risk of electrical fires and ensuring that protective devices can function effectively in the event of a fault. This is especially important in environments where the conduit may be subjected to moisture, corrosion, or other conditions that can affect its integrity and the safety of the electrical system.

While other considerations such as weatherproofing and insulation may apply in specific situations, grounding is a fundamental safety measure that addresses the risks associated with exposed electrical installations, making it a standard requirement for conduits in such conditions.
