What requirement must service-drop conductors meet?

Service-drop conductors are critical components of electrical distribution and must meet specific requirements to ensure safety and reliability. The correct answer indicates that these conductors must be both grounded and insulated.

Grounding is essential for enhancing safety by providing a path for fault currents, which helps to prevent electrical shocks and reduces the risk of fire. Insulation, on the other hand, is crucial for protecting the conductors from environmental factors such as moisture and physical damage, as well as preventing unintended contact with conductive materials or surfaces.

Together, grounding and insulation for service-drop conductors help ensure they function properly in various conditions, mitigating potential hazards associated with electrical systems. Thus, meeting both requirements is vital for the safe operation of electrical service systems.
