According to Article 230, why must service conductors be protected from physical damage?

Service conductors must be protected from physical damage primarily to ensure reliability and safety of electrical systems. These conductors are crucial components that deliver electricity from the utility company's distribution system to the electrical system of a building. If service conductors are subject to physical damage, it can lead to disruptions in power supply, potential electrical hazards, or even fires, putting both the property and the occupants at risk.

Protecting these conductors ultimately helps maintain the integrity of the electrical system, ensuring that it operates safely and effectively under various conditions. Without adequate protection, service conductors could be exposed to environmental factors, mechanical impacts, or other risks that could compromise their functionality and safety. This adherence to safety standards reflects the intent of NEC Article 230, which aims to mitigate risks associated with electricity and promote safe installations.
