Are conductors, raceways, and cables required to be protected where subject to physical damage?

Conductors, raceways, and cables must be protected where they are subject to physical damage in order to ensure safety and compliance with electrical codes. This requirement is grounded in the principle that exposing these components to potential hazards can lead to failures, electrical shorts, or even fire hazards.

Physical damage can come from various sources such as impact from tools, vehicles, or environmental elements. By implementing protection measures, it mitigates the risk of these components being compromised, which could affect the overall integrity and reliability of the electrical system.

Regulatory standards outline specific criteria and types of protection that must be used, such as conduit, raceways, or other protective enclosures, depending on the environment and level of risk. This is necessary in all types of settings, not limited to commercial ones or just above ground situations.

In summary, the requirement for protection against physical damage is a standard safety practice to ensure electrical systems operate safely and efficiently.
