What is the status of unsupported cable assemblies in crawlspaces?

Unsupported cable assemblies in crawlspaces are not acceptable due to the inherent risks they pose. When cables are not properly supported, they can sag or become strained over time, leading to potential damage and safety hazards such as electrical shorts or fires. The National Electrical Code (NEC) mandates that all electrical conductors be properly supported to maintain the integrity of the electrical system and ensure safety. This means that cables should be secured to prevent movement and potential damage, especially in areas like crawlspaces where environmental conditions can include moisture and temperature fluctuations. Proper support also helps in maintaining access for future inspections and repairs, which contributes to long-term safety and reliability. Given these considerations, unsupported cable assemblies are prohibited in crawlspaces, solidifying the understanding that safety and code compliance are paramount in electrical installations.
