Cabling should be supported every ______ inches?

The correct answer is: 18"

Cabling support is critical in marine applications to prevent damage and ensure proper operation of electrical systems. The guideline of supporting cabling every 18 inches is based on best practices that help to keep the cables secure and prevent sagging, which can cause undue stress on the wiring over time. This spacing allows for adequate support without being overly restrictive, ensuring that cables can accommodate slight movements caused by waves or vibrations typical in marine environments. Proper support helps prevent wear and tear on the insulation and conductor, reducing the risk of electrical faults such as shorts or broken connections. In summary, a support interval of every 18 inches is both practical and aligned with safety standards, making it the recommended choice for maintaining the integrity of marine electrical installations.
