Type TC power and control cable may be used ___.

• A. as open cable on brackets
• B. where exposed to physical damage
• C. none of these
• D. in outdoor locations when supported by a messenger cable

Answer: (D)

Type TC cable is designed for use in outdoor locations only when it is properly supported. The correct way to run it outdoors is to have a separate messenger cable that provides the support, keeping the TC cable off surfaces and protected from movement and damage. This method meets NEC requirements for outdoor installations by ensuring adequate mechanical support and minimizing exposure to potential damage. Using TC cable open on brackets or in places where it could be damaged would not meet those installation standards, so outdoor use with a messenger is the appropriate configuration.
