What is the maximum allowable distance between the box and support #1 for MC cable used for a 26 feet connection?

• A. 6 inches
• B. 12 inches
• C. 18 inches
• D. 24 inches

Answer: (B)

The correct answer is 12 inches because the National Electrical Code (NEC) specifies that for metal-clad (MC) cable, the cable must be secured at intervals not exceeding 12 inches from a box, cabinet, or any other structure. This regulation ensures that the cable is properly supported, preventing stress on the connections and maintaining electrical safety. In this scenario, with a 26-foot connection, the maximum distance allowed between the box and support #1 aligns with the NEC requirements, thereby supporting the integrity and safety of the installation. Understanding this requirement is essential for compliance and ensuring the proper handling of MC cable installations in various applications.
