What is the proper support spacing for flexible conduit?

• A. 6 inches, not to exceed 2 feet
• B. 12 inches, not to exceed 4.5 feet
• C. 24 inches, not to exceed 5 feet
• D. 36 inches, not to exceed 6 feet

Answer: (B)

The proper support spacing for flexible conduit is actually 12 inches, with a maximum spacing of 4.5 feet between supports. This standard ensures that the conduit is adequately secured to prevent damage and maintain electrical integrity. Flexible conduit is often used in applications where movement or vibration might occur, so appropriate support intervals help prevent sagging and potential strain on the electrical connections within the conduit. In practice, this means that conduits should be secured at regular intervals, allowing for enough flexibility while ensuring that there is no undue stress on the conduit itself. This spacing guideline helps comply with electrical codes and contributes to a safer installation.
