Trade size 3/8 inch flexible metal conduit (FMC) can be used for tap conductors for luminaires if the length does not exceed?

4 feet
5 feet
6 feet
7 feet

The correct answer is: 6 feet

The length limitation for using trade size 3/8 inch flexible metal conduit (FMC) for tap conductors with luminaires is set at 6 feet. This standard is established to ensure that the installation remains safe and compliant with electrical codes. The 6-foot maximum is designed to minimize the potential for heat buildup and stress on the conductors, which can occur in longer runs. It is important to recognize that FMC is often used for its flexibility and ease of installation, particularly in tight or tricky spaces, but there are specific limitations when it comes to its application to ensure electrical safety and functionality. Conductors within these conduits must be secured properly and the overall installation must follow guidelines to prevent damage or overheating. The choice of a 6-foot limit reflects the balance between practicality in installation and adherence to safety standards.
