During the inspection of a recently installed conduit system, an inspector identifies that a section of flexible metal conduit (FMC) exceeds the maximum length permitted by the CEC. The FMC is being used for a motor connection. What is the maximum length of FMC generally permitted by the CEC for such applications in dry locations?

Question: During the inspection of a recently installed conduit system, an inspector identifies that a section of flexible metal conduit (FMC) exceeds the maximum length permitted by the CEC. The FMC is being used for a motor connection. What is the maximum length of FMC generally permitted by the CEC for such applications in dry locations?

Answer options:

• 1.0 m (3.3 ft) ✅ 1.2 m (4 ft)
• 1.5 m (5 ft)
• 1.8 m (6 ft)

Correct answer: 1.2 m (4 ft)

Explanation: Rule 12-1006(6) of the CEC generally limits flexible metal conduit (FMC) to a maximum length of 1.2 m (4 ft) for connections to motors in dry locations. This rule ensures adequate protection and ease of replacement while limiting potential damage to conductors from excessive movement.
