Question:
Can electrical metallic tubing (EMT) be installed to supply a fire pump. The installation would be from the load side of the fire pump controller overhead on a ceiling of the fire pump room and then a vertical drop of the ceiling to the motor. There would be a transition from EMT to liquid-tight flexible metal conduit within 2 feet of the motor terminal housing. Job specifications are calling for rigid metal conduit.
Thanks for any Code view on this,

Answer:
Hi Mike,
The short answer is yes. Section 695.6(D) includes EMT as a wiring method recognized for use between the fire pump controller and the motor(s). That said, remember the Code is the minimum, meaning one must do at least that much. A job specification or engineering design may be more restrictive than the NEC requirements. Probably best to check with the local electrical inspector (AHJ), engineer or designer, and possibly the owner.
