National Electrical Installation Standards

Standards as High as Your Own

Thursday, January 16, 2020


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,

Mike Long



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.
