use of EMT in fire pump feeders
Read 695.6
695.6 B 3-Be a listed electrical circuit protective system with a minimum 2-hour fire rating.
The insulation of RHH wire is rated for 2hrs fire rate.
I thing that If you run EMT expose you should use this wire.
But from the motor control to the pump motor you should use RMC with LFMC (695.6 E).
