About this detail

This electrical schematic details the power feed and control connections for wet scrubber main booster pump VFD-72441. A feeder from motor control center MCC73T1-17 utilizes three 350 KCMIL conductors and one number 4 ground in a two-and-a-half-inch conduit to supply the variable frequency drive. Output lines route power and control signals from the VFD through a junction box to local field devices including a motor space heater, temperature switch, local control station, solenoid valve, and pressure switch. A separate two-inch CAT6 communication line is also routed to the unit.
