General Description –
Vertical Section Enclosures
Each Evolution MCC vertical section is assembled with
two full-side sheets having openings near the top and
bottom for lateral busing and wiring between sections.
Multiple sections are joined together at the factory in
three-section (maximum) shipping splits. Each shipping
split is provided with continuous floor sills and a lifting
angle. Floor sills and lifting angles are field removable.
Each shipping split includes a continuous non-removable
main horizontal bus. Main bus splice bars are provided
within each shipping split for field connecting main
busses. Refer to motor control center outline drawings
furnished by the General Electric Company for location of
shipping splits within each motor control center lineup.
Vertical sections are normally provided with a top (12"
high) horizontal wireway and a bottom (6" high) horizontal
wireway. Each vertical section is also provided with a
vertical (4" wide) wireway. Hinged doors are provided
over horizontal and vertical wireways. (These doors can
be removed by extracting the hinge pins inside the doors.)
Secure Open
Because of the great variety of motor controller
assemblies and components provided within industrial
motor control centers and to satisfy floor-space limitations
at installation sites, a large variety of vertical section
dimensions are provided, as follows:
• Section Height: 90”, 78”, 66” etc.
• Section Width: 20”, 24”, 30” etc.
• Section Depth: 13”, 20”, 22” or deeper
for large assemblies.
Refer to motor control center drawings
furnished by GE before performing any
field-installation work.
To open the external doors, rotate the
latches 90° counter-clockwise until the
screwdriver slots are vertical.
Disconnect equipment from all electrical
services before performing any installation
or maintenance work.
