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.)
To open the external doors, rotate the
latches 90° counter-clockwise until the
screwdriver slots are vertical.

Chapter 2 – Receiving, Handling & Storage
Receiving
Before leaving the factory, the motor control center is
given a final mechanical and electrical inspection and
is packed in accordance with the best practices for
electrical equipment.
On receipt of any apparatus, make an immediate
inspection for any damage or loss of equipment in
transit. Should damage or missing material be noted,
file a claim immediately with the carrier and notify the
nearest office of the General Electric Company.
Information such as a description of the damage, the
shipping crate numbers, the requisition numbers and
the panel catalog number should accompany the claim.
Handling
Control center sections are always shipped in an upright
position, in single or group sections. Sections must be
maintained in an upright position during all handling.
Never attempt to jack, lift, or move the equipment at
points other than the lifting angle or floor sills. Use two
or more chains or cables to distribute the weight evenly.
Pinch bars, pipe rollers or slings are useful implements
for handling equipment; but be careful to maintain
distributed loading and to always apply leverage at the
floor sills and/or lifting angle. Figures 4 and 5 illustrate
typical handling techniques.
Figure 5. Positioning the MCC with rollers
Storage
If it is necessary to store the equipment for any length
of time, be sure to observe the following precautions:
• Uncrate the equipment.
• Store the equipment in a clean, dry, humidity-controlled
area at moderate temperature. Cover with a suitable
canvas or heavy-duty plastic cover to prevent
entrance of foreign material.
• If equipment must be stored in cool or high humidity
areas, in addition to completely covering the equipment,
provide a heat source to prevent condensation of
moisture in the equipment . Energize space heaters (if
furnished in the equipment) or place a standard 120volt lamp rated at 75 watts inside the bottom of each
vertical section.

Chapter 3 – Installation
Before any installation work is begun, consult all
drawings furnished by the General Electric Company
as well as all applicable contract drawings for the
particular installation. Pay particular attention to the
location of units in the motor control center and their
relations to existing or planned conduits and busways.
Installation of Bottom Entry Conduits
Conduits can be stubbed in after the location of the
motor control center lineup has been established. Conduit
should be stubbed approximately 2 inches (51mm)
above the finished floor line. Figure 6 and Figure 7 show
the conduit entrance space available at the bottom of
standard sections. Exceptions to this available space rule
are indicated on drawings furnished by GE for specific
installations. Center the conduit beneath the section
vertical wireway to facilitate direct cable entry. Note:
Bottom rear entrance should only be used with full
rear accessibility.

Evolution Series E9000 Installation & Maintenance Guide
The overall height of the equipment should be considered
with respect to headroom, top conduit entry space and
alignment with other equipment.
Surface under motor control center base must
be of non-combustible material unless bottom
covers are installed in each vertical section.

available space for conduit entry) in 13-inch deep section, 6-inch cover.
Figure 7D. Upper position of ground and neutral bus (maximum
space available for conduit entry), 6-inch bottom cover.
Preparation of Flooring
For most installations, the MCC floor sills can rest on the
finished floor. The foundation for the equipment should
be level and even. Although not normally required, the
purchaser may elect to install, level and grout the steel
members or MCC floor sills in the floor, as illustrated in
Figure 8 and Figure 9. If the floor sills are removed, lifting
and moving the shipping sections must be done carefully.
If anchor bolts are to be imbedded in the foundation,
they must be located according to the drawings furnished
by GE for the specific equipment. For 13-inch (330.2
mm) deep vertical sections, anchor bolts or some form
of external bracing is required. Anchor bolts should be
1/2-inch diameter of Grade 2 steel (minimum).
If there are vertical sections of varying depths
(such as 13, 20, or 22 inches) in a single lineup,
the fronts of the sections must be lined up for
proper alignment of the main bus bars.
Figure 9 illustrates this point.

Positioning and Joining Sections
If groups of sections are to be joined together in a final
lineup, remove the end cover plates and the plug buttons,
from the sides of the sections to be joined. Figure 10
shows the side views, with the end cover plates
removed, for 20-inch-deep sections with 2-inch (50.8
mm) and 4-inch (101.6 mm) bus bars.
Carefully check and remove dirt, dust or bits of packing
material from the interior of all sections. Use a brush,
soft cloth or vacuum cleaner.
Evolution Series E9000 Installation & Maintenance Guide
Do not use compressed air to clean the equipment
if it contains moisture. Remove all hardware packages, drawings and other items shipped with the
equipment. Check all nuts, bolts, and electrical joints
for tightness.
All cables entering the bottoms of sections should be
pulled through conduits to a point where they will be
accessible after the equipment is in place. Sections can
be moved to their final position and properly leveled.

as illustrated. Note that for Condition 3, where there is
an enclosure on opposite sides of the working space,
the clearance for only one working space is required.
Figure 14. General Working Clearance Requirements
Installation of Top Entry Conduits
NEC Work Space
NEC Work Space is defined in Table 110.26(a) Working
Spaces. Included in these clearance requirements is the
step-back distance from the face of the equipment.
Table 110.26(a) provides requirements for clearances
away from the equipment, based on the circuit voltage
to ground, and whether there are grounded or ungrounded objects in the step-back space, or if there are exposed
live parts across from each other. The voltages to ground
consist of two groups: 0 to 150 and 151 to 600, inclusive.
Remember, where an ungrounded system is utilized, the
voltage to ground will be the greatest voltage between
the given conductor and any other conductor of the
circuit. For example, the voltage to ground for a 480volt ungrounded delta system is 480 volts.
See Figure 14 for general working clearance requirements.
Distances are measured from the live parts if the live
parts are exposed, or from the enclosure front if live
parts are enclosed. If any assemblies, such as switchboards or motor control centers, are accessible from the
back and expose live parts, the working clearance
dimensions would be required at the rear of the equipment,
After the motor control center is in place and leveled, and
the sections are joined together, conduits can be brought
into the tops of sections as required. Figure 15 and
Figure 16 show the conduit entry space available at the
tops of standard sections. Refer to drawings furnished by
GE for deviations on specific installations. Note: Top rear
entrance should only be used with full rear accessibility.
Always remove top cover plates when drilling
holes. This prevents small metal chips from falling
into the panel and cause serious damage.

Equipment Wiring
When pulling, bending, and terminating field wiring,
avoid scraping, cutting or otherwise damaging
cable insulation or strands.
Main Incoming Power Cables
Refer to the motor control center drawings provided by
GE for the location of the main disconnect or incoming
line terminals and the direction (top or bottom) of cable
entry. Cable-bending room provided within the vertical
section will meet or exceed National Electrical Code
requirements.
Incoming line sections are provided with cable supports.
Incoming cables must be firmly secured to withstand
the significant forces that may be generated during a
short circuit .
Cables secured at each support, as illustrated in Figure
17 and Figure 18 (600A example), will adequately
brace cables for faults of 100K RMS symmetrical
amperes, based on horizontal bus bracing. However,
cables should always be secured at the first support
inside the enclosure and at the support nearest to the
incoming terminals. Insulated bushings are also recommended at conduit terminations.
Figure 18. Typical bottom entry or main cables to the incomingline lug compartment (600A shown)
Align the conduit linearly directly over or as close as
possible to the supports. Run the cable in a convenient
orientation, making sure the cable is located against
the supports before it connects to the cable terminals.
Lash the cable using the following procedure:
Wrap the line cables together and, if provided, tie cables
together with nominal 3/8-inch (9.5 mm) nylon rope or
rope having a minimum tensile strength of 2000 pounds
(8896 N), at 6 inches (152 mm) and 12 inches (305 mm)
from the line terminals. Use five wraps and complete
every additional 6 inches with five wraps or every 1 inch
(25 mm) with one wrap. Use supplied cable supports as
desired. Refer to UL 891.
Individual Unit Wiring
Open the vertical wireway door(s) and the top and/or
bottom horizontal wireway hinged covers. All doors
can be removed, if desired, by extracting hinge pins or
removing the hinge.
10
Evolution Series E9000 Installation & Maintenance Guide
When installing cables, be sure to not damage
the cable insulation on any sharp edges, such as
steel work or screws.
Where access to the rear of the section is available,
cables can be brought into the space behind the vertical
bus and brought forward into the front wire trough
area through any of the modular openings in the righthand steel support plate.
Wiring NEMA Type A Motor Control Centers
Use the following procedure to wire NEMA Type A
MCCs:
1. Remove black plastic barrier closest to unit connection
points and remove knockouts as required.
2. Pull load cables near the unit to be wired. Measure
(allowing for cable bends), cut and strip the cables,
and feed them carefully through barrier knockout
into the unit. Terminate the cables on the feeder or
starter lugs provided in the unit. If aluminum wire is
used, coat the wire strands with an oxide-inhibiting
grease specifically designated for use with aluminum
cable. Install plastic side barrier.
3. Pull the control wiring, then measure, cut, strip, and
terminate it on individual device terminals in the unit.
4. When specified, an optional ground lug is provided
in each draw-out combination starter unit for terminating a motor-frame grounding wire. (For larger
starters, the lug is mounted on the horizontal
ground bus.)
5. Use cord or plastic ties to secure all wiring. Route the
wiring to avoid interference with moving parts and
to keep it away from heat-producing components,
such as resistors and fuses.
6. Verify that the connections on all devices and terminal
blocks are tightened to their proper torque values,
as listed on the label on the vertical wireway door.
Wiring NEMA Type B Motor Control Centers
Use the following procedure to wire NEMA Type B MCCs:
1. Remove black plastic barrier closest to unit connection
points and remove knockouts as required.
2. Pull load cables near the unit to be wired. Measure
(allowing for cable bends), cut and strip the cables,
and feed them carefully through barrier knockout
into the unit. Terminate feeder cables directly on the
lugs on the disconnect. Connect the motor leads at
the starter terminals if either of these conditions is met:
a. The motor control center is furnished as
“NEMA B-D wiring” (where D=Device) or
b. The starter is NEMA size 6 or smaller.
Connect the motor leads to the starter at the T1, T2,
and T3 terminals if these conditions are met:
a. The equipment is furnished as “NEMA B-T” wiring
and
b. The starter is NEMA size 2 or smaller.
Install plastic side barrier after power and control
wiring in Step 4 is complete.
Aluminum wire is not recommended for this product.
3. Pull the control wiring, then measure, cut, strip and
terminate it at the terminal blocks provided within
the unit. Optionally, control terminal blocks may be
pulled apart and the plastic knock-outs removed to
allow wiring outside the bucket. The terminal blocks
can then be placed back through the plastic knockout openings and reinstalled. This method allows
wiring to terminal blocks outside the confines of the
starter unit.
4. When specified, an optional ground lug is provided in
each draw-out combination starter unit for terminating
a motor frame grounding wire. (For larger starters,
the lug is mounted on the horizontal ground bus.)
5. Use cord or plastic ties to secure all wiring. Route the
wiring to avoid interference with moving parts and
to keep it away from heat-producing components,
such as resistors and fuses.
6. Verify that the connections on all devices and terminal
blocks are tightened to their proper torque values,
as listed on the label on the vertical wireway door.
Wiring NEMA Type C Motor Control Centers
Master terminal boards in NEMA Type C motor control
centers are provided in the larger top or bottom horizontal wireway of each vertical section. (Refer to the
drawings provided by GE for the locations of master
terminal boards.) Figure 19 and Figure 20 show typical
Type C terminal board arrangements.
These terminal boards are connected at the factory to
control terminal blocks of plug-in units in each vertical
section. Wiring diagrams provided by GE show these
terminal points. These terminal blocks are also factory
wired to the T1, T2 and T3 motor-lead terminals for each
NEMA size 1–2 starter unit in each vertical section.
11
Evolution Series E9000 Installation & Maintenance Guide
Field connections to these control and load terminals
should be made at the master terminal boards.
Make field connections to all feeders and motor loads
for starters larger than NEMA size 2 as described for
NEMA Type B motor control centers.
Optional grounding lug can be provided in each Plug-in
unite if vertical ground bus is specified.
Figure 21. Side cutout dimensions on 13", 20", 22" and 25".
If rear access is used, a rear main bus barrier
is a required option.

Figure 20. Typical Type C terminal boards in multiple sections
Wiring Between Sections
Figure 21 shows the dimensions of side cutouts in each
vertical section for wiring between sections. Cross-wiring
can be accomplished at both the top and bottom of
sections. 20”or 22”deep vertical sections accessible
from the rear can be cross-wired in the open rear area,
with the wiring brought forward through oval openings
in the rear of the vertical wireway.
Terminal Blocks
The new style terminal blocks are mounted on a metal
rail located at the bottom of the unit, as shown in
Figure 22. The terminal block easily slides into position
from either side of the mounting rail.

9. Slide the unit into the vertical section, then push at
the top and bottom until the stabs are fully engaged
with the vertical bus.
10. Rotate the latches at the top and bottom of the unit
clockwise to engage the latches with the horizontal
shelves above and below the unit. See Figures 25
and 26.
11. Verify the operation of the disconnect handle and
safety interlocks, as described later in this manual.
Use the following procedure to install a motor control
center unit:
1. Attach the door hinges to the left side of the section,
line up the door with the hinges, then insert the hinge
pins to secure the door. Install a hold-down bracket
with the lower door hinge, but do not tighten the
mounting screw at this time.
2. Place the two tabs on the left side of the shelf into
the appropriate openings in the section structure.
3. Lower the right side of the shelf and snap the two
detents in the right-side flange into the two holes in
the side of the vertical wiring trough barrier, as
shown in Figure 24. Swivel the shelf hold-down
bracket and grounding spring into place and tighten
the lower case hinge.
4. Examine the new unit carefully, front and rear, to
ensure that all screw terminals are tight, all foreign
material and packing are removed, and the insulating barriers are secure.
5. The unit disconnect must be in the OFF position
before the unit can be inserted into the vertical
section.
6. If necessary, rotate the latches at the top and
bottom of the unit so that they are horizontal.
7. Remove the snap-in cover over the vertical bus
stab-in openings at the appropriate installation
location for the unit to be installed.
8. Lift the unit and place its base on the front horizontal
surface of the snap-in shelf.

5. Turn the latches at the top and bottom of the unit a
quarter turn counterclockwise to release the unit.
These latches are shown in Figure 25 and Figure 26.
6. Pull unit out to remove it, being extremely careful to
support its weight as it is fully withdrawn.
7. The door over the withdrawn unit can be latched closed.
8. If desired, a blank door can be ordered to cover the
unused opening. (For large unit spaces, two blank
doors and a horizontal unit shelf may be required.)
Latch
Figure 26. Quarter-turn latch located at the bottom of the unit.
Removal of Draw-Out Motor Control Center Units
Some units may still have control power applied
from an external source after the unit disconnect
has been switched to the OFF position. Be extremely
careful when removing units from any motor
control center. Failure to observe this precaution
can result in serious injury or death.
The procedure for removing a motor control center
unit is generally the reverse of the procedure for
installing a unit:
1. Ensure that the unit disconnect is in the OFF position,
as shown in Figure 25.
2. Turn the door latches a quarter turn, open the unit
door and the vertical wiring trough door.
3. Disconnect all field-connected wiring by separating
the pull-apart terminal blocks in the unit. Pass the
terminal blocks and wires into the vertical wiring
trough. Note that the plastic knock-outs in the vertical wireway barrier can be removed and left within
the vertical wireway, with the field wiring, rather
than threading the wiring and terminals back
through the knock-out.
4. Disconnect any other field-installed wires that are
terminated in the unit. Remove these wires from the
unit, tag them (if desired), and leave them in the
vertical wireway adjacent to the unit.
Operating Handles, Door Interlocks and
Padlocking Provisions
All Evolution motor control center units are furnished
with disconnect operating handles that are integral to
the unit structure. The position of the disconnect
(ON–OFF for switches or ON–OFF–TRIP for circuit breakers)
is indicated by the position of the operating handle.
The operating handle is interlocked with a catch on the
inside of the unit door to prevent inadvertent opening
of the door when the disconnect is in the ON position,
as shown in Figure 27. Switching the handle to OFF
allows access to the interior of the unit.
Each disconnect operating handle is equipped with an
interlock that prevents opening the door when the disconnect is ON.
A concealed screw can be turned counterclockwise
with a 5/32” Allen wrench to defeat the door interlock
and access the breaker disconnect when ON, as shown
in Figure 28. Only qualified personnel should be
allowed to defeat the interlock.
Be careful with any field wiring removed from a
unit that may become energized. Such wiring
must be adequately insulated to avoid inadvertent
contact. Failure to observe this precaution can
result in serious injury or death.

The disconnect is also equipped with a padlocking provision, so that the operating handle can be locked in the
OFF position with as many as three padlocks, as shown
in Figure 30. The handle can also be drilled to accommodate one padlock to secure it in the ON position. In
either case, the unit cannot be withdrawn because of
interference between the padlock(s) and door.
CAUTION should be used when removing or
installing units consider the weight in table above.
Two persons may be required or the assistance of
a lifting devices. See page 21 for suggested lifts.

Chapter 4 – Operation
Preparing for Initial Operation
In addition to the normal circuit checking after wiring is
completed, the following specific actions should be
taken before energizing the equipment:
1. Check and tighten any electrical connections, such
as lugs and bus splices that may have loosened
during shipment, handling and installation. Torque
values are provided on or adjacent to components or
lugs. See torque labels in MCC vertical wireway door.
2. Operate each magnetic device by hand to verify
that all moving parts operate freely. Check all electrical contacts for proper operation.
3. Current transformers are shipped with a shunt
across the secondary if the circuit is not complete.
Remove the shunt after completing the connections
to the transformer secondary.
4. Verify that the horsepower and voltage rating of
the motor agree with the rating stamped on the
starter unit to which it is connected.
5. Check each overload heater or electronic overload
relay setting against the motor full-load current.
Check current transformer-operated overload
relays to be certain that overload heaters are
in place. Do not operate starters without
overload protection.
6. Check all circuit breaker trip settings and fuse ratings
against the drawings supplied with the equipment.
a. If trip settings must be changed, use the GE rating
plug extractor tool (catalog number TRTOOL) to
remove rating plugs from Spectra circuit breakers.
b. See the startup procedure following information
regarding instantaneous trip settings on magneticonly circuit breakers.
The operating handle should move upward to the
OFF position after the breaker has been reset. After
the reset, turn the circuit breaker ON and then OFF
to confirm proper operation.
10. Visually check all units and enclosures to ensure
that electrical spacings have not been reduced
because of shipping and handling actions.
11. Verify that the motor control center enclosure and
units are grounded.
12. Replace all protection barriers and panels that have
been removed during installation.
13. Carefully clean the equipment interior with a clean
cloth, soft brush or vacuum cleaner to remove all
metal chips, dust, wire and other debris.
14. After taking precautions to prevent accidental contact
with the motor control center buswork, conduct the
following insulation-resistance test with a 1000 Vdc
(Megger) tester. With all disconnects in the OFF position,
• Apply voltage between all phase pairs.
• Apply voltage between each phase and ground.
All readings should be 1 megohm minimum; typical
values will be 50–100 megohm but may vary
based on humidity.
Similarly, test individual feeder and motor circuit
wiring (field wiring) as each set of conductors is
pulled into the motor control center, before terminating the conductors at either end.
15. With all disconnects OFF, close and latch all doors
and secure all external covers.
Initial Operation of the Motor Control Center
Because of problems that may occur during
the initial energizing of the motor control
equipment, only qualified personnel should
carry out this startup procedure.
Do not exceed the long-time and/or instantaneous trip settings stipulated in the National
Electrical Code and as identified in the overload
heater selection tables in this manual.
7. Check all pneumatic or motor-driven timers for
proper time-interval settings.
8. Manually operate all branch-circuit disconnects
and verify proper operation of disconnects and
door interlocks.
9. Where applicable, manually trip all circuit breakers
to verify that operating handles move freely to the
TRIP indicating position. With the door closed and
latched, reset each tripped circuit breaker by pushing
the operating handle down beyond the OFF position.
Use the following procedure for initial startup of the
motor control equipment. Be sure that the steps in the
previous section, Preparing for Initial Operation, have
been completed.
1. Ensure that all doors are closed and latched and all
external covers on the motor control center are
secured.
2. Verify that all main and branch disconnects within
the motor control center are OFF.
3. Verify (with an insulation-resistance tester) that all
main incoming feeders to the motor control center
are adequately insulated.
4. Close the upstream feeder to energize the motor
control center.
18
Evolution Series E9000 Installation & Maintenance Guide
5. Close the main disconnects, if any, at the motor
control center.
6. Close each branch-circuit disconnect or feeder at
the motor control center.
7. Operate each motor starter individually to verify satisfactory operation, including the following parameters:
• Motor rotation
• Pilot light indication
• Electrical interlocking
• Acceleration and sequence timing
Power-factor correction capacitors on
individual motor circuits should be temporarily
disconnected during startup.
8. Adjust instantaneous settings on magnetic-only circuit
breakers and/or fuse sizes and overload heater
selections to achieve proper motor and branch circuit
protection. (See NEC Article 430.52.) Since the
adjustable trip setting on magnetic-only circuit
breakers is factory set at the minimum trip position,
nuisance tripping may occur on initial motor starting.
Increase the trip setting in increments until tripping
no longer occurs during motor starting. Do not exceed
the maximum trip settings given in overload relay
tables in this publication. All adjustable overloads
are also factory set at minimum. Check motor
name-plate data and set overloads accordingly.

Chapter 5 – Maintenance
Equipment Maintenance
De-energize all equipment before performing any
maintenance operation. There may be voltage
present within the equipment from remote
sources, even though all main- and branch-circuit
disconnects have been opened at the equipment.
Failure to observe this precaution can result in
serious injury or death.
The customer should prepare a maintenance program
consisting of a schedule and checklist matrix listing items
to be periodically examined on the installed equipment.
The frequency and extent of the maintenance activities
will vary depending on such factors as equipment usage
and environmental conditions. In any maintenance
program the following actions should be included:
1. Remove accumulated dust and dirt with a soft
cloth, brush or vacuum cleaner.
2. Wipe clean all main bus insulators and vertical bus
barriers.
3. Inspect main and vertical bus joints and main bus
supports and tighten, if necessary. Refer to Table 1
for torque specifications.
4. Inspect all wiring from units for deterioration of
insulation.
5. Remove draw-out units and check stabs and all
unit wiring. Remove accumulated dust from
horizontal shelves and the areas around stabs.
6. Check all starter contacts. They need only be
replaced when nearly all the silver tip is gone and
the contact tip support is exposed. Do not file the
contacts. Filing or otherwise dressing the contacts
only results in lost tip material and reduces starter
life. See GE publication GET-6915A for questionable
contact appearance.
7. Check all unit wiring for deterioration of insulation
and tighten all connections.
8. Visually check meters and instruments. Check critical
instrument calibrations.
9. Check all unit door interlocks for proper operation.
10. Check all indicating lights and replace, as required.
11. If fuse replacement is necessary, always install the
same type and rating as the fuses furnished with the
motor control center. Fuse designs may be mechanically equivalent but not electrically equivalent.
They may not have the same short-circuit withstand
and current-limiting ability.
Control Power Fusing
Control fuses are front accessible except in the 6-inch
compact starter. Remove 6-inch FVNR starter for
maintenance. Fuses are located on the side, as shown
in Figure 40.
