General
Installation Location
Read the entire manual before attempting to perform
installation of this transformer. Dry type transformers are
suitable for indoor or outdoor use depending upon the
construction of the enclosure as well as the ability to
protect the transformer from unwarranted access to live
parts. They are cooled by the free circulation of air
through the enclosures, the average ambient
temperature over 24 hours should not exceed 30° C
(86°F), the maximum ambient temperature should not
exceed 40° C (104°F) or as otherwise specified in the
specification. Overheating may occur if the air flow is
restricted, the transformer is overloaded, it is supplied with
over or under voltage, or operated at other than rated
frequency.
Inspection upon Receipt
Units are shipped in upright position and should arrive that
way. Upon arrival, all units should be inspected for
damage during shipment. Unpack and examine for
broken or loose parts. Careful inspection should be
made of transformer coils, wiring and insulators. What
appears to be minor damage in these areas may result in
an open or short circuit. Claims for damage should be
filed with the transportation company and an ACME
Electric representative must be notified immediately. For
superficial or minor case part damage, spare parts
may be available, contact an ACME Electric
representative.
Handling
Lifting with hand trucks or fork lift trucks is permissible if the
blades or forks are long enough to pass completely under
the case. Since most general purpose transformers have
a high center of gravity, extreme caution should be
exercised when lifting or moving the units.
Factors to be kept in mind when choosing a location for
dry type transformers are: accessibility, ventilation,
environmental conditions, and noise (see ‘Reducing
Sound Levels’). Installation should be made in an area
reasonably free from dust, excessive moisture,
fertilizers, chemicals and other corrosive fumes or
vapors and separated from flammable materials in
accordance with the NEC.
General purpose dry type transformers up to case GPC+ are
supplied in dual rated enclosures suitable for indoor/outdoor
installation and eliminates the need of a weather shield kit.
Weather shield kits are for cases GPD and GPE which are
available to convert these enclosures for UL listed outdoor
NEMA 3R use. The appropriate kit can be obtained from a
ACME Electric
properly attached weathershield kit, no transformer
should be hosed off, or placed in the catchment area of a
water sprinkler. Wall-mount brackets are also available
for units up to 75 KVA.
In all locations dry type transformers must be installed in
the upright position in an area with free air
circulation. Check NEC codes for minimum required
clearances from adjacent structures. Fencing in the
transformer to prevent unauthorized access is strongly
recommended.
Transformer
representative. Even with a
Room Requirements
Dry-type transformers located indoors should comply
with the application requirements of NEC.
The room in which dry-type transformers are located
should be sized to permit locating transformers with
sufficient spacing between units and sufficient
clearances to walls and other obstructions (as
specified per NEC or as indicated below nameplate) to
permit air circulation. Sufficient space should also be
provided to permit routine inspection and maintenance.
If it is necessary to move ventilated dry-type transformers
during inclement weather then they should be thoroughly
protected against the entrance of moisture.
Storage
Storage areas should be as clean and dry as possible
without extreme temperature variations. Protective
wrappings should be left intact until the transformer is
moved to its permanent location. Dry type transformers
stored under extremely wet or dusty conditions must
have cleaning and drying operations performed before the
unit can be energized. (See Maintenance Section.)
Adequate ventilation is essential for the proper cooling of
transformers. Clean, dry air is desirable. Filtered air at or
above atmospheric pressure may reduce maintenance
if dust or other contaminants present a particular
problem. When transformers are located in rooms or
other restricted spaces, sufficient ventilation should be
provided to hold the air temperature within established
limits when measured near the transformer inlets. This
will usually require approximately 100 ft3/min of air per
kilowatt of transformer loss. The area of ventilating
opening required depends upon the height of the room,
the location of openings, and the maximum loads to
be carried by the transformer. Room ventilation should
not impede normal circulation of air through the
transformer.
When possible, the air inlet to the room should be near the
floor with the outlet in the opposite upper end of the room.
The exhausting air should not exceed 15°C over the inlet
air temperature. When necessary, forced air exhaust should
be used to maintain this maximum differential.

Grounding
Cautions: Make only those connections shown on the
nameplate or connection diagram. Before energizing,
check all tap jumpers for proper locations, and all bolted
connections for tightness. All three sets of taps on a
three phase transformer must be connected in the same
location for each phase. For instructions on how to read
nameplates and connection diagrams, please visit the
documentation section of our website at:
http://www.hubbell.com/acmeelectric/en .
All transformers, with bottom connections are designed for
easy accommodation of cable sizes in accordance with
NEC. Cables which will carry less than 100 amperes may
have a 60° C temperature rating or higher, and
cables which will carry 100 amperes or more must have a
75° C temperature rating or higher. All cables should be
in the lower part of the transformer enclosure in
accordance with markings on the enclosure.
Use 90° C cable sized to 75° C ampacity for the
units having terminals located above the coils. After
the first thirty days of service, re-tighten all connecting
lugs and bolts. Depending on the kVA rating, the
transformer may have flexible leads with bolted type
wire terminals, copper/aluminum (CU/AL) lug connectors,
or simply termination pads for mounting your own
crimp or lug type terminations. The table below shows
required torque for installing bolted wire connectors and
cables in lug type connectors.
It is the responsibility of the installer to ground the
transformer enclosure assembly to the ground system in
accordance with the latest revision of the NEC Section
450-10, NEC Article 250 and ANSI/IEEE Std. 144.
Reverse Feed or Step-up Operation
Step-down transformers may be reverse fed for step-up
operation to increase voltage. This means that the incoming
power is connected to the low voltage (X’s) and the load is
connected to the high voltage (H’s). If the low voltage is wye,
the X0 terminal must NOT be connected in any way.
Likewise, if the low voltage is a delta with a 120 volt lighting
tap (high-leg), the X4 terminal must NOT be connected in
any way.
CAUTION: Much higher than normal inrush currents may
occur with reverse feed operation and may cause nuisance
fuse blowing or breaker tripping. For this reason, fuses and
breakers with time-delay characteristics must be used.
If a breaker is used for incoming over-current protection, it
must be a thermal-magnetic type breaker, not a magneticonly type breaker.
Tap Settings are for the high voltage side and when reverse
fed the ability to adjust voltages is no longer available. This
means some performance parameters may be affected.

NOTES:
1. Always use two wrenches when tightening or loosening
bolted connections to prevent damage.
2. Tighten, wait several seconds, then re-tighten all
connecting lugs and bolts.
Minimum electrical clearances in the installation of lugs
and cables must be per ANSI and NEMA Standards. All
electrical clearances that are questionable must be
insulated for the applied voltage. Particular care should
be taken with shielded cables, so that the ground termination of the cables has sufficient clearance from all the
manufacturers installed live parts, including parts that
appear to be insulated.

Reducing Sound Levels
Transformer noise originates within the steel core. It is
n inherent characteristic of all transformers and cannot
a
be completely eliminated. Therefore, care should be
exercised in the selection of the transformer location,
particularly in buildings where the ambient sound level is
quite low. A transformer's sound level is quite often
unintentionally amplified by improper installation, which
makes the transformer appear to be considerably louder
than it actually is. Transformer sound levels are
amplified by sound waves in the air being reflected from
surrounding objects and resonance of mounting
construction and electrical connections. This situation
should be avoided wherever possible. Transfor m e r s
sho u l d b e connec t e d for and energized at rated
vol t a g e an d fr equency at no load to de t e r m i ne the
cor r e c t n oise level. Transformer sound level
problems can also be further minimized by following
these installation suggestions:
1. The case may be installed on vibration mounts for
additional reduction of sound levels.
2. Flexible conduit couplings should be used to reduce
vibration transfer from the case to the incoming and
outgoing conduit.
3. The installation should be in an area where the
sound will be least objectionable.
4. Avoid stairway and hall areas or reflecting objects
which resonate or echo. Concrete or masonry walls,
floors and ceilings are excellent sounding boards. If
these and other reflecting surfaces cannot be
avoided, acoustic absorbing materials should be
used to cover them.

Page 6
5. Mounting the transformer on walls, balconies or
floors which have relatively light mass should also
be avoided. The possibility of amplifying the sound
waves in the structure will be greatly reduced if the
weight of the mounting surface corresponding to the
projected area of the transformer is equal to, or
greater than the weight of the transformer. Surfaces
which may distort or strain the transformer case
should be leveled or squared before installation.
6. Shrubbery can be planted near the unit on outdoor
installations to break up the sound pattern. Make
sure all sprinklers are aimed away from the
transformer.
7. Incoming line over-voltage is higher than tap setting.
Change the tap settings according to the incoming line
voltage.
compressed air or nitrogen should be clean and dry and
should be applied at not more than 25 psi.
Lead supports, taps, terminal boards, bushings and
other major insulation surfaces should be brushed or
wiped with a dry cloth. The use of liquid cleaners is
undesirable because some of them have a
deteriorating effect on most insulating materials.
As long as the transformer is energized, humidity
conditions are unimportant. In the event that a dry
type transformer is de-energized and allowed to
cool to ambient, consideration must be given to the
possible effects of humidity. If moisture is noted, it
should be removed by drying with heated air from a
blower, with the maximum temperature of 110°C or
230°F. The heat must be distributed in the
enclosure. Incandescent lamps or heaters may also
be used if the same temperature limitations are
observed.
8. Transformer installed too close to other noise generating
transformers. Check adjacent transformers and isolate
with acoustical barriers.
9. Loose parts of transformer enclosure, such as panels or
loose bolts. Check panels and parts and tighten loose
bolts and nuts.
10. Loose parts on core & coils that may have dislodged or
shifted during shipment or installation. May require
torquing bolts, nuts and coil support blocks.
11. Imbalanced loads. All three phase loads should be
balanced per ANSI tolerances.
12. Triplen harmonic generating loads. Third harmonic
circulating in delta primary will add over excitation.
Disconnect load from transformer and then check sound
level.
Prior To Energizing
After the installation is completed, remove any debris from
the bottom of the cable compartment and from under the
transformer. After the transformer has been installed, but
before it is energized, all shipping braces should be
removed. Tighten securely all external bolts to eliminate
any vibrations. Check tap jumpers for proper location, and
all bolted connections for tightness. (use two wrenches).
Maintenance
Although dry type transformers require less maintenance
than liquid filled transformers and other electrical
devices, periodic cleaning and inspection on the average
of at least once a year should be performed except
under extraordinary conditions, in which case the
inspections should be made more often.
Lighting Tap Applications
Most transformers with 240V delta secondaries have a
120V single-phase lighting tap. The maximum single-phase
120V load can not exceed 10% of the three-phase
kVA rating. The load must also be balanced at 5%
maximum between X1 and X4 and 5% between X2
and X4. The three-phase kVA rating will be reduced
by 15% when lighting tap is used to maximum capacity.
Dielectric Insulation
Transformer insulation system is designed to protect the
integrity of the transformer to the BIL rating on the
nameplate. If exposed to lightning, switching surges or
severe transients, additional protection such as surge
arrestors, surge capacitors or a higher BIL rating should
be provided.
Ambient Temperature
Limiting ambient temperatures for normal service
conditions are specified in ANSI Standards for
Transformers. Transformers depend entirely on the
surrounding air for adequate ventilation. The ambient
should not exceed 40° C (104° F) and the average
temperature of the air for any 24 hour period should not
exceed 30°C (86° F). For operation at higher ambient
temperatures, transformer loading should be reduced
0.6% of rated kVA for each degree above 30° C average
ambient to a maximum of 50° C (unless transformer is
specifically designed for this temperature). The use of
transformers in cooling air above 50° C is not covered
by this guide, and the manufacturer should be
consulted before such installations are made.
The unit must be de-energized and properly grounded
before checking for loose connections or parts,
accumulations of dirt on insulating surfaces, and dust
which tends to restrict air flow. The windings may be
cleaned with a vacuum cleaner, a blower, or with
compressed air. The use of a vacuum cleaner is
preferred as the first step in cleaning followed by the
use of compressed air or nitrogen. The

Altitude
Transformers are normally designed for operation at
altitudes up to 1000 meters (3300 feet). To operate a
transformer above 1000 meters requires special
considerations in winding insulation. Consult your nearest
sales office for additional details. Refer to the latest edition
of NEMA ST20 for detailed guidelines.
Single Phase Three Wire Operation
Transformer is shipped from the factory with a link between
X2 & X3 for single phase three wire operation. X2 & X3 link
can be treated as neutral and can be solidly grounded. X1 to
neutral and X4 to neutral can be loaded up to 50% of kVA
each and will provide 120 Volts output. X1 & X4 will provide
240 Volts output.
If only 120 Volts is desired then remove the links (there will
be 2 links) between X2 and X3 and connect X1 to X3 and X2
to X4 to make windings in parallel.
References
All transformers are manufactured per NEMA and
ANSI/IEEE standards. Where the UL Label is affixed,
the transformer conforms to UL requirements.
