Recloser installation procedure
WARNING
This equipment is not intended to protect human
life . Follow all locally approved procedures and safety
practices when installing or operating this equipment .
Failure to comply can result in death, severe personal
injury, and equipment damage .
G102 .1
WARNING
Hazardous voltage . Always use a hotstick when working
with this equipment . Failure to do so could result in
contact with high voltage, which will cause death or
severe personal injury .
G108 .1
All reclosers are carefully tested and adjusted at the factory
to operate according to published data. Well-equipped test
facilities, detailed testing procedures, and thoroughly trained
personnel assure accurately calibrated equipment. Each
recloser leaves the factory ready for installation—pending
completion of the steps in this procedure.
Eaton recommends transporting SPEAR single-phase
reclosers in the closed position to maximize the operational
performance of the unit.
1. Check the data plate ratings. Make sure the ratings on
each recloser data plate (see Figure 11) are correct for
the planned installation.

2. Perform high-potential withstand tests. Prior to
installing the SPEAR single-phase recloser, perform
a high-potential withstand test. Refer to the
section of this manual for
high-potential withstand test procedures. This test
will help identify any shipping damage affecting the
dielectric condition of the recloser or the vacuum
integrity of the interrupter.
CAUTION
Personal injury . Sheds on epoxy encapsulation have
sharp edges . Wear protective gloves when handling
the unit . Failure to do so can result in cuts and
abrasions .
T258 .1
WARNING
Falling equipment . Use the lifting lugs provided and
follow all locally approved safety practices when lifting
and mounting the equipment . Lift the unit smoothly
and do not allow the unit to shift . Improper lifting
can result in severe personal injury, death, and/or
equipment damage .
G106 .3
3. Mount the recloser. Use the lifting lugs located on the
head casting and follow approved procedures. At this
point, the contacts are open, the bypass switches are
closed, and the disconnect switches are open.
IMPORTANT
The default connections use the horizontal bushing as the
source side and the vertical bushing as the load side. Also,
the horizontal bushing may be used as the load side and
the vertical bushing as the source side. Note that reversing
the source and load bushings has no effect on overcurrent
protection but may require setting or wiring changes to the
control for correct metering.
To allow various mounting arrangements, such as
substation or pole-mounting applications, the module
may be rotated in two of the four positions illustrated.
See Figure 12. Position A or Position B are acceptable
module rotations, with Position B as factory shipment
default. Positions C and D do not allow adequate
clearance and are not acceptable module rotations.
IMPORTANT
If the module is rotated, it must be properly reattached to
the tank. Center the module over the tank lip and tighten
the four bolts that secure the module to 25–40 ft•lbs
(34–54 Nm).
WARNING
Hazardous voltage . Recloser and control must be
solidly grounded . Follow all locally approved procedures
and safety practices when grounding this equipment .
Improper grounding can result in contact with high
voltage, which will cause death or severe personal
injury .
