level surface near the utility
pole
• Remove the four angled top
boards from the shipping
crate
• Remove any options included
• Remove the clamping board
from across the switch base
• Leave switch on its pallet until
ready to install
• Compare switch with the
photo to be sure all items
have been included
• Contact your factory
representative if any parts are

Wiring
CONDUCTORS
• Using your company’s
standard practices, train the
conductors to the switch
terminal pads
• Use sucient conductor
length to allow for ease
CONNECT HIGH VOLTAGE
CONDUCTORS
• Wire brush mating surface of
the switch terminal pads and
terminal connectors
• Wire brush connector
surfaces where conductors
will be secured
• Wire brush conductor
surfaces
• Apply a contact sealing paste
to the cleaned surfaces (A.B.
Chance Z.L.N. or equivalent)
• Assemble connectors,
conductors and hardware to
the switch terminal pads
• Ensure bolt heads of the
terminal connectors are
on the insulator side of the
terminal pad as shown.
• Torque all supplied hardware
to 60 ft-lb.
• Torque user supplied
hardware according to your
company standards.
High Voltage Electrical Arc Hazard
May cause property damage.
Install terminal connectors with bolt heads
toward the insulator. Failure to do so may
compromise the electrical insulation resulting
in an electrical arc.

Operation
GENERAL
Operation of the BP3 By-Pass
switch is shown in Figures 4 and
5. In normal operation, the by-
pass blade is open and the two
disconnect blades are closed
(Figure 4), allowing the recloser
to be in the circuit. When
isolation of the recloser is
required, close the by-pass blade
to provide a parallel current path.
Open the disconnect blades
(Figure 5) to isolate the recloser
from the circuit.
• Position yourself below and
slightly to the front of the
switch’s hook stick pull ring
• Position feet and body in a
manner that provides good
stability and allows for hook
stick use without losing a
steady footing
• Under ice conditions, be
prepared to use greater force
to overcome the additional
resistance
• Allow a minimum of 24 inches
(610 mm) clearance from the
bottom of the hook stick to
the ground for uninterrupted
hookstick travel.
CLOSING SWITCH
• To close the BP3 switch, place
a hookstick in the pull ring on
the blade and rotate the blade
to an intermediate position as
shown in Figure 6.
• Turn head and look away from
the switch.
• Quickly, firmly and without
hesitation drive the switch to
the closed position.
• Carefully remove the
hookstick from the pull ring to
avoid opening the switch.
High Voltage Electrical Arc Hazard
Can cause death, severe personal injury or
property damage.
Close the by-pass blade before opening either
of the two disconnect blades. Failure to do so
will result in an electrical arc.
WARNING
!
• The BP3 switch is properly
closed when the blade hook
is fully engaged with the latch
portion of the blade stop as
shown in Figure 7.
• Visually check each switch
blade for proper latching.
