Summary & Introduction
Introduction
The EV is a three insulator, vertical break switch that is opened and closed by rotation of the
inside, hinge, insulator. The EV can be used for any conventional air break switch application,
including disconnecting and sectionalizing lines and isolating or by-passing equipment. Upright
mounted EV’s are equipped with arcing horns to protect the jaw contacts from pitting or metal
erosion when switching low current values on short runs of bus, ones, and transformer
excitation currents.
Type EVB – A bronze and copper version of the aluminum EV, for application where an
aluminum disconnect would be undesirable.
The installation procedure for all mounting positions and operating schemes are similar and
explained herein. A system of pipes, bearing, and adjustable length arms are utilized to open
and close the switch from a ground level operator.
All photographs and sketches in this manual are for illustration purposes only and may not be to
scale. Refer to the Unit Assembly drawing or the Operating Mechanism drawing provided with
each disconnect switch for specific details. During installation, it may be necessary to make
adjustments other than those described in this manual. Contact your local representative or the
factory if questions should arise.
Southern States After Sales and Service Department is available for field installation assistance
along with providing parts support for all Southern States products.

Product Description
Product Description
Typical Disconnect Switch
Installation of this type switch consists of partial disassembly:
•Removal of live parts from base
•Mounting the insulators to the base
•Mounting the live parts to the insulators
•Hoisting the assembled switch to the structure
Only after the switch is mounted on the structure should adjustments be made. When the switch
is assembled in this manner, it is imperative that the switch base is bolted to a level surface of
sufficient strength and stability to prevent overturn. Metal sawhorses, or their equivalent should
be constructed for this purpose.
An alternate method is to by-pass the ground assembly and mount the switch directly on the
structure. To do this, simply omit paragraph 1.4 (page 8) and mount the switch base to the
structure after checking the Operating Mechanism drawing for proper positioning. All other steps
will remain the same.
DO NOT change factory settings.

Receiving, Handling, & Storage
Receiving, Handling, & Storage
Receiving & Unpacking
Unpack the equipment and check for damages or shortages immediately. The bill-of-materials
from the Unit Assembly (switch) and Operating Mechanism drawings should be used for this
purpose. If damage or a shortage is noted, file a claim immediately with the carrier and contact
the factory.
Storage
All components of the EV vertical break disconnect switch are suitable for outdoor use and do
not have any special storage requirements. If a motor operator is furnished be sure to connect
the heater circuit, using the provided external wiring, while the unit is in storage. Discard the
wiring upon installation.
Typical crating is intended for storage less than 1 year. If long term storage is required please
notify factory at time of order placement so that special crating can be used.

Installation & Adjustment Procedures
Installation & Adjustment Procedures
Assembly
1. Preferred Switch Assembly Method
1.1. When convenient, but before opening the switch, screw the corona ball into the blade
tip securely.
1.1.1. Place a few drops of LOCTITE, or equivalent, on the stem of the corona ball
before attachment. Do not use the ball as a wrench; instead, use a pipe wrench
on the stem to screw it into the socket in the blade tip.
1.1.2. Open the switch completely by rotating the switch arm clockwise as shown in
Figure 2.
- HIGH PRESSURE SPRINGS! The switch has
powerful counterbalance springs. Unless it is completely open, it
will jackknife violently when the mounting bolts are loosened. For
personnel and equipment safety, open the switch completely
before attempting to remove bolts.
Figure 2: Switch Arm Detail

Installation & Adjustment Procedures
1.1.3. Make reference marks on the parts shown in Figure 3to ensure correct
reassembly.
Figure 3: Reference Marks Location
1.2. Remove the jaw. Discard the steel channel shipping spacer, but retain the ½” circular
spacer for later use. See Figure 4.
Figure 4: Jaw Removal

Page 7 of 19
Installation & Adjustment Procedures
1.3. With the switch fully open, carefully remove the hinge and yoke assembly as shown in
Figure 5. Discard the steel channel shipping spacers.

Installation & Adjustment Procedures
1.4. Place the base on a firm, level surface. It may be necessary to construct saw horses
for this purpose. Additionally, the temporary mounting should be stable and well-
anchored to prevent overturn of the switch.
Figure 6: Insulator Mounting
1.4.1. Mount the insulators as shown in Figure 6. Make sure that all insulators are the
same height above the base. If necessary, adjust the jack screws to achieve this.
See Figure 7.
Figure 7: Jack Screw Adjustment

Page 9 of 19
Installation & Adjustment Procedures
1.4.1.1. The best method to mount the end insulators is to remove the top
nuts from the jack screws and remove the mounting adaptors. The
adaptors can then be bolted directly to the bottom of the insulators
without interference problems with a socket wrench. Lift the
insulator stacks to the base as a completed unit and replace the jack
screw nuts.
1.4.1.2. The center insulator can be mounted without interference problems.
1.4.1.3. Plumb both end insulators. They must be perpendicular to both the
long and short axis.
1.4.2. It is essential that the rotating insulator move about its own axis in a uniform
manner without “wobble”. Follow the procedure in Figure 8to achieve concentric
rotation.
Step One
Make a marker of scrap lumber or metal and
attach it to the end insulator to use for a
reference point.
Place the reference point over the center of the
rotating insulator. The rotating insulator should
be up against a bearing stop.
Step Two
Rotate the insulator to the opposite bearing stop.
Observe for eccentric rotation (“wobble”).
Step Three
If the insulator has wobbled during rotation, leave
it against the bearing stop in step two. Use the
jack screws that mount the rotating insulator to
the bearing to tilt it back one half the distance to
the reference point on the marker.
Step Four
Rotate the insulator back to the beginning
position. Loosen the marker and place the
reference point over the center of the insulator
again. Repeat the last three steps until the
insulator rotates true (up to ½” wobble is
acceptable).
This method works whether the rotating insulator
is out of adjustment axially, laterally or any
combination in between.
Once the center stack rotates true, do not
readjust. Make all subsequent adjustments to the
other two insulator stacks as required.
Figure 8: Adjusting the rotating insulator for concentric rotation

Page 10 of 19
Installation & Adjustment Procedures
TIMESAVING TIP for mounting live parts when hardware must be placed between the insulator and the
live parts: Use two studs of sufficient length to allow later removal (easily made by cutting the heads off
two bolts) to align the parts. Bolt the live parts down with mounting bolts, using the two free holes; then
remove the studs and screw in the other two bolts.
This procedure can cut a significant amount of time from installation.
