Summary & Introduction
Introduction
The Southern States Type EC-1V is a three phase, group operated, center break “vee” air
disconnect switch constructed primarily of high strength aluminum. Applications for these switches
included disconnecting and sectionalizing of lines, and isolating or bypassing other electrical
equipment. Poles can be mounted in a horizontal “upright,” vertical, or under-hung position. The
switch can be operated using a manual operator or electrical motor operator (Operating
Mechanism).
For easy installation, all models use jack screws which provide infinite adjustments and eliminate
time consuming shimming of insulator stacks.
The installation procedure for all mounting positions and operating schemes is similar and explained
herein. A system of pipes, bearing, and adjustable length arms is utilized to open and close the
switch from a ground level operator.
The instructions contained within this manual are necessary for the safe installation, maintenance,
and operation of the EC-1V switch. A qualified person, familiar with this of type equipment, should
carefully read and follow the instructions.
These instructions are intended to provide a general guideline for the installation, adjustment, and
maintenance of the EC-1V switch. It is not possible to cover all details, equipment variations, and
potential conditions. Contact Southern States, LLC in the event conditions associated with a specific
application are not sufficiently addressed.
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.

Receiving, Handling & Storage
Unpacking
Unpack the equipment and check for damages or material shortages immediately. The bill-of-
material 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 EC-1 aluminum center side break disconnect switch are suitable for outdoor
use and do not have any special storage requirements. Keep bearings out of standing water. Keep
upright and support live parts with base. 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.
These switches are top-heavy and unstable unless bolted down. To prevent
personnel injury or equipment damage, use extreme care when uncrating.

Installation & Adjustment Procedures
Preferred Switch Assembly Method
The Type EC-1V center break Vee switch is normally shipped assembled on insulators. Control
components are packed separately. Installation consists of mounting the switch pole on the
structure and installing the operating linkage.
These instructions give the general procedure for adjusting EC-1V switches. It may be necessary to
make adjustments not described in the manual. If any questions should arise concerning the
installation or adjustment of its equipment, please call your local Southern States representative or
the factory direct.
1. Prior to mounting preassembled switches on the structure, each pole should be thoroughly
inspected for damage in shipment. If damage is noted, immediately file a claim with the carrier
and notify the factory.
2. Assemble the switch pole on the ground and hoist it to the structure as a complete unit.
4. Test each switch pole for free operation and blade alignment. When closed, the blades should
be in a straight line with the bearing stops touching (Figure 2). These stops can be adjusted if
necessary.
5. After mounting the switch, shimming the base or other minor adjustments may be necessary.
6. Using main sling attachment to the switch base only and auxiliary sling attachment to keep
the switch upright, mount the switches on the structure as shown on the plan view of the
operating mechanism drawing. Be sure to orient each pole with the switch operating arm in
the proper position. When lifting, positively lock the switch closed. This can be done by using
clamps, wire, or straps to keep the switch operating arm (”E” on Figure 1) hard against the
bearing stop.
7. When switch is mounted on the structure AND conductors are attached to terminal pads, check
each pole for proper contact. Switch blades must some together with the male blade contact
touching (not jamming) or within 1/16” of the blade stop in the female contact assembly.
If necessary, adjust the jack screws as described under “Contact Misalignments” in
the following section.
To prevent overturning during assembly, the switch base must be securely
attached to a level, stable platform.
Lift fully assembled pole unit by the base only. DO NOT lift the pole unit by the
live parts. Refer to

Installation & Adjustment Procedures
Figure 2: Contact Assembly
8. Preload the insulator as described under “Insulator Preload” in the following section.
9. If arcing horns are used, refer to Figure 3and the unit assembly drawing for installation.
Arcing horns should rub against the male contact with enough pressure to maintain contact
but not so hard as to cause binding. The horns can be bent if necessary to achieve proper
contact.

A – Male Contact
B – Blade Stop

Installation & Adjustment Procedures
Installation of the EC-1V When Shipped Unassembled
1. Prior to assembly, all components should be checked for any obvious damage in shipment.
If damage is noted, immediately file a claim with the carrier and notify the factory.
2. The preferred method of field assembly is to bolt the switch base directly to its mounting
structure and assemble the switch in place. Refer to the operating mechanism and the unit
assembly drawing to ensure proper positioning of the base.
−An alternative method is to assembly the switch on the ground and hoist to structure
as a completely assembled unit. To do this:
−Bolt the base to a firm, level surface sturdy enough to prevent overturn. These
switches are top-heavy and very unstable. To prevent possible personal injury or
equipment damage, select an assembly surface that will prevent overturn in both
planes, end-to-end and side-to-side.
3. Refer to the unit assembly drawing. Check jack screw dimensions for proper height. Be
certain that all four jack screws on each bearing are set correctly. Tighten jam nuts securely.
4. To install insulators, refer to the unit assembly drawing for proper orientation of parts. Only
one set of bearing stops (positioned on control end of base) is used. Position switch arm
directly on hub of bearing with bearing stops. Place an intrapole arm on top, being careful to
set at proper angle with respect to the switch arm when against the bearing stop. Bolt
insulators directly to the intrapole arm plate (Figure 4).

B – Switch Arm (in closed position)
C – Bearing Stop
D – Intrapole Arm
E – Insulator
F – Intrapole Linkage
G – Counterbalance Arm (for weights)

Page 11 of 25
Installation & Adjustment Procedures
5. Place counterbalance arm directly on the other bearing hub and other intrapole arm on top.
Be certain the angle between the two arms is set correctly. Bolt insulators directly to the
intrapole arm plate.
NOTE: Field assembly of switches with multiple unit insulator stacks is easier when the lowest unit
is mounted first and balance of units mounted to it rather than mount the entire stack as a single
unit.
6. Rotate insulator with switch arm clockwise (facing down) against the stop and attach
intrapole linkage. Be sure length of this linkage is properly set to dimension shown on
drawing.
7. Depending upon its application, this type switch will be counterbalanced either by weight or
by spring. Refer to unit assembly drawing and attach appropriate number of weights – or the
spring – to the counterbalance.
8. On top of stack with the switch arm only, securely bolt the male blade assembly in line with
length of the base.
9. On the other stack, securely bolt the female blade assembly. The switch will have to be
opened slightly to do this.
