Summary & Introduction 

Introduction 

 

Southern States Type EC-2V 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-2V 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-2V  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.

Distinctive signal words are used to indicate the degree of hazard that may be encountered by the user.  

Identification of the signal words and their definition follow: 

 

 

Indicates a potentially hazardous situation, which, if not avoided, could result 

in death or serious injury. 

 

Indicates an imminently hazardous situation, which, if not avoided, will result in 

death or serious injury. 

 

Indicates a potentially hazardous situation, which, if not avoided, may result in 

minor or moderate injury. It may also be used to alert against unsafe practices.
