Unpacking
Carefully unpack the transfer switch. Inspect closely for
any damage that might have occurred during shipment.
The purchaser must file with the carrier any claims for
loss or damage incurred while in transit.
Check that all packing material is completely removed
from the switch prior to installation.
Equipment Description
This automatic transfer switch is used for transferring
electrical load from a utility (normal) power source to a
generator (standby) power source. Transfer of electrical
loads occurs automatically when the utility power source
has failed or is substantially reduced and the generator
source voltage and frequency have reached an
acceptable level. The transfer switch prevents electrical
feedback between two different power sources (such as
the utility and generator sources) and, for that reason,
codes require it in all standby electric system installations.
The transfer switch consists of a transfer mechanism,
utility service disconnect circuit breaker (if equipped), and
a Smart A/C module incorporating fuses and two terminal
blocks for transfer switch connections.
This UL/CUL listed transfer switch has locking provisions
for the utility entry cabinet. In addition, it has a lockout/
tagout provision for the service entrance circuit breaker.
Transfer Switch Mechanism
See Figure 2-1. This switch is used with a single-phase
system when the single-phase neutral line is to be
connected to a neutral lug and is not to be switched.
Solderless, screw-type terminal lugs are standard.
The conductor size range is as follows:
This transfer switch is suitable for control of motors, electric
discharge lamps, tungsten filament and electric heating
equipment where the sum of motor full load ampere ratings
and the ampere ratings of other loads do not exceed the
ampere rating of the switch and the tungsten load does not
exceed 30 percent of the switch rating.
This UL/CUL listed transfer switch is for use in optional
standby systems only.
A 100A rated switch is suitable for use on circuits capable
of delivering not more than 10,000 RMS symmetrical
amperes, 250 VAC maximum, when protected by a 100A
maximum circuit breaker (Siemens types QP or BQ) or
150A maximum circuit breaker (Square D Q2,
Westinghouse CA-CAH, General Electric TQ2 and
Siemens QJ2).
A 200A rated switch is suitable for use on a circuit
capable of 22,000 RMS symmetrical amperes, 240 VAC
when protected by a circuit breaker without an adjustable
short time response or by fuses.

Transfer Switch Data Decal
See Figure 2-2 . A data decal is permanently affixed to the
transfer switch enclosure. Use this transfer switch only
with the specific limits shown on the data decal and on
other decals and labels that may be affixed to the switch.
This will prevent damage to equipment and property.
When requesting information or ordering parts for this
equipment, make sure to include all information from the
data decal.
For future reference, record the Model and Serial numbers
in the space provided on the front cover of this manual.
Figure 2-2. Data Decal Location
Transfer Switch Enclosure
The standard switch enclosure is a National Electrical
Manufacturer’s Association (NEMA) and UL/CUL 3R
type. UL/CUL and NEMA 3R (indoor/outdoor rated) type
enclosures primarily provide a degree of protection
against falling rain and sleet; are undamaged by the
formation of ice on the enclosure.
Safe Use of Transfer Switch
Before installing, operating or servicing this equipment,
read the Safety Rules carefully. Comply strictly with all
Safety Rules to prevent accidents and/or damage to the
equipment. The manufacturer recommends that a copy
of the Safety Rules be posted near the transfer switch.
Also, be sure to read all instructions and information
found on tags, labels and decals affixed to the
equipment.
Two publications that outline the safe use of transfer
switches are the following:
•Canadian Electrical Code CE; CSA C22.1
•NFPA 70E: Standard for Electrical Safety In The
Workplace
•UL/CUL 1008: Standard for Safety—Automatic
Transfer Switches
NOTE: It is essential to use the latest version of any
standard to guarantee correct and current information.
Load Management Options
Load management systems are designed to work
together to prevent a generator from being overloaded by
large appliance loads. A Smart A/C Module (SACM) is
provided as standard equipment with this switch. An
optional Smart Management Module (SMM) is also
available.
