mentally fatigued.  
• Keep the transfer switch enclosure door closed  
and bolted at all times. Only qualified personnel  
should be permitted access to the switch interior.  
• In case of an accident caused by electric shock,  
immediately shut down the source of electrical  
power. If this is not possible, attempt to free the  
victim from the live conductor but AVOID DIRECT  
CONTACT WITH THE VICTIM. Use a nonconduct-  
ing implement, such as a rope or board, to free  
the victim from the live conductor. If the victim  
is unconscious, apply first aid and get immediate  
medical help.  
• When an automatic transfer switch is installed for  
a standby generator set, the generator engine may  
crank and start at any time without warning. To  
avoid possible injury that might be caused by such  
sudden start-ups, the system’s automatic start cir-  
cuit must be disabled before working on or around  
the generator or transfer switch. Turn the genera-  
tor’s AUTO/OFF/MANUAL switch to OFF. Turn the  
generator’s main circuit breaker OFF. Then place  
a “DO NOT OPERATE” tag on the transfer switch  
and on the generator. Remove the Negative (Neg) or  
(–) battery cable.

1.1 INTRODUCTION  
1.3 TRANSFER SWITCH DATA LABEL  
A DATA LABEL is permanently affixed to the transfer  
switch enclosure. Use this transfer switch only with  
the specific limits shown on the DATA LABEL and  
on other decals and labels that may be affixed to the  
switch. This will prevent damage to equipment and  
property.  
This manual has been prepared especially for the  
purpose of familiarizing personnel with the design,  
application, installation, operation and servicing of  
the applicable equipment. Read the manual carefully  
and comply with all instructions. This will help to  
prevent accidents or damage to equipment that might  
otherwise be caused by carelessness, incorrect appli-  
cation, or improper procedures.  
When requesting information or ordering parts for this  
equipment, make sure to include all information from  
the DATA LABEL.  
Every effort has been expended to make sure that the  
contents of this manual are both accurate and cur-  
rent. The manufacturer reserves the right to change,  
alter or otherwise improve the product at any time  
without prior notice.  
Record the Model and Serial numbers in the space  
provided below for future reference.

1.2 EQUIPMENT DESCRIPTION  
The automatic transfer switch is used for transferring  
critical electrical loads from a UTILITY (NORMAL)  
power source to an EMERGENCY (GNERATOR)  
power source.  
The transfer switch prevents electrical feedback  
between the UTILITY and EMERGENCY sources. For  
that reason, electrical codes require a transfer switch  
in all standby electric system installations.  
1.4 TRANSFER SWITCH ENCLOSURE  
The standard switch enclosure is a National Electrical  
Manufacturer’s Association (NEMA) and UL 3R type.  
UL and NEMA 3R type enclosures primarily provide  
a degree of protection against falling rain and sleet;  
undamaged by the formation of ice on the enclosure.  
When the transfer switch is connected to the engine  
generator control panel, the control panel constantly  
monitors the UTILITY voltage and controls the opera-  
tion of the transfer switch.  
Should the UTILITY voltage drop below a preset value,  
and remain at this low voltage for a preset amount of  
time, the generator cranks and starts. After the gen-  
erator starts, the transfer switch transfers the load  
circuits to the generator, the generator then supplies  
the loads. When UTILITY returns above a preset level  
the load is transferred back to the UTILITY and the  
generator shuts down.  
1.5 SAFE USE OF TRANSFER SWITCH  
Before installing, operating or servicing this equip-  
ment, read the SAFETY RULES (inside front cover)  
carefully. Comply strictly with all SAFETY RULES  
to prevent accidents and/or damage to the equip-  
ment. The manufacturer recommends a copy of the  
SAFETY RULES are made and posted near the trans-  
fer 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:  
• NFPA 70; National Electrical Code  
• UL 1008, STANDARD FOR SAFETY-AUTOMATIC  
TRANSFER SWITCHES  
NOTE:  
It is essential to use the latest version of any stan-  
dard to ensure correct and current information.

Section 2 — Installation  
RTS “W” Type Transfer Switch  
2.4.1 2-POLE MECHANISM  
2.1 INTRODUCTION TO INSTALLATION  
This equipment has been wired and tested at the  
factory. Installing the switch includes the following  
procedures:  
These switches (Figure 2.1) are 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.  
• Mounting the enclosure.  
• Connecting utility and generator power source  
Figure 2.1 — Typical 2-Pole Transfer Mechanism  
(400 Amp Shown)  
leads.  
• Connecting the load leads.  
• Connecting any auxiliary contact (if needed)  
• Installing/connecting any options and accessories.  
Testing functions.  
2.2 UNPACKING  
Carefully unpack the transfer switch. Inspect closely  
for any damage that might have occurred during ship-  
ment. 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.  
2.3 MOUNTING  
Mounting dimensions for the transfer switch enclo-  
sure are in this manual. Enclosures are typically wall-  
mounted. See the “Mounting Dimensions” drawing.  
Handle transfer switches carefully when install-  
ing. Do not drop the switch. Protect the switch  
against impact at all times, and against construc-  
tion grit and metal chips. Never install a transfer  
switch that has been damaged.  
Install the transfer switch as close as possible to the  
electrical loads that are to be connected to it. Mount  
the switch vertically to a rigid supporting structure.  
To prevent switch distortion, level all mounting  
points. If necessary, use washers behind mounting  
holes to level the unit.  
Solderless, screw-type terminal lugs are standard.  
The conductor size range is as follows:  
Switch Rating  
Wire Range  
(1) #4-600 MCM or  
(2) 1/0-250 MCM  
400A  
Conductor sizes must be adequate to handle the max-  
imum current to which they will be subjected; based  
on the 75°C column of tables, charts, etc. used to size  
conductors. The installation must comply fully with  
all applicable codes, standards and regulations.  
2.4 CONNECTING POWER SOURCE  
AND LOAD LINES  
DANGER  
Before connecting wiring cables to terminals, remove  
any surface oxides from the cable ends with a wire  
brush. All power cables should enter the switch next  
to transfer mechanism terminals. If ALUMINUM con-  
ductors are used, apply corrosion inhibitor to con-  
ductors. Tighten terminal lugs to the torque values as  
noted on the decal located on the inside of the door.  
After tightening terminal lugs, carefully wipe away  
any excess corrosion inhibitor.  
Make sure to turn OFF both the UTILITY  
(Normal) and EMERGENCY (Standby generator)  
power supplies before trying to connect power  
source and load lines to the transfer switch.  
Supply voltages are extremely high and danger-  
ous. Contact with such high voltage power sup-  
ply lines causes extremely hazardous, possibly  
lethal, electrical shock.  
Wiring diagrams and electrical schematics are pro-  
vided in this manual. Power source and load connec-  
tions are made at the transfer mechanism, inside the  
switch enclosure.  
All power cables should enter the switch next to the  
transfer mechanism terminals.
