• Never work on this equipment while physically or  
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
nonconducting 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  
circuit must be disabled before working on or  
around the generator or transfer switch. For that  
purpose, a SAFETY DISCONNECT is provided  
inside the transfer switch. Always set that switch  
to its MANUAL position before working on the  
equipment. 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  
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  
application, or improper procedures.

Every effort has been expended to make sure that the  
contents of this manual are both accurate and  
current. Generac, however, reserves the right to  
change, alter or otherwise improve the product at any  
time without prior notice.  
1.4 TRANSFER SWITCH ENCLOSURE  
The standard switch enclosure is a National  
Electrical Manufacturer’s Association (NEMA) 3R  
type. NEMA 3R type enclosures primarily provide a  
degree of protection against falling rain and sleet;  
undamaged by the formation of ice on the  
enclosure.  
1.2 EQUIPMENT DESCRIPTION  
The automatic transfer switch is used for  
transferring critical electrical load from a UTILITY  
(Normal) power source to  
a
EMERGENCY  
(STANDBY) power source. Such a transfer of  
electrical loads occurs automatically when the  
UTILITY power source has failed or is substantially  
reduced and the EMERGENCY 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 EMERGENCY sources) and, for that reason,  
codes require it in all standby electric system  
installations.  
1.5 SAFE USE OF TRANSFER SWITCH  
Before installing, operating or servicing this  
equipment, read the SAFETY RULES (inside front  
cover) carefully. Comply strictly with all SAFETY  
RULES to prevent accidents and/or damage to the  
equipment. Generac 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.  
The transfer switch consists of a solid state  
intelligence circuit, a transfer mechanism and a  
control panel.  
Two publications that outline the safe use of transfer  
switches are the following:  
1.3 TRANSFER SWITCH DATA DECAL  
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.

Section 2 — Installation  
Generac GTS “W” Type Transfer Switch  
Wiring diagrams and electrical schematics are  
provided in this manual. Power source and load  
connections are made at a transfer mechanism,  
inside the switch enclosure.  
2.1 INTRODUCTION TO INSTALLATION  
This equipment has been wired and tested at the  
factory. Installing the switch includes the following  
procedures:  
• Mounting the enclosure.  
2.4.1 2-POLE MECHANISM  
• Connecting power source and load leads.  
• Connecting the generator start circuit.  
• Connecting any auxiliary contact (if needed)  
• Installing/connecting any options and accessories.  
Testing functions.  
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.  
Figure 2.1 — Typical 2-Pole Transfer Mechanism  
(100 Amp Shown)  
2.2 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.  
2.3 MOUNTING  
Mounting dimensions for the transfer switch  
enclosure are in this manual. Enclosures are  
typically wall-mounted. See “Mounting Dimensions”.  
Handle transfer switches carefully when  
installing. Do not drop the switch. Protect the  
switch against impact at all times, and against  
!
construction grit and metal chips. Never  
install a transfer switch that has been  
damaged.  
Solderless, screw-type terminal lugs are standard.  
The conductor size range is as follows:  
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.  
Switch Rating  
Wire Range  
200A  
#4-400 MCM  
Conductor sizes must be adequate to handle the  
maximum 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  
conductors are used, apply corrosion inhibitor to  
conductors. 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)  
power supplies before trying to connect  
power source and load lines to the transfer  
switch. Supply voltages are extremely high  
and dangerous. Contact with such high  
voltage power supply lines causes extremely  
hazardous, possibly lethal, electrical shock.  
All power cables should enter the switch next to the  
transfer mechanism terminals.

2.6 AUXILIARY CONTACTS  
If desired, there are Auxiliary Contacts on the  
transfer switch to operate customer accessories,  
remote advisory lights, or remote annunciator  
devices. A suitable power source must be connected  
to the COMMON (C) terminal. See Figure 2.3.  
Use a torque wrench to tighten the  
conductors, being sure not to overtighten, or  
damage to the switch base could occur. If  
undertightened, a loose connection would  
result, causing excess heat which could  
damage the switch base.
