• 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. Always set the  
Auto-Off-Manual switch to its OFF position before  
working on the equipment. Then place a “DO NOT  
OPERATE” tag on the transfer switch and on the  
generator.

Section 1 — General Information  
Generac 100 Amp Transfer Switch  
1.1 INTRODUCTION  
1.3 TRANSFER SWITCH RATINGS  
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 careful-  
ly 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.  
DECAL  
Affixed to the transfer switch door is a RATINGS  
DECAL. Use the transfer switch only within the specif-  
ic limits shown on the RATINGS DECAL and on other  
decals and labels that may be affixed to the switch.  
This prevents damage to equipment and possible  
injury to personnel, and provides long and trouble-free  
life for the equipment.  
Every effort has been expended to make sure that the  
contents of this manual are both accurate and cur-  
rent. Generac, however, reserves the right to change,  
alter or otherwise improve the product at any time  
without prior notice.  
When requesting information or ordering parts for this  
equipment, make sure to include all information from  
the RATINGS DECAL.  
1.4 TRANSFER SWITCH ENCLOSURE  
The standard switch enclosure is a National  
Electrical Manufacturer’s Association (NEMA) 1 type.  
NEMA 1 type enclosures primarily provide protection  
against contact with the enclosed equipment and  
against a limited amount of falling dirt.  
1.2 EQUIPMENT DESCRIPTION  
The pre-packaged transfer switch is designed to use  
with pre-packaged standby generator control panels.  
It is used for transferring critical electrical loads  
from a NORMAL (utility) power source. Such a trans-  
fer of loads occurs automatically when the NORMAL  
power source fails or is subsequently reduced and  
the STANDBY source voltage and frequency have  
reached an acceptable level. The transfer switch pre-  
vents electrical feedback between two different power  
sources (such as the NORMAL and STANDBY  
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 equip-  
ment, 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 you make a copy of the SAFE-  
TY RULES and post them near the transfer switch.  
Also, be sure to read all instructions and information  
you may find on tags, labels and decals affixed to the  
equipment.  
Once the transfer is completed, the STANDBY power  
source then powers electrical loads connected to the  
transfer switch. When NORMAL source voltage  
above an acceptable (preset) level has been restored,  
voltage sensor action in the pre-packaged control  
panel initiates re-transfer back to NORMAL power  
source. After this re-transfer, the controller signals  
to open the start circuit to the generator, which shuts  
down the engine. The controller is then “armed” and  
ready for the next drop in NORMAL source voltage.  
Two publications that outline the safe use of transfer  
switches are the following:  
• National Electrical Code  
• UL 1008, STANDARD FOR SAFETY-AUTOMATIC  
TRANSFER SWITCHES  
NOTE: Keep in mind the pre-packaged transfer  
switch is without any kind of electronic controls. It  
receives signals solely from the controller contained  
in the pre-packaged control panel.

Section 2 — Installation  
Generac 100 Amp Transfer Switch  
2.1 INTRODUCTION TO INSTALLATION  
This equipment has been wired and tested at the facto-  
ry. Installing the switch includes the following proce-  
dures:  
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 pre-  
vent switch distortion, level all mounting points. If nec-  
essary, use washers behind mounting holes to level the  
unit.  
• Mounting the enclosure.  
• Connecting power source and load leads.  
• Connecting control wiring.  
• Connecting any auxiliary contact (if needed)  
• Installing/connecting any options and accessories.  
Testing functions.  
2.4 CONNECTING POWER SOURCE AND  
LOAD LINES  
DANGER  
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.  
Make sure to turn OFF both the normal (Utility)  
and standby (generator) power supplies before  
trying to connect power source and load lines to  
the transfer switch. Supply voltages are extreme-  
ly high and dangerous. Contact with such high  
voltage power supply lines causes extremely haz-  
ardous, possibly lethal, electrical shock.  
Check that all packing material is completely removed  
from the switch prior to installation.  
Attach any lifting device to the transfer switch mounting  
holes or brackets only. DO NOT LIFT THE SWITCH AT  
ANY OTHER POINT.  
Wiring diagrams and electrical schematics are provided  
in this manual. Power source and load connections are  
made at a transfer mechanism, inside the switch enclo-  
sure.  
2.3 MOUNTING  
Transfer switch components are generally mounted in a  
standard NEMA 1 type enclosure (Figure 2.1).  
2.4.1 2-POLE MECHANISM  
This switch (Figure 2.2) is used with a single phase sys-  
tem, when the single phase NEUTRAL line is to be con-  
nected to a Neutral Lug and is not to be switched.  
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.

Generac 100 Amp Transfer Switch  
3.1 FUNCTIONAL TESTS AND  
ADJUSTMENTS  
DANGER  
Failure to turn OFF all power voltage supplies to  
the transfer switch before attempting manual  
operation results in extremely hazardous and pos-  
sibly fatal electrical shock.  
Following transfer switch installation and interconnec-  
tion, inspect the entire installation carefully. A compe-  
tent, qualified electrician should make the inspection.  
The installation should comply strictly with all applica-  
ble codes, standards, laws and regulations. All electri-  
cal connections must be correct and in compliance with  
applicable codes and standards.  
4. Remove the manual transfer handle from the enclo-  
sure.  
5. Place open slot of the manual transfer handle on the  
small tab of the transfer switch operating lever  
(Figure 3.1).  
6. Pull manual transfer handle downward. If handle is  
down, LOAD is connected to STANDBY power  
source. If handle is up, LOAD is connected to UTIL-  
ITY power.  
7. Move the transfer switch main contact to both posi-  
tions several times. Leave the transfer switch in the  
UTILITY position and connect LOAD to the UTILITY  
power source (manual operation lever is up).  
Make sure the standby generator is ready.  
This  
includes checking engine oil level, coolant level, fuel  
supply, batteries and other items specified in the  
Owner’s Manual for specific generators.  
Complete all functional tests as outlined in the Post  
Installation Start-Up Adjustments section. Do this  
before placing the transfer switch into service.  
Functional tests of the transfer switch include these  
tests: (a) Manual Operation, (b) Voltage Checks and (c)  
Electric Operation.  
Figure 3.1 — Transfer Switch Operation (“V” Type)  
To avoid damaging the transfer switch, perform  
functional test in the exact order given.  
!
Before proceeding with functional tests, read and be  
sure you understand all instructions in this section.  
Also, read the instructions and information on tags and  
decals affixed to the transfer switch. Note any options  
and accessories that might be installed or provided with  
the switch and review their operation.  
DANGER  
Do not attempt manual operation of the transfer  
switch until after all power voltage supplies to  
the switch have been turned off. Failure to turn  
off power voltage supplies may result in danger-  
ous and possibly fatal electrical shock.  
3.2 MANUAL OPERATION  
Instructions for “V” type transfer switches: Test manu-  
al operation as follows:  
1. Check that the generator’s Auto-Off-Manual switch  
has been set to the OFF position.  
2. Turn Off the UTILITY power supply to the transfer  
switch, using whatever means provided (such as the  
UTILITY source main line circuit breaker).  
3. Set the generator’s main circuit breaker to its Off or  
OPEN position.

3.3 TRANSFER SWITCH VOLTAGE  
3.4 GENERATOR TESTS UNDER LOAD  
1. Set the generator’s main circuit breaker to its OFF  
or OPEN position.  
CHECKS  
1. Turn ON the UTILITY power supply to the transfer  
switch with whatever means provided (such as the  
UTILITY main line circuit breaker).  
2. Turn OFF utility power to the transfer switch.  
3. Manually move the transfer switch main contacts to  
their STANDBY position.  
4. To start the generator, set the Auto-Off-Manual  
switch to MANUAL. When engine starts, let it stabi-  
lize for a few minutes.  
5. Turn the generator’s main circuit breaker to its ON  
or CLOSED position. The generator now powers all  
LOAD circuits. Check generator operation under  
load as follows:  
• Turn ON electrical loads to the full rated  
wattage/amperage capacity of the generator. DO  
NOT OVERLOAD.  
DANGER  
Proceed with caution. The transfer switch is now  
electrically hot. Contact with live terminals  
results in extremely hazardous and possibly fatal  
electrical shock.  
2. With an accurate AC voltmeter, check for correct  
voltage across terminal lugs N1 and N2; N1 to NEU-  
TRAL; and, finally, N2 to NEUTRAL (see Wiring  
Diagram on Page 8).  
• With maximum rated load applied, check voltage  
and frequency across transfer switch terminals E1  
and E2. Voltage should be greater than 230 volts;  
frequency should be greater than 58 Hz.  
• Let the generator run under rated load for at least  
30 minutes. With the unit running, listen for  
unusual noises, vibration, overheating, etc., that  
might indicate a problem.  
3. When certain that UTILITY supply voltage is correct  
and compatible with transfer switch ratings, turn  
OFF the UTILITY supply to the transfer switch.  
4. On the generator panel, set the Auto-Off-Manual  
switch to MANUAL position. The generator should  
crank and start.  
5. Let the generator stabilize and warm up at no-load  
for at least five minutes.  
6. When checkout under load is complete, set the gen-  
erator’s main circuit breaker to its OFF or OPEN  
position.  
6. Set the generator’s main circuit breaker (CB1) to its  
ON or CLOSED position.  
7. Let the generator run at no-load for several minutes.  
Then, shut down by setting the Auto-Off-Manual  
switch to its OFF position.  
8. With the manual transfer handle, move the switch’s  
main contacts back to their utility position, i.e., load  
connected to utility power supply. The handle and  
operating lever of the transfer switch should be in  
the up position.  
9. Turn on the utility power supply to the transfer  
switch, using whatever means provided (such as a  
utility main line circuit breaker). The utility power  
source now powers the loads.  
DANGER  
Proceed with caution. Generator output voltage  
is now being delivered to transfer switch termi-  
nals. Contact with live terminals results in  
extremely dangerous and possibly fatal electrical  
shock.  
7. With an accurate AC voltmeter and frequency meter,  
check the no-load, voltage and frequency meter at  
transfer switch terminal lugs E1, E2 and NEUTRAL.  
Readings should be as follows:  
a. Frequency................................61-63 Hz  
b. Terminals E1 and E2..............242-253 volts  
c. Terminal E1 to Neutral ..........121-126 volts  
d. Terminal E2 to Neutral ..........121-126 volts  
8. Set the generator’s main circuit breaker (CB1) to its  
OFF or OPEN position.  
10. Set the generator’s main circuit breaker to its ON or  
CLOSED position.  
11. Set the generator’s Auto-Off-Manual switch to its  
AUTO position. The system is now set for fully  
automatic operation.  
9. To shut down the generator, set its Auto-Off-Manual  
switch to its OFF position.  
NOTE:  
Do NOT proceed until generator AC output voltage  
and frequency are correct and within stated lim-  
its. If the no-load voltage is correct but no-load  
frequency is incorrect, the engine governed speed  
probably requires adjustment. If no-load frequen-  
cy is correct but voltage is not, the voltage regu-  
lator may require adjustment.
