• 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 nonconduct-
ing implement, such as a dry 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. Then place a “DO
NOT OPERATE” tag on the transfer switch and on
the generator. Remove the Negative (Neg) or (–) bat-
tery cable.

1.2 EQUIPMENT DESCRIPTION
The automatic transfer switch is used for transfer-
ring electrical load from a UTILITY (NORMAL) power
source to a EMERGENCY ( STANDBY) power source.
Such a transfer of electrical loads occurs automati-
cally 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.
1.4 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 and
is not damaged by the formation of ice on the
enclosure.
The transfer switch consists of a transfer mecha-
nism, a relay control, and a terminal strip for con-
nection of sensing wires.
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 that a copy of the SAFETY
RULES are posted near the transfer switch. Also, be
sure to read all instructions and information found
on tags, labels and decals affixed to the equipment.
This switch is suitable for control of motors, electric
discharge lamps, tungsten filament and electric heat-
ing 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.
Two publications that outline the safe use of transfer
switches are the following:
The transfer switch is for use in optional standby sys-
tems only.
• NFPA 70; National Electrical Code
• UL 1008, STANDARD FOR SAFETY-AUTOMATIC
TRANSFER SWITCHES
The transfer switch is suitable for use on a circuit
capable of 10,000 rms symmetrical amperes, 240
VAC when protected by a circuit breaker without an
adjustable short time response or by fuses.

2.4.1 2-POLE MECHANISM
‹
2.1 INTRODUCTION TO INSTALLATION
This equipment has been wired and tested at the fac-
tory. Installing the switch includes the following pro-
cedures:
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 power source and load leads.
• Connecting the generator start circuit.
• Connecting any auxiliary contact (if needed)
• Testing functions.
Figure 2.1 — Typical 2-Pole Transfer Mechanism
(200 Amp Shown)
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 “Installation Diagram”, Section 5.
Solderless, screw-type terminal lugs are standard.
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 dam-
aged.

Conductor sizes must be adequate to handle the max-
imum current to which they will be subjected to,
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.
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.
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.
2.4 CONNECTING POWER SOURCE
AND LOAD LINES
DANGER
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 volt-
age power supply lines causes extremely haz-
ardous, possibly lethal, electrical shock.
All power cables should enter the switch next to the
transfer mechanism terminals.
Use a torque wrench to tighten the conduc-
tors, being sure not to over tighten, or dam-
age to the switch base could occur. If not
Wiring diagrams and electrical schematics are pro-
vided in this manual. Power source and load connec-
tions are made at a transfer mechanism, inside the

3.4 GENERATOR TESTS UNDER LOAD
1. Set the generator's main circuit breaker to its
OFF or OPEN position.
2. Manually actuate the transfer switch main con-
tacts to their EMERGENCY (STANDBY) position.
Refer to Manual Operation (Section 3.2).
3. To start the generator, set the AUTO-OFF-
MANUAL switch to MANUAL. When engine starts,
let it stabilize for a few minutes.
4. Turn the generator's main circuit breaker to its
ON or CLOSED position. The generator now pow-
ers all LOAD circuits. Check generator operation
under load as follows:
DANGER
PROCEED WITH CAUTION. GENERATOR OUT-
PUT VOLTAGE IS NOW BEING DELIVERED TO
TRANSFER SWITCH TERMINALS. CONTACT
WITH LIVE TERMINALS RESULTS IN EXTREMELY
DANGEROUS AND POSSIBLY FATAL ELECTRI-
CAL SHOCK.
7. With an accurate AC voltmeter and frequency
meter, check the no-load, voltage and frequency.
Single-phase generator supply:
Measure across ATS terminal lugs E1 to E2. Also
check E1 to NEUTRAL and E2 to NEUTRAL.
a. Frequency ......................................60-62 Hertz
b. Terminals E1 to E2 ........................240-246 VAC
c. Terminals E1 to NEUTRAL ............120-123 VAC
d. Terminals E2 to NEUTRAL ............120-123 VAC
8. Set the generator’s main circuit breaker (CB1) to
its OFF or OPEN position.
•
Turn ON electrical loads to the full rated
wattage/amperage capacity of the generator.
DO NOT OVERLOAD.
•
With maximum rated load applied, check
voltage and frequency across transfer switch
terminals E1 and E2. Voltage should be
greater than 230 volts and frequency should
be greater than 59 Hertz.
9. Set the AUTO/OFF/MANUAL switch to the OFF
position to shut down the generator.
•
Let the generator run under rated load for at
least 30 minutes. With unit running, listen for
unusual noises, vibration, overheating, etc.,
that might indicate a problem.
NOTE:
Do NOT proceed until generator AC output voltage
and frequency are correct and within stated limits.
If the no-load voltage is correct but no-load fre-
quency is incorrect, the engine governed speed
probably requires adjustment. If no-load frequen-
cy is correct but voltage is not, the voltage regula-
tor may require adjustment.
5. When checkout under load is complete, set main
circuit breaker of the generator to its OFF or
OPEN position.
6. Let the generator run at no-load for several
minutes. Then, shut down by setting the AUTO-
OFF-MANUAL switch to its OFF position.
7. Move the switch's main contacts back to their
UTILITY position. For example, load connected to
UTILITY power supply. Refer to Manual
Operation (Section 3.2). Handle and operating
lever of transfer switch should be in UP position.
8. Turn on the utility power supply to transfer
switch, using whatever means provided (such as
a utility main line circuit breaker). The utility
power source now powers the loads.
9. Set the generator's AUTO-OFF-MANUAL switch to
its AUTO position. The system is now set for fully
automatic operation.
