DESCRIPTION
The Power Transfer System safely connects up to six vital
or essential household loads, such as the furnace fan,
freezer, refrigerator, water well pump, sump pump, or lights
to either the utility power or a portable generator. In the
event of a utility power failure, the homeowner can safely
select individual essential devices to be powered by an
outdoor portable generator. The power transfer system
will not permit connection to both utility and generator
power at the same time.
The Power Transfer System is easy for a licensed electrician
or qualified professional to install, safe for a homeowner to
operate, and will work with 240 Volt AC generators
factory equipped with a NEMA type L14-30R receptacle.
NOTE: The maximum load allowed through the Load
Manager™ switch is 7200 watts, 30 Amps at 240 VAC /
60 Amps at 120 VAC.
SAFETY RULES
Per National Electric Code, connection of a
generator to any electrical circuit normally powered
by an electric utility must be by means of approved
transfer switch equipment so as to isolate the
electrical circuit from the utility distribution system
when the generator is operating. Failure to isolate
the electrical circuits by such means may result in
injury or death to utility power workers due to
backfeed of electrical energy.
The Load Manager™ switch is suitable for use in
accordance with Article 702 of the National Electric
Code, ANSI/NFPA 70. This switch is suitable for use
on a circuit capable of delivering not more than
1000A RMS, symmetrical current, 125/250V, when
installed on the load side of appropriate branch
circuit. For indoor use only. The connection box is a
NEMA type 3R, intended for outdoor use.
1. A licensed electrician or qualified professional
(referred to herein as “installer”) must install
the power transfer system per local code.
2. During installation, the installer is required to remove
the cover from the building power distribution panel
(referred to herein as a ‘load center’.) To reduce the
risk of electrical shock, the Main circuit breaker must
be turned OFF while the load center cover is
removed.
3. DO NOT OVERLOAD THE GENERATOR.
Overloading a generator in excess of its rated wattage
capacity will trip generator circuit breakers.
4. Contrary to generator owner’s manual, always plug the
connecting cord set into the connection box and
generator BEFORE starting the generator. Always shut
the generator down before detaching the cord set.
5. PORTABLE GENERATORS ATTACHED TO
THIS POWER TRANSFER SYSTEM MUST BE
OPERATED OUTSIDE, in accordance with
warnings and instructions found in the generator’s
owner’s manual.
GENERATOR
COMPATIBILITY
Only use a generator that is
factory-equipped with a NEMA
L14-30R receptacle, shown in
Figure 18.
NEVER use a generator equipped
with a 3-prong 240V receptacle
because damage may occur in
connected appliances.

Procedure, step 21.
Items Not Shipped with Power Transfer System:
The following items, required for system installation, are
not included and must be provided by the installer:
1. Tools required for installation
2. Anchors and screws to mount the power transfer
system components and conduit.
3. Junction box(s), conduit, fittings, wire nuts, and
insulated copper wire for connecting the Load
Manager™ switch to the outside connection box.
PLAN THE INSTALLATION
The installer and the homeowner decide which circuits are
to be powered by the generator during a utility power
outage:
• The plan should ensure that no single circuit load
exceeds 15 Amps.
• The plan should also identify circuits that exceed the
15 Amp maximum.
• During generator operation, the homeowner should use
only necessary household items and to alternate use of
larger loads, such as water pump, electric skillet, or
furnace fan. The installer will instruct the homeowner in
appropriate load management techniques.
Three methods of determining loads are given.
Measure Actual Loads
The installer uses a clamp-on ammeter to measure each of
the actual desired loads to ensure each total circuit draws
less than 15 Amps.

Sum Loads from Data Plates
The installer inspects each desired device, notes current
consumption found on labels on each appliance, then adds
all loads on each circuit:
• The rated current of appliances and motors can usually
be found on a data plate or decal affixed to the device.
• The rated wattage of lights can be taken from light bulbs.
• Some electric motors, such as induction types, require
three times more power for starting than for running.
This surge of power lasts for only a few seconds when
starting such motors. Be sure to allow for starting load.
Estimate Loads
The third method estimates total circuit loads based on
information given in Figure 2.
INSTALLATION
PROCEDURE

OPERATING PROCEDURE
The Load Manager™ switch is equipped with six three-
position switches. The switch positions labeled “LINE” are
used for connecting the essential devices to the utility
power source. The switch positions labeled “OFF” are used
for load management. The switch positions labeled “GEN”
are used for connecting desired circuits to the generator
power source. The following sections describe appropriate
use of these Load Manager™ switches.
Switch To Generator Power
To switch to generator power after a utility power failure:
1. Ensure all Load Manager™ switches are in “LINE”
position, as shown in Figure 20.
2. Align the female socket of the connecting cord set
with the connection box receptacle’s mating male
prongs, as shown in Figure 21. Push cord set
connector in and twist clockwise to lock.
3. Align the male prongs on the other end of the cord set
with the mating female terminals of the generator’s
240V receptacle, as shown in Figure 22. Push in
connector and twist clockwise to lock.

Figure 21 — Connection Box Connection
Figure 22 — Align Connectors at Generator
11
Generac Portable Products Power Transfer System
6. At the Load Manager™ switch, switch desired circuits
from “LINE” position to “GEN” position (as shown in
Figure 23).
Load Management
The number of circuits that can be operated simultaneously
during a utility failure will depend on the wattage capacity of
your generator. Most portable generators do not have
the capacity to handle loads on all Load Manager™
switch circuits at the same time.
Review the load management plan developed with the
installer (see “Plan the Installation” on page 3). It may be
necessary to selectively turn on and off certain loads while
using generator power so that necessary appliances can be
operated safely.
The watt meters provided on the Load Manager™ monitor
the current draw through each set of three circuits. For
example, circuits “A”, “B”, and “C” are monitored by the
lower left meter. When switching loads to the GEN
position, watch the watt meter to ensure that maximum
current levels are not exceeded and that each meter’s load
is similar (balanced).
Switch To Utility Power
To revert from generator power to utility power
after utility power is restored:
1. At the Load Manager™ switch, place all switches in
“LINE” position, as shown previously in Figure 20.
2. Shut off the generator.
3. Disconnect the connecting cord set from the
generator and the connection box.
Testing
Following installation and periodically thereafter,
test the power transfer system as follows:
1. Ensure that all Load Manager™ switches are at “LINE”
position (see Figure 20).
2. Connect the connection cord set to the building’s
connector box (see Figure 21).
3. At the generator, connect the other end of the
connection cord set to the generator (see Figure 22).
4. Start the generator.
5. At the Load Manager™ switch, set the “A” switch to
“GEN” position, as shown in Figure 24. Verify that the
“A” circuit load is operating properly. Return the “A”
switch to the “LINE” position.
6. Repeat Step 5, above, for each of the other load
management circuits.
Circuit Breakers in Load Manager™
Switch
Individual Load Manager™ switch circuits “A” through “F”
are each protected by a 15 Amp circuit breaker. These
breakers are labeled “A”, “B”, “C”, and so forth, as seen in
Figure 24, for example. If an electrical load on one of these
circuits exceeds 15 Amperes, the Load Manager™ switch
circuit breaker will open.
To reset the Load Manager™ switch breaker:
1. Eliminate the overload condition.
2. Place the switch with the tripped circuit breaker in
the “OFF” or middle position.
3. Press in the circuit breaker button and observe that
the button remains in.
4. Place the switch that was in the OFF position back to
GEN (or LINE, if that is what is desired).

PLAN LA INSTALACIÓN
El instalador y el propietario del local decidirán qué
circuitos deberán ser alimentados por el generador durante
un corte en el suministro de energía eléctrica:
• El plan deberá garantizar que ninguna de las cargas de los
circuitos exceda los 15 Amps.
• El plan deberá identificar también aquellos circuitos que
excedan el nivel máximo de 15 Amps.
• Durante la operación del generador, el propietario de la
casa deberá utilizar sólo los enseres caseros necesarios y
alternar el uso de cargas mayores, tales como los de la
bomba del agua, el sartén eléctrico, o el ventilador del
horno. El instalador instruirá al propietario del local las
técnicas apropiadas de administración de cargas.
Ofrecemos tres métodos para determinar las cargas.
Medir las Cargas Actuales
El instalador utiliza un amperímetro para medir cada carga
deseada con el objetivo de asegurar que el total de los
circuitos sea menor a 15 Amps.
Sumar la Cargas de las Placas de Datos
El instalador inspecciona cada aparato deseado, observa el
consumo actual encontrado en las estiquetas de cada uno
de los enseres, y después añade todas las cargas a cada
circuito.
• La tasa de corriente para enseres y motores puede
encontrarse por lo general en la placa de datos pegada al
dispositivo.
• El wattaje de las luces puede medirse desde los focos de
luz.
NOTAS:
• Algunos motores eléctricos, tales como los de tipo de
inducción requiere tres veces más energía para iniciar la
operación que para sostenerla. Esta carga de energía
dura sólo unos segundos cuando se inicia dicho tipo de
motores. Asegúrese de permitir esta carga alta para
iniciar su funcionamiento.
Cargas Estimadas
El tercer método estima la carga total de circuito basados
en la información proporcionada en la Figura 26.

PROCEDIMIENTO DE
INSTALACIÓN
Interruptor del Load Manager™
Antes de quitar la cubierta del centro de carga, decida
donde colocará el interruptor del Load Manager™.
Sostenga el interruptor del Load Manager™ a una distancia
de aproximadamente 18 pulgadas desde la mitad del centro
de carga, tal y como se muestra en la Figura 27.
1. Cerciórese de que exista suficiente espacio para
colocar el interruptor del Load Manager™ y que sea
posible conectar el tubo flexible al centro de carga.
2. Identifique una ranura libre apropiada de 3/4" en el
centro de carga.
¡PELIGRO! Debe evitarse el contacto con
alambres y terminales dentro del centro de carga ya
que puede resultar en un choque eléctrico
peligroso. Antes de quitar la cubierta del centro de
carga, apague (OFF) el interruptor del circuito que
alimenta el centro de carga. Recuerde que los
alambres al lado del interruptor del circuito
principal son eléctricamente peligrosos.
3. Apague (OFF) el breaker del circuito principal del
centro de carga; después quite la cubierta del centro
de carga.
4. Remueva la ranura predeterminada. Todos los alambres
que se extienden desde el tubo flexible adherido al
interruptor del Load Manager™ através del agujero
vacío, tal y como se muestra en la Figura 28. Asegure
el conector del tubo al centro de carga con la tuerca
de seguridad incluida.
5. Fije el interruptor del Load Manager™ a la pared en la
posición seleccionada, tal y como se muestra en la
Figura 29.

6. Siguiendo el plan, determine la carga que será
conectada al circuito "A" del interruptor del Load
Manager™. Gire ese breaker del circuito del centro de
carga a su posición de apagado (OFF). Afloje el tornillo
que sostiene el alambre a su breaker y después
remueva el alambre. La Figura 30 muestra el alambre
de carga seleccionado removido de su circuito breaker.
7. Encuentre los alambre negro y rojos marcados "A" que
vienen desde el interruptor Load Manager™. Con
sumo cuidado, conduzca ambos alambres cerca del
breaker del circuito seleccionado. Corte y descubra el
alambre "A" e instálelo de manera apropiada en el
breaker del circuito.
8. Corte y descubra el alambre negro "A" para que
coincida con el alambre previamente removido del
breaker. Asegure el final del alambre a la tuerca del
alambre. Fije cuidadosamente los alambres al centro de
carga, tal y como se muestra en la Figura 31.
IMPORTANTE: El instalador nunca deberá cruzar las
guías de los alambres rojo y negro del interruptor Load
Manager™. Hacerlo puede invalidar la garantía y podría
ocasionar un daño significativo a los componentes del Load
Manager™ y al generador.
Asegúrese de que:
• El alambre ROJO del interruptor del Load Manager™
siempre esté conectado al breaker del circuito.
• El alambre NEGRO del interruptor Load Manager™
siempre esté conectado a carga.
¡PELIGRO! Deberá conectar los alambres del
interruptor del Load Manager™ tal y como se
describe aquí o corre el riesgo de provocar severos
daños al equipo o a usted mismo.
