This product must be installed in compliance with local residential wiring and electrical codes by a  
licensed electrician or qualified professional. Generac Portable Products is not responsible for  
damaged equipment, accidents, or personal injury caused by incorrect installation.  
Read this Safety Manual and Instructions BEFORE operating Power Transfer System.  
The Model 1403 Power Transfer System safely connects up to twelve essential household loads, such as the  
furnace fan, freezer, refrigerator, water well pump, sump pump, lighting or outlet circuits to either the utility power  
or a portable generator. In the event of a utility power failure, the homeowner can safely select devices to be  
powered by an outdoor portable generator. Self-contained load meters assist the operator when managing power  
loads. The power transfer system will not permit connection to both utility and generator power at the same time.  
The Model 1403 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  
14-50R receptacle.  
This manual contains important warnings and information. READ AND RETAIN FOR REFERENCE.

Generac Portable Products Power Transfer System  
Sum Loads from Data Plates  
1. A licensed electrician or qualified professional  
(referred to herein as “installer”) must install  
the power transfer system per local code.  
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.  
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.  
• The rated wattage of lights can be taken from light  
• Some electric motors, such as induction types,  
require about 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 this high starting load.  
Overloading a generator in excess of its rated  
wattage capacity will trip generator circuit  
Estimate Loads  
The third method estimates total circuit loads based on  
information given in Figure 1.  
4. 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.

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 or electric  
skillet. The installer will instruct the homeowner in  
appropriate load management techniques.  
Three methods of determining loads are given here:  
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.

Before removing the load center cover, plan mounting  
location for both Load Manager™ switches. To do so,  
hold a Load Manager™ switch about 18 inches from  
the center of the load center, as shown in Figure 2.  
Figure 2 — Planning Switch Location  
NOTE: The following procedure describes the  
installation of one Load Manager™ switch. Use  
identical instructions to install and test the second  
Load Manager™ switch.  
5. Anchor the Load Manager™ switch to the wall at  
the selected position, as shown in Figure 4.  
1. Ensure there is enough room to mount both Load  
Manager™ switches so their flex conduit attaches  
directly to the load center.

2. Identify appropriate vacant load center 3/4”  
DANGER: Contact with wires and terminals  
inside the load center must be avoided as  
contact may result in dangerous electrical  
shock. Before removing the load center cover,  
switch OFF the main circuit breaker serving the  
load center. Remember that wires on the line  
side of the main circuit breaker are electrically

switch circuit “A”. Turn that load center circuit  
breaker to its “OFF” position. Loosen the screw  
that retains the wire to this breaker, then detach  
the wire. Figure 5 shows the selected load wire  
detached from the circuit breaker.  
Make Sure:  
• The RED wire from the Load Manager™ switch is  
always connected to the circuit breaker.  
Figure 5 — Wire Detached From Breaker  
• The BLACK wire from the Load Manager™ switch is  
always connected to the wire going to the load.  
DANGER! You must connect the Load  
Manager™ switch wires as described or serious  
damage to the equipment or yourself may result.  
9. Select the load center circuit that will become load  
management circuit “B”. Repeat Steps 6 through 8  
for the red and black wires marked “B” coming  
from the Load Manager™ switch.

10. If you wish to connect a 240 Volt AC two-pole  
circuit, such as a well pump, proceed as follows:  
a. Turn off the two-pole circuit breaker used for  
the pump circuit and detach the load wires  
from that breaker.  
7. Find the black and red wires marked “A” that come  
from the Load Manager™ switch. Using good  
workmanship, route both of these wires near the  
selected circuit breaker. Trim and strip the red “A”  
wire and install it properly into the circuit breaker.  
b. Select the four wires marked “C” and “D”  
coming from the Load Manager™ switch  
conduit and route them close to the selected  
circuit breaker(s).  
8. Trim and strip the black “A” wire to mate with the  
wire previously detached from the breaker. Secure  
the wire ends with a wire nut. Neatly dress the  
wires into the load center, as shown in Figure 6.  
c. Repeat Steps 6 through 8 for each pair of red  
and black wires “C” and “D”.
